Perché i numeri di registrazione Diamond sono importanti

Jewelry lovers can tell you that, more than any other gemstone, diamonds are often the most sentimental value they own. Especially if the diamond is part of one’s bridal jewelry, there is a lot of emotion wrapped up in a piece. But even so, there may come a day when you may wonder "How to sell a diamond?" There are so many reasons for this question. But there are also many types of outlets, and they can all depend on your reasons and how quickly you need to convert the -piece. Simply put, how to sell your diamond depends on the situation. In this article, we’ll go through several scenarios—all of which will help you create a plan for how to sell your diamonds. Before you ask yourself how to sell a diamond, it’s wise to learn its current value, so you’ll have a starting point. Selling your diamond may take a while, with some work on your end. Most importantly, connect with reliable professionals to buy your diamond for a fair price. Fancy Intense Yellow Cushion Three-stone Diamond Ring Understanding the Value of Your Diamond Understand the current market value for selling diamonds. An appraisal conducted by a certified jewelry appraiser with diamond experience is essential. If you have a grading report from a reputable grading lab, that’s great. If not, and your diamond is on the larger size, consider sending it to one of the well-known gem grading laboratories. An appraisal places a monetary value on your diamond for sale. But a grading report records the quality components of your diamonds like the 4Cs; cut, carat weight, color, and clarity. It does not assign monetary values to your diamond. Consider getting a personal referral from friends who have had a positive experience with an appraiser or a gemological lab. How to Sell a Diamond: Different Approaches You might make appointments with a few types of places before settling on an outlet to sell your diamond. Jewelry Stores You might have done business with a local jewelry store before and have established a good relationship with them. That helps. But the store may take your diamond on consignment. That may take a while to sell. If you don’t mind, this could be a safe trustworthy option. They have to make a profit when they sell it—so your proceeds will reflect that. Pawn Shops Consider a pawn shop for the flexibility it offers. For instance, you can pawn your diamonds and if at some later point (defined in your contract) you can redeem your diamonds back should you want them returned to you. Many pawn shops are experienced in evaluating diamonds. So they could offer you a cash price. But it will be a final sale if that suits you. They have to hang on to jewelry a lot longer than a jewelry store would. So they will offer you less than a jewelry retailer will in most cases. But quick cash may be the way you choose—so that’s good too. LEIBISH 1.21 carat, Fancy Intense Blue Diamond, Oval Shape, VS2 Clarity, GIA Online Marketplace This option is becoming more popular today as online outlets are flourishing. On the plus side, more people will view your diamond for sale, so you might get a better price—or a quicker sale. Platforms like 1stdibs, eBay, Worthy, Facebook Marketplace, craigslist, and the like are all good places to offer your diamonds for sale. They attract more buyers. If many people show interest in your diamonds for sale, you might end up with a bidding war. Still, keep things safe. Ask for cash, or a bank transfer service like Venmo, or Zelle. Show your diamond in a safe place, like your bank for instance—or an office where other people are around. Make the sale on your own terms. You could even do the transaction at the police station if they allow it. Auction Houses When you are trying to sell your high value diamonds or a rare diamond, an auction house may be your best option. You can make an appointment with one of their jewelry specialists who will give you a professional estimate of the value. There’s usually a ‘reserve’—or a rock bottom price to which you won’t go lower. That’s a good safety valve for you. You want it to be win-win for both the seller and buyer. If a good auction house is not in your town, that’s not a deal breaker. Many auction houses have secure methods for shipping (insured of course) items to them. They do this routinely, and you can feel confident in doing this with a reputable auction house. Specialized Diamond Buyers Conduct an online search for specialty diamond buyers, jewelry buyers, diamond bridal jewelry buyers and that sort of thing. You’re going to be surprised at all the resources available only sell other people’s diamond jewelry, especially bridal jewelry. Circa, M S Rau, and I Do, Now I Don’t are places to start although you’ll discover others.  Make a connection with one of the professional associates, and gain confidence in the transaction—before you sell your diamond. Preparing Your Diamond for Sale You only get one chance to make that first impression. So prepare your diamond jewelry for sale BEFORE anyone sees it. Thoroughly inspect your diamond jewelry for loose prongs—or missing stones. Are there any parts that need repair before showing to a potential buyer? Have your item looking as new as possible so someone will want it now. Carefully clean your piece, or you take it to a professional jeweler where they can put your items in an ultrasonic cleaning machine and make it sparkle like new. Fancy Light Brownish Pink Double Halo Ring After you’ve cleaned and repaired it as needed, store it in a box or jewelry bag to keep it free from dust or fingerprints while you get it ready for sale. Now assemble your paperwork—appraisals, purchase receipts, insurance paperwork, and lab reports to accompany your diamonds for sale. These steps are key to a successful transaction. Getting a Fair Price There’s only one way to know if you’re getting a fair price for your diamonds for sale. You have to get an estimate of its current value. What are similar diamond items selling for on the secondary market? Finally, what are you willing to take for this diamond? By answering all these questions ahead of time—you will be more composed during a sales transaction—and you’ll have a more accurate sense of its worth--- and be prepared for an offer for your diamond jewelry. Yes, you can negotiate. Buyers want a ‘good deal,’ so be prepared to accept a bit less than the listed price. Only you know how low to go. It depends on how much cash you need and how quickly you need it. Do your homework so you’ll fix a price reflecting current market trends. By approaching the sale realistically –and adjusting your expectations as necessary, you’ll be satisfied with the outcome. Where to Sell a Diamond for Cash Cash is King, the old adage goes. If you need to convert your diamond jewelry right now—be prepared to accept a steeper discount on the price. Some jewelry stores will pay cash on the spot for your jewelry if they think they can sell it. Of course, many pawn shops will cash you out on the spot, too. There’s no harm in shopping around for the best cash price. Don’t neglect to check with some of the better online sellers who sell just diamonds. They already have a large viewership, and often, they can make you a decent cash offer on the spot, too. LEIBISH Fancy Yellow Radiant Halo Diamond Pendant Tips for Safe Selling More important than getting top-dollar for your diamonds is your need to stay safe. Scams happen and if the deal sounds too good to be true—it probably is. You want cash for your property, and you can meet the customer in your bank—or another public spot where you feel absolutely safe. If the buyer will not meet in person, but wants you to send the item, just don’t. Don’t meet the customer at their place—or a private spot you don’t know. A restaurant where people know you may be a good choice. You can also meet a potential buyer in a jewelry store—that is done frequently. Just chat with the retailer to get their ok first. Don’t meet a buyer at your home. Although it seems like a good idea at first, you can get into an uncomfortable situation.  Your jewelry may be in a safe box at your bank. Meet a buyer there, and if the person doesn’t buy the item---you can place it safely back in the box and eliminate the risk of someone following you to your car. Take a relative or a spouse with you when showing you diamond jewelry. The more back up you have, the safer. Conclusion If you’re thinking about selling your diamond jewelry, you’re in good company. Many people are selling their diamonds today. And there are so many types of outlets to help you. It all boils down to how quickly you want to do the transaction or if you can hold off for more money. Think it through before you start the process. Do you need cash now? Can you wait for the diamond jewelry to sell later but for more money? When considering how to sell a diamond, follow safety guidelines when selling your diamonds by yourself. You can do that successfully. But if you want to remain anonymous, let an auction or a jewelry store sell it for you. This can be a profitable and successful transaction with some preparedness beforehand.

Diamonds Are Good Heat Conductors but Poor Electrical Conductors Diamonds excel at conducting heat, making them invaluable in industrial applications like high-performance heat sinks for electronics. Despite their thermal efficiency, diamonds are poor electrical conductors due to their tightly bonded carbon atoms, which leave no free electrons to carry a charge. 13. The First Engagement Ring With a Diamond Was Given in 1477 In 1477, Archduke Maximilian of Austria presented a diamond engagement ring to Mary of Burgundy, marking the start of a romantic tradition. The ring featured diamonds arranged in the shape of the letter "M," symbolizing their eternal bond. LEIBISH Extraordinary Emerald Diamond Ring  14. Synthetic Diamonds Are Used in Electronics and Cutting Tools Beyond their sparkle, diamonds are vital in modern technology. Synthetic diamonds, created in laboratories, are used in tools for cutting and grinding, as well as in semiconductors and high-performance electronics, thanks to their durability and thermal properties. 15. Only One in a Million Diamonds Is Naturally Colored While most diamonds are colorless or slightly yellow, naturally colored diamonds—such as pink, blue, or green—are exceptionally rare. These unique colors result from impurities or structural anomalies during formation, making them highly prized by collectors. LEIBISH Natural Colored Diamonds  16. Diamonds Can Survive Acid but Will Burn at High Temperatures Diamonds are virtually indestructible when it comes to chemicals and can resist acid corrosion. However, at around 1,292°F (700°C) in the presence of oxygen, diamonds will combust, turning into carbon dioxide. 17. Black Diamonds, or Carbonado: Interesting and Rare Facts About Diamonds Black diamonds, also called carbonado, are typically found in Central Africa and Brazil. Unlike traditional diamonds, black diamonds are polycrystalline, meaning they are made up of many small crystals. They have a unique porous structure and often contain trace elements like hydrogen and nitrogen. Black diamonds are popular in jewelry for their unique color and texture, making them a modern alternative to clear diamonds. LEIBISH Natural Black Diamond 18. Diamonds Can Be Naturally Found in Rivers and Ocean Beds While diamonds are commonly mined from the Earth, they can also be found in riverbeds and even ocean floors. These "alluvial diamonds" are transported by water currents from their primary source and often discovered in gravel and sand deposits. 19. Some Diamonds Fluoresce Under Ultraviolet Light When exposed to ultraviolet (UV) light, certain diamonds emit a soft glow, often blue but occasionally other colors like green, orange, or yellow. This phenomenon, known as fluorescence, can help gemologists identify a diamond’s origin and quality. Diamonds exposed to UV light 20. Natural Diamonds Can Have Unique Inclusions Like Crystals or Feathers Every diamond tells its own story through inclusions—tiny imperfections formed during its growth. These can include crystals of other minerals, feather-like patterns, or even microscopic diamonds. Such features make each diamond truly one of a kind. 21. Diamonds Were First Discovered Over 4,000 Years Ago The first diamonds were found in India around 4,000 years ago. Revered for their mystical and protective qualities, they were initially used as talismans and in religious ceremonies before becoming symbols of wealth and status. 22. How Diamonds Form 90 Miles Below Earth’s Surface: Incredible Facts About Diamonds Diamonds are created deep within the Earth's mantle under extreme heat and pressure. They form at depths around 90-120 miles below the Earth’s surface, in temperatures of over 2,000 degrees Fahrenheit. Volcanic eruptions bring diamonds closer to the Earth’s surface in kimberlite and lamproite pipes. 23. The Argyle Mine in Australia Is Famous for Pink Diamonds Australia’s Argyle mine was renowned for producing over 90% of the world’s pink diamonds. These vibrant gems are extraordinarily rare, with their color attributed to unusual distortions in the diamond’s crystal lattice during formation. LEIBISH 2.19 carat, Fancy Pink Diamond, Radiant Shape, VVS1 Clarity, GIA 24. Diamonds Are Transported to the Earth’s Surface by Volcanic Eruptions Kimberlite and lamproite volcanic eruptions act as natural diamond elevators, carrying diamonds from deep within the mantle to the surface. These eruptions happened millions of years ago, leaving behind diamond-rich pipes for mining. 25. Diamonds Are Used in High-Precision Medical Instruments Beyond jewelry, diamonds have a critical role in medicine. Their hardness and precision make them ideal for surgical blades, particularly in eye surgeries, and their excellent heat conductivity makes them suitable for advanced medical devices.It shouldn’t come as a surprise that there is more than meets the eye when it comes to diamonds. However, some facts about diamonds still manage to boggle the mind and astound us time and time again. That is why, despite all of the imitations out there, there really is no true replacement for a genuine natural diamond. Interested in a closer look?

With so many glittering gemstones on the market today, it can be difficult to sort them all out. Especially if you’re shopping for engagement rings, you’ll want to know your options and how they each compare to one another. That way, you’ll be confident with your purchase. After all, an engagement ring is a big investment—and one that’s meant to last a lifetime. In your search, you may have come across the question of what a simulated diamond is. This is a broad term for several diamond alternatives—they look like a diamond at first glance. But upon deep investigation, you’ll be able to separate them from high-quality diamonds, which offer a lasting investment. LEIBISH Natural Pink Diamond Engagement Ring Introduction to Simulated Diamonds A simulated diamond is a general term covering any number of manufactured stones that are made to mimic a diamond. Of course, they are far less costly than an earth-mined genuine diamond.A simulant diamond can be anything from clear glass to CZ—or cubic zirconia. It can also include Moissanite, which is a colorless created stone and a far less expensive option than a natural diamond. There is some confusion about the term ‘diamond simulant’. It covers many low-cost colorless man-made stones on the market. But lab-grown diamonds, called LGD, are in a separate category because of how they were formed. LGD were made to closely replicate natural diamonds with the same optical, physical, and chemical structure as a genuine diamond. But because they are a manufactured item, they cost very little and have no resale value—unlike authentic natural diamonds. After all the searching, you want to consider what value you are getting for your money with a stone you choose for an engagement ring. What is a Simulated Diamond? A lot of gemstones can be transparent and colorless, so they can be mistaken for natural diamonds. Because they are only concerned with their look and not their actual composition, simulated diamonds can be created from something as simple as glass—and then cut to the shape of natural diamonds. That’s easy enough. A simulated diamond can also be manufactured from any of several chemical components that result in a clear colorless stone suitable for cutting and polishing. CZ, or cubic zirconia, and Moissanite have long been used to simulate an actual diamond. So, for costume jewelry (sometimes called fashion jewelry), they can be a fun, low-cost alternative to real diamonds. They all differ in important areas like hardness, of course. Because of that, they may chip, break in two, or become cloudy –and then they lose all their sparkle. Hardness Comparison between Cubic Zirconia, Moissanite vs Diamonds Simulated Diamonds vs. Lab-Grown Diamonds One well-known alternative to natural diamonds is the LGD, or lab-grown diamond category. These stones are created in laboratories—actually large factories, and are specifically manufactured to replicate the optical, physical, and chemical makeup of natural diamonds. They do a good job of that. But there are huge differences between natural diamonds and the LGD, of course. They are mass manufactured, and so are sold very inexpensively compared to diamonds. While this niche diamond alternative is more durable than the other simulated diamonds we’ve mentioned, it still cannot share the spotlight with an earth-mined diamond, which is a rare stone. Benefits of Choosing Real Diamonds Natural earth-mined diamonds are considered rare objects of great value. Each diamond can be identified by interior and exterior traits that make it one of a kind. It is the hardest known substance on earth, ranking 10 on the Mohs scale of hardness. That means that it is so durable it will last its owner a lifetime—still sparkling brilliantly decade after decade. Diamonds ‘are forever’ the old De Beers saying goes. And they are. They can be passed down to loved ones who will cherish the beauty and sentimental meaning of a real diamond item. Comparison of Simulated vs. Lab-Grown vs. Real Diamonds (Credit Image: Klenota) Buyers often choose diamonds over simulant diamonds of any kind for several reasons. The quality of a real diamond is matchless. The real diamond can be traded up over time if desired. And many diamonds have increased in value over the years, making this choice a wise one. True, a diamond initially costs more than simulants, but it has- and it holds its value for the owner. Now more than ever, buyers shop for all things with their social values in mind. That’s good news for diamond lovers. Today diamonds are ethically sourced and have a paper trail straight back to the mine to prove it. Thanks to many strict policies in place, diamonds are warranted to be conflict-free which sets everyone’s mind at ease. They are a product for our times and for modern shoppers. Conclusion Simulated diamonds offer a very inexpensive way to own sparkly jewelry. While they may look like diamonds at first, they often discolor or chip after much wear and tear. But they can still be a fun purchase for budget-minded buyers. However, there are some very important details to keep in mind if you are thinking about what is a simulated diamond for bridal jewelry. True real diamonds are more costly, but you are investing in something so important for the rest of your life. Over time, you will be glad you have chosen wisely and got real diamonds. They hold their value and can increase in worth over time. They are a valuable symbol of your most precious relationship. And diamonds are the hardest known substance on earth. Diamonds are durable and will keep looking sparkling and new for your entire life. When you have a special jewelry purchase in mind, make sure you opt for real diamonds. You’ll be glad you made the right choice.Explore the History of Diamond Jewelry  

Tra i quattro attributi utilizzati per valutare la qualità di un diamante colorato, il colore è il più importante. I diamanti colorati sono già piuttosto rari; pertanto, quando se ne trova uno di un colore raro, il suo valore di mercato aumenta notevolmente. Alcuni diamanti vengono sottoposti a trattamenti volti a esaltarne il colore, noti come «diamanti trattati», il che influisce sul loro valore e deve essere comunicato ai potenziali acquirenti. Poiché i prezzi di alcune di queste pietre pregiate sono talvolta piuttosto elevati, alcune aziende hanno sperimentato il miglioramento artificiale del colore dei diamanti attraverso diversi metodi. Il miglioramento artificiale del colore è considerato accettabile nel settore, ma deve essere assolutamente comunicato in anticipo a chi acquista le pietre. Infatti, l'origine del colore del diamante, ovvero se il colore di una pietra è "naturale" o "migliorato artificialmente", deve essere indicata nel certificato GIA del diamante. L'origine del colore è indicata nel certificato GIA del diamante Nell'immagine sopra, l'origine è "Naturale" Scopri di più su come leggere un certificato GIA attraverso la guida di LEIBISH "The GIA Colored Diamond Grading Report - a User's Guide" Di seguito sono riportate le tre pratiche più comuni di miglioramento dei diamanti utilizzate nel settore. HPHT Attraverso il trattamento HPHT (alta pressione/alta temperatura) il colore del diamante può essere alterato in modo permanente. Le pietre vengono esposte a temperature estremamente elevate e a pressioni molto elevate. Alcuni sostengono che le condizioni siano simili a quelle in cui le pietre si sono formate milioni di anni fa. Il trattamento è irreversibile poiché essenzialmente migliora artificialmente il colore del diamante. A seconda della pietra, il cambiamento di colore può essere minimo o addirittura piuttosto drastico.  Rivestimento di sovrapposizione Attraverso l'applicazione di un rivestimento di sovrapposizione, il colore del diamante può essere notevolmente migliorato. Il rivestimento contiene spesso fluoruro, ossido di silicio, ossido di alluminio o ossido di titanio. Può essere applicato a parti del diamante, come il padiglione o la cintura, oppure all'intero diamante. Questo metodo di miglioramento dei diamanti è estremamente difficile da rilevare, tuttavia i cambiamenti di colore sono reversibili e possono consumarsi dalla superficie.  Irradiazione La procedura di irradiazione dei diamanti provoca un cambiamento di colore senza causare alcun danno alle pietre. In sostanza, particelle ad alta energia vengono esposte al diamante e provocano un cambiamento fisico del reticolo cristallino del diamante. Questo trattamento crea molti "centri di colore" in tutta la pietra, che quindi emulano un aspetto molto intenso di colori specifici nei diamanti. I trattamenti artificiali sono utilizzati anche per altri miglioramenti dei diamanti, come il miglioramento della purezza. Assicuratevi sempre di esaminare tutta la documentazione necessaria quando valutate l'aggiunta di un diamante alla vostra collezione. I diamanti migliorati sono stati sottoposti a trattamenti per migliorarne il colore o la purezza, il che può influire in modo significativo sul loro valore e sulla loro durata. Questi trattamenti potrebbero non essere permanenti e l'aspetto del diamante può cambiare nel tempo. Inoltre, i diamanti migliorati sono spesso meno preziosi dei diamanti naturali, rendendoli un investimento meno desiderabile. Quando si acquista un diamante, è fondamentale sceglierne uno che sia al 100% naturale e non trattato per assicurarsi di ottenere una pietra di alta qualità con un valore duraturo. I diamanti naturali mantengono la loro bellezza e durata nel tempo, hanno maggiori probabilità di aumentare di valore e sono accompagnati dalla garanzia di autenticità. Per questi motivi, LEIBISH non vende né tratta diamanti migliorati artificialmente di alcun tipo; vendiamo SOLO diamanti naturali al 100% senza alcun miglioramento del colore o della purezza.

It is a given that most people would prefer a large diamond. However, there are a few factors that play into how large it appears against how heavy the stone's carat weight might be. Diamond carat, as one of the basic 4C's of assessing a diamond, is important to understand exactly what carat weight entails in order to select the perfect stone. LEIBISH Two beautiful heart shaped fancy blue diamonds   The heavier the diamond, the more it costs per carat, and even a slight decrease in the diamond carat weight can significantly lower the price. *HINT * When looking to purchase a new diamond, try to find one that is as close to the next carat weight as possible. For example, a stone that weighs in at 1.91ct will cost significantly less than another diamond that weighs in at 2.00 and higher even though it is only a difference of 9 points. The difference in size can be extremely difficult to see and the cost will be quite noticeable. Only, locating diamonds in these sizes are quite difficult since cutters will often do whatever possible not to drop to a lower carat weight.   The Definition of Carat Weight and its History A carat refers to the unit measurement used to describe the weight of the diamond. Many years ago, because of their size, the seeds of the Carob were used on precision scales as units of weight for small quantities of precious stones. This tradition continued through time, hence we refer to the unit measurement as carat.   Carat Measurement Diamonds that come with a grading report will indicate the exact weight to the nearest hundredth of a carat weight. Each carat is divided into 100 points, so if a diamond weighs 3/4 of a carat, meaning 75 points, its weight would be recorded as 0.75 ct. In the industry, the price of a diamond is often referred to by the price per carat (price per unit of 1.00) and is written as P/C (per carat) as opposed to the overall cost of the stone. Additionally, the term "CTW diamond" stands for Carat Total Weight Diamond.   A GIA Diamond Certificate   Read more about how to read and understand the GIA Certification of Colored Diamonds. Fancy color diamonds are already such a rare find. Needless to say, finding a large stone, especially in rarer colors such as Red, Blue, or perhaps even an Argyle Pink diamond is therefore much harder to come by and will be significantly more valuable. Carat Weight vs. the Size of the Stone The carat weight and the size of the stone definitely have a lot to do with one another. However there are a number of factors that are different between the two.Regardless of the diamond weight,, when someone looks at a diamond they often concentrate on the size of the table. Since the table is what everyone other than the jeweler assessing the stone will see, this is the most important aspect of the diamonds appearance. Relative to the diamond boxes shown in the image below, the face value size of each of the stones are quite similar between one another. However, as seen in the image, the carat weight is significantly different between each of the diamonds as a result of the depth of the stones. From left to right: a 0.45ct stone with a 28% depth, a 1.24ct stone with a 46% depth, 0.56ct stone with a 58% depth, and a 1.14ct stone with a 70% depth. The 0.45-carat, pear-shape diamond in the image above has an extremely shallow 28% depth. As a result, it possesses a very large face value size, although it contains a large window in the middle of the stone.The 1.24-carat, pear-shaped diamond has a 46% depth. This is also quite a shallow stone and it includes a small window in the face of the stone.The 0.56-carat, pear-shaped diamond has a 58% depth, which is closest to the most common norm of 60%.The 1.14-carat, pear-shaped diamond has a 70% depth. With such a deep depth, even though it is 1.14-carats it appears somewhat smaller in size although the color of the stone is a little more intensified as a result of the light being trapped within the stone for a longer period of time.   Carat Weight vs. Clarity, Color and Overall Diamond Quality There are times when if a stone includes an external blemish that can likely be removed, or through advanced polishing techniques the color can be maximized, the choice might be made that it is worth taking the risk of putting it back on the polishing wheel. Doing so will most often reduce the size of the diamond, but can result in a higher quality stone. For example, LEIBISH was lucky enough to have won six diamonds in the 2011 Argyle Pink Diamond Tender. One of the stones, a 1.71 Fancy Intense Purplish Pink Diamond, was truly a magnificent piece. However, when Shmulik Polnauer, LEIBISH’s GIA Graduated Gemologist, bid for this stone it was because he saw something no one else could. Shmulik spoke of the time he spent assessing that stone. Even though it already passed the hands of some of the most experienced diamond polishers in the field, he was convinced that if we won that diamond he could maximize its true potential even further. Upon receiving word that the stone was won, LEIBISH took the risk of placing that diamond back on the polishing wheel. The Leibish Prosperity Pink Diamond was repolished into a breathtaking 1.68ct Fancy Vivid Purplish Pink Diamond. LEIBISH's 1.68ct, Fancy Vivid Purplish Pink Prosperity Pink Diamond The example given above is specifically why some experienced diamantaires may take the chance of re-cutting a polished diamond. Only three points were lost on that diamond, but the overall diamond quality was significantly improved.   The Size vs. the Shape The piece of jewelry you choose and the setting in which you place the stone will have a significant effect to the appearance of the size of the diamond. Also, certain shapes always look larger than other shapes even though they might be a lower carat weight. For example, an Oval shape will look longer then a Round shape and will appear to be bigger. A Marquise shape, due to the longish look, also reflects a big appearance in comparison to the other shapes.The two stones below look quite different in size as a result of their shapes, but there really is only 28 points between the two! LEIBISH 3.11-carat, Fancy Deep Grayish Blue, Cushion and a 2.83-carat, Fancy Grayish Blue, Emerald Also, the many variations of the same shape will appear different from one another with regards to the size. For example, the stones below present a different face up value between a Square-cut Radiant, a longer Square-cut Radiant, a Regular style Radiant, and a Rectangular-cut Radiant.     Many characteristics affect the appearance of the stone. For example, a colorless diamond that is cut very well, in a way that light can quickly pass through, will actually appear slightly bigger from the sparkle. Fancy colored diamonds work the same way, only the cut should cause the light to remain within the stone for as long as possible to help accentuate the color. The four attributes (AKA the 4Cs) define the scientific guidelines of assessing the diamond quality, and therefore define the overall value. However, especially with regards to color diamonds, beauty is always in the eye of the beholder. The diamond carat does not always determine the size of the stone. There are a number of diamond dimension characteristics that can significantly change the carat weight while not necessarily changing the size of the table. The 'Table' of the Diamond The table size percentage is the average width of the table divided by the average diameter. Many concentrate on this since it is the section of the diamond we first see. However, the larger the table does not necessary mean the more carat weight the diamond has. Table Size Percentage Diamond shapes will vary and as a result, so will the size of the table. For example, while a 1.00 carat round shape diamond has a 6.5mm table on average, a 1.00 carat princess shape diamond, on average, has a 5.5mm table. 1.02-carat, Chameleon, Round Brilliant Diamond 1.02-carat, Fancy Deep Brownish Yellowish Orange, Princess-cut Diamond   The Depth of the Diamond If the depth of the diamond, measured from the top of the table all the way down to the culet, is deep (otherwise known as a ‘fat’ diamond with an obtuse pavilion angle), the measurement across the top of the diamond is often smaller. If the diamond has a shallower depth (otherwise known as a ‘flat’ diamond with an acute pavilion angle) the table would then be a little larger. The Diamond 'Culet' Some diamond culets are purposely left "open" to cause the effect of an open culet diamond. Below is a 1.31-carat, Fancy Intense Olive Yellow Green, Round Brilliant with an open culet. Have a look at how the minor change affects the appearance of the diamond.     Top View Side View of the Girdle   General Measurements and the Parts of a Diamond  A diamond's density ranges anywhere from 3.15 – 3.53 g/cm3 depending on the compound elements inside. A pure diamond is said to be approximately 3.52 g/cm3. The denser the diamond, the more weight packed within. This means that a diamond with the same as another of equal weight can possibly be slightly smaller in size. Diamond Dimensions The diamond carat is one of the four most important characteristics. However, there are many factors that play into the overall diamond quality.   Naturally Improving the Diamond Quality Inclusions found within the composition of the diamonds are most often there to stay. However, in some cases, if the imperfection is on the external side of the diamond there are those with the ability to remove the imperfection through polishing. Furthermore, in a similar procedure some experienced diamantaires will look at a stone and see the ability to maximize the color through repolishing the stone. Read more about the internal and external imperfections of a diamond. Below are images of a Fancy Yellow, Pear-shaped diamond that LEIBISH modified.  11.24ct, Fancy Yellow, SI2 and 10.79ct, Fancy Yellow, IF   Still, since nine times out of ten it will reduce the diamond weight, and there is always a risk when putting the diamond back on the polishing wheel, there is a lot of consideration that comes into making this type of decision. The diamond can potentially shatter from within which will completely destroy the outside appearance. Meaning, in the blink of an eye, something worth thousands of dollars can easily drop to hundreds or even less. Below are some more amazing examples of some of the modifications LEIBISH has made with our stones. With this Fancy White, Hear-shaped stone, two points were lost through repolishing the stone. However, as can be seen in the images below, the shape was better crafted which increased the value of the diamond. LEIBISH  0.61 carat, Fancy WHITE Diamond, Heart Shape, SI1   The 0.60-carat, Fancy Vivid Blue diamond below is a superb example of why many "gamble" with sending a stone back to the polishing wheel. The shape of the diamond was improved and absolutely no carat weight was lost in the repolishing process. Needless to say, the value of the stone was significantly increased. LEIBISH 0.60-carat, Fancy Vivid Blue   The Potential Risk As mentioned previously, sending a diamond back to the polishing wheel is quite risky. The image below depicts a beautiful Radiant-shaped, Light Pink Diamond that was shattered from within. As a result of the rarity of the color, the stone still has a significant value, only compared to a higher clarity diamond of the same shape, size, and color it could have potentially been worth a lot more.  LEIBISH 1.09-carat, Light Pink, Radiant   Still, like so many other things in life, in order to gain, you sometimes need to gamble. A great example of this was when Lawrence Graff acquired the Wittelsbach Diamond, which later became the Wittelsbach-Graff Diamond at auction in December 2008. The stone that was purchased was a total weight (CTW diamond) of 35.56 carats, Fancy Deep Grayish Blue with a VS2 clarity grade. Besides wear marks, it was chipped and it had an extra large culet.In 2010 Lawrence Graff announced that he had made the very risky decision to polish it down to 31.06 carats and managed to change not only the clarity to  an Internally Flawless but also to improve the color to Pure Fancy Deep Blue with no grayish overtone.

Diamonds are not only some of the most beautiful gemstones on the planet and the most durable substance known to mankind, but they also make worthwhile investments. Therefore, whether you are out there looking for a diamond for an engagement ring or another jewelry piece or are after a potential investment opportunity, you must beware of diamond scams perpetrated by individuals in the diamond industry who want nothing more than to get their hands on your money.Though the large and complex scams are often uncovered by the FBI and the police, diamond scams on a much lower scale that often go unnoticed are lingering right around the corner, just waiting for someone to fall prey to their tricks. Here are several of the most common diamond scams around and the best ways of avoiding them.   Color Treatments Colored diamonds are bought for their sensational colors, durability, and high value. They are also highly sought after because they are very rare. Due to their rarity and high prices, there are those who take advantage of uneducated color diamond customers and lure them with more affordable colored diamonds.The reason these diamonds are more affordable is because they are not what we call Natural Fancy Colored Diamonds, which are diamonds that are found in nature with their beautiful colors, but rather, diamonds that have been treated artificially in order to achieve the unusual coloring. LEIBISH Natural Chameleon Pear Diamond Halo Style Engagement Ring   Though the use of some treatments is acceptable under certain conditions, it is completely unacceptable to sell treated diamonds as natural diamonds, without informing the customer. This type of diamond scam can be found everywhere, and the best way of avoiding them is by requesting the diamond’s certificate stating its color and color of origin.   The Diamond Swap Another common scam that many times goes unnoticed is the diamond swap scam, where the diamond you have chosen is not the diamond you receive. This happens with diamonds of all sorts.After spending much time choosing the right diamond for you and deciding upon a fair price, you pick up your jewel only to discover the diamond inside is not the one you purchased.The best way to prevent this from happening is to view the diamond loosely and to come with someone knowledgeable in the field of diamonds. When possible, look for markers on the diamond that will help you recognize it. Additionally, and likely more important, you should make sure to always get the proper documentation proving the details of your diamond.   Carat Weight Scams The carat weight of a diamond is a very touchy subject, to begin with for many reasons.First of all, most educated and uneducated diamond buyers are usually after the biggest diamond possible, which often includes a heavier carat weight. Prices can change drastically from one carat weight to another (for example a 1.95ct and a 2.03ct), even if it’s only a matter of several points. The FTC actually allows jewelers to round off carat weights; the problem is though, that some do in a rather dishonest way. For instance, a 0.69-carat can be rounded off to 0.75 carats, which is a very popular carat size and much more valuable than 0.69 carats. The buyer will unknowingly pay the higher price and can lose sometimes hundreds of dollars. Therefore, always ask for proof of the diamond’s exact carat weight. Another way in which buyers are scammed in terms of the diamond’s carat weight is when the seller includes the total carat weight, instead of separating it stone by stone. A ring that includes three stones, including one large center stone and two smaller stones can be advertised as having a certain carat weight when in reality that is the total weight of all the diamonds put together, which can be misleading. Once again, by requesting the document verifying each and every diamond’s details, you can avoid such diamond scams. LEIBISH Fancy Yellow Radiant Three-stone Diamond Ring Hiding Diamond Flaws Even the most beautiful diamonds sometimes have flaws, and that’s perfectly okay. What is not all right is when diamond sellers try to mask these flaws or refrain from unveiling them to the potential client. Sometimes a ring setting hides these flaws, which can theoretically be okay as long as it is done with the client's knowledge.Alternatively, diamonds should be viewed loosely so you can get a full view of the whole stone. It is your right to know if the diamond you are interested in contains a flaw, whether visible or not. You can then decide whether or not to buy it, or to use the flaw as a bargaining point. Buying a diamond is not like buying a table. It is not “what you see is what you get” because diamonds are complex, and it sometimes takes an expert eye to see the whole picture. It is also a very pricey and small object with a lot at stake. Much caution needs to be taken when purchasing a diamond, and becoming educated about everything diamond-related, including which scams to avoid, will make your purchase all the more successful and enjoyable.

Spiegazione del certificato GIA: cosa c'è da sapere Il GIA, principale ente di certificazione e autenticazione, ha apportato un cambiamento significativo per quanto riguarda l'autenticazione dei certificati dei diamanti colorati, che possono essere rilasciati per tutti i colori, come i diamanti blu, verdi, rossi o gialli. Tutti i certificati GIA, compresi i rapporti di identificazione e di provenienza (certificati relativi esclusivamente al colore), possono ora essere controllati online per verificarne l'autenticità. Tipi di certificazioni GIA per i diamanti colorati Il GIA (Gemological Institute of America) fornisce due diversi tipi di certificazione per i diamanti colorati naturali fancy. Esiste un certificato completo, noto come Rapporto di classificazione dei diamanti colorati, e un certificato parziale, noto come Rapporto di identificazione e origine dei diamanti colorati. Come verificare il certificato GIA online? Fino a poco tempo fa, era possibile verificare online l'autenticità solo di un rapporto completo di classificazione dei diamanti sul sito web del GIA. Tuttavia, questa modifica consente ora di autenticare qualsiasi rapporto GIA relativo a diamanti colorati naturali, indipendentemente dal tipo di rapporto richiesto. È possibile verificarlo qui. Il Rapporto di classificazione dei diamanti colorati Il rapporto di classificazione dei diamanti colorati, riconosciuto come certificato completo GIA, fornisce tutti i dettagli rilevanti per i diamanti colorati naturali di peso pari o superiore a 0,15 carati, garantendo una valutazione completa della qualità. Il certificato completo GIA include i seguenti dati: Data di emissione del rapporto Numero del rapporto Registro delle incisioni laser (se richiesto) Forma e stile di taglio Misure Origine del colore (naturale o trattato) Grado di colore (tonalità e grado di colore fantasia) Distribuzione del colore (uniformità o disomogeneità del colore) Guida alla purezza (secondo la scala di purezza GIA) Finitura (qualità delle condizioni della superficie e informazioni relative alle sfaccettature) Lucidatura (condizioni generali della superficie) Simmetria (precisione del contorno del diamante e ulteriori informazioni relative alle sfaccettature) Fluorescenza (intensità e colore della fluorescenza del diamante) Diagramma di tracciamento (forma approssimativa e stile di taglio della pietra) Legenda dei simboli, Scala di purezza GIA, Scala dei diamanti colorati GIA, Diagramma delle proporzioni e Caratteristiche di sicurezza (del rapporto per garantire l'autenticità). Come servizio opzionale, può essere inclusa anche un'immagine a colori del diamante.   Rapporto di identificazione e origine dei diamanti colorati Come menzionato sopra, il GIA offre anche un secondo rapporto. Si chiama Rapporto di identificazione e origine dei diamanti colorati (noto anche come certificato "Color Only"). Questo certificato per diamanti è altrettanto valido, ma offre meno informazioni. Si concentra solo sul grado di colore e sull'origine di un diamante colorato ed elenca i seguenti dati. Il rapporto è suddiviso nelle seguenti sezioni: Informazioni generali Risultati della classificazione Informazioni aggiuntive sulla classificazione Diagrammi di riferimento Riferimenti di scala Codice a barre, dichiarazione di non responsabilità e caratteristiche di sicurezza Quando scegliere il Rapporto di identificazione e origine del diamante È sempre preferibile un certificato GIA completo. Tuttavia, se il livello di purezza di un diamante fosse basso, sarebbe saggio richiedere un certificato parziale, poiché è molto meno costoso e manterrà basso il prezzo del diamante.I certificati completi includono i gradi di purezza, le spiegazioni relative al taglio, alla lucidatura, alla simmetria, alla fluorescenza e altre informazioni importanti. Il certificato parziale, invece, non riporta nessuna di queste informazioni e fornisce semplicemente il peso del diamante, l'origine, il grado e la distribuzione del colore, le misure, la forma e lo stile di taglio. Entrambi i tipi di certificato consentono di verificare l'autenticità del diamante tramite la funzione "Report Check" del sito web del GIA. È sufficiente inserire il numero di certificazione GIA per assicurarsi che corrisponda al database dei rapporti GIA. Costo della certificazione GIA Il costo del certificato varia ed esiste un listino prezzi che include tutti i dettagli. Viene calcolato in base al peso, al colore della pietra (bianco) e ad altri parametri. Dipende anche dalla necessità di un'incisione laser e dal tipo di certificato richiesto (parziale o completo).   Il GIA è l'organizzazione più stimata per la certificazione e la classificazione di diamanti e pietre preziose. Fin dalla sua fondazione nel 1931, è stato il punto di riferimento numero uno per qualsiasi questione relativa alla certificazione. Inutile dire che le pietre con l'ambita certificazione GIA sono più preziose, ricercate e preferite. Se vi state chiedendo quale sia il costo della certificazione GIA o quanto costa ottenere una certificazione GIA per i diamanti colorati.   

An absolutely perfect diamond would theoretically be a stone whose crystal structure is perfectly arranged with only carbon atoms. Only, diamonds of this quality are rarely ever found, if they even exist at all. Instead, diamonds are classified into four different types, according to the “impurities” within the structure of the stone. These impurities, which categorize diamonds into Type I Diamonds and Type II Diamonds, should not be looked at as a negative trait, but rather the cause that makes each diamond so incredibly unique.These impurities are nothing like imperfections in the stone and cannot be determined with the human eye, even under a microscopic view. The only way to identify the type a stone might be is through an infrared spectrometer that measures the atomic level in the crystal lattice.According to the chemical build of the stone it will be classified as Type Ia, Type Ib, Type IIa, or Type IIb stone. Interestingly enough, one stone can actually be classified as more than one specific type of diamond, as is the case in most stones in the market today. Tests that are run on the stones in order to determine the type, are administered by organizations such as the GIA when a diamond is sent for certification.   Type I Diamonds Type I is the most common diamond class in nature. These stones contain the addition of Nitrogen atoms within the crystal structure of the stones.   Type Ia The diamond class Type Ia is the compound element structure in most colorless stones. The addition of Nitrogen atoms in Type Ia diamonds is always in clusters that appear throughout the stone. Depending on how the clusters in the stone are broken down, the compounded elements can have an effect on the color of the diamond. Type Ia diamonds are broken down into two sub-divided types: Type IaA and Type IaB. Type IaA diamonds contain pairs of Nitrogen atoms known as A-aggregates. The color of the diamonds is not affected at all due to the fact that Type IaA stones absorb no visible light. Type IaB diamonds contain even clustors of four Nirtogen atoms called B-aggregates. Similar to Type IaA diamonds, the color of the diamonds is not affected due to the fact that Type IaB stones absorb no visible light. Most Type Ia diamonds are actually a combination of Type IaA, Type IaB, and Type N3. Type N3 is groups of three Nitrogen atoms, which actually do absorb visible light. As a result  of the build, the color of these stones can contain a yellowish or even brownish tone. In fact, Cape Diamonds (which are the very beginning of the fancy colored diamond scale) are among the Type Ia diamond class. They often contain a blue toned diamond fluorescence.   Fancy Colored Diamond Fluorescence Under Ultraviolet Lighting Type Ib The Nitrogen elements within the build of Type Ib diamonds are in singular form as opposed to clusters. Type Ib diamonds are far rarer than Type Ia stones, also only about 0.1% of all natural colored diamonds. They absorb both green and blue lights and often show a deeper, more intense tone of the color present in the stone. The bulk of the fancy colored diamonds out in the market, especially those with a higher intensity, are Type Ib.   Type II Diamonds Type II diamonds have no Nitrogen “impurities” within the chemical build of the stone. Diamonds in this class are rarer than Type I diamonds and are often both quite larger and harder. Type IIa Often referred to as “Golconda” diamonds, after one of the first diamond mines discovered in India that supplied the majority of this class, Type IIa stones are the most desirable by collectors. So, what is a Type 2a diamond? Well, they are known for their rarity and exceptional quality.As a result of the compounded elements within, Type IIa stones rarely contain internal imperfections and are famous for their color. White stones of this class with a D color grade are often whiter than other D grade quality stones and sometimes even unofficially referred to as “Super D” or “C” graded diamonds. Fancy colored Type IIa stones have very strong Yellow, Brown, Orange, Pink, Purple, and Red coloring. LEIBISH  4.63 carat, Fancy Intense Pink Diamond, Pear Shape, VVS2 Clarity Needless to say, stones of this type are not common and are a very small percentage of natural diamonds. These stones are cherished by their owners and traded often for investments. The largest compilations of diamonds in this class are from the Argyle mine in Australia and the Golconda mine in India.   Type IIb Similar to Type IIa diamonds, there is no Nitrogen atoms contained in the structure of these stones. However, the addition of Boron is precisely what makes these stones so unique. The Boron element is known to be the greatest cause of a blue tone within the stone. In fact, colorless stones often look better than their actual color grade and fancies of this class are often found with light blue or gray dominant colors.     LEIBISH 0.54 carat, Fancy Intense Blue, Type IIb, Oval An example of a Type IIb Diamond Certificate   Some the most famous diamonds such as the Koh-I-Noor (weighing in at 186 carats) is Type IIa. Below are a few more of the most famous Type II diamonds. Diamond typing (Credit: GIA)   Wrap-up To sum things up about various types of diamonds: Type I diamonds are the most common. They represent 98% of all natural diamonds and have detectable traces of Nitrogen. Type Ia stones contain clusters of Nitrogen atoms throughout the crystal structure of the stone. They tend to emmit a yellowish tone. Type Ib diamonds contain Nitrogen atoms as well. Only, they are all singular as opposed to clustered groups. These stones are 0.1% of all diamonds and emit a strong yellow, orange, brown and even green color tone. Type IIa diamonds are the most valued and collectable items. They contain either very little or no Nitrogen atoms in the crystal structure of the stones. White stones are exceptionally colorless and Fancy Colored diamonds are often found with a brown, purple, or pink tone. They represent only 1% - 2% of all diamonds.  Type IIb diamonds contain elements of Boron within the structure. As a result, they often emit a blue or gray tone. They represent only 0.1% of diamonds. In short, Type IIa and Type IIb stones are the most unique and collectable items. Although, especially in the case of fancy colored diamonds, since no stones are exactly alike it is important to assess each diamond on its own. One should never assume that a diamond will be perfect because it is graded a specific class or that it is worthless because it is of the more common type stones.  

Every diamond fan, whether they are a young consumer shopping for bridal jewelry, or a seasoned gemstone investor has their own reason to love and collect all types of diamonds. There’s more to discover than simply different types of diamonds, although that is helpful in your search. Learning about diamond types including discovering how many types of diamonds exist will help each person develop their own individual preference.   Consumer Classification of Diamonds How many types of diamonds are there in this world? Let’s break it down and dig deeply into this fascinating topic. There’s a misconception between diamond grading (which is condensed into the 4Cs of a diamond ---Clarity, Color, Carat Weight, and Cut) --- and actual diamond types based on their physical properties and chemical properties. To become an expert in diamond knowledge, one must understand both of these concepts. So, first things first. Let’s review all types of diamonds.   Natural diamonds This phrase identifies earth mined natural crystal rough comprised of a single element, and that is carbon. We cannot overstate the importance of this precious gemstone which has been coveted since time immemorial. Diamonds have evolved to mean many things over time. For early collectors, perhaps these shimmering rocks meant power and wealth. We know that because it was early rulers and aristocrats who avidly collected them. In modern times diamonds can still silently convey wealth, but also taste and desirability. Brides love to flaunt their large diamond as a symbol of the couple’s love and the groom’s importance placed on his beloved. LEIBISH 3.01 carat, D Diamond, Radiant Shape, VVS1 Clarity, GIA Lab Grown Diamonds Manufactured diamonds took their cue from the natural diamond world to create a close replica of natural diamonds. Using a miniscule diamond starter seed as they are called, factories have closely replicated the environment of high temperature and high pressure in a closed laboratory situation to develop man-made diamonds. Technological advances made these LGDs possible and at a very attractive price point to consumers. As more factories sprung up the prices kept dropping as the market became flooded with this product.   Compare LGDs and Natural Diamonds It is true that natural diamonds are composed of a single chemical element—carbon. It is the hardest natural substance on earth, ranking 10 on the Mohs scale. But so are lab grown diamonds or LGDs. A natural diamond was uncovered from being some 125 miles below the earth's surface, where it grew over eons of years. That is part of its mystery. Most diamonds display unique characteristics like surface blemished or internal flaws called inclusions. They are not always visible to the naked eye, and many do not detract from their beauty. But what those distinct traits do prove is their authenticity and distinctiveness. Those are some of the ways that experts can recognize a genuine earth mined diamond. Lab grown diamonds on the other hand were developed over just a period of weeks and are crafted to have few if any distinguishing traits. Of course, expert diamond professionals can distinguish between natural diamonds and lab grown diamonds. There’s no romantic story of its discovery when you’re contemplating a lab grown diamond. Each of the countless thousands of stones were made the same way and in short notice. For some shoppers, the relatively low price as contrasted to natural diamonds is the thing that matters. But natural diamond enthusiasts often love the story of their diamond’s origin and relish looking deep into the stone for clues to its origin. Just like the collector, each stone is unique and has its own personal history. Natural diamonds can be very costly depending on their quality and size. The larger the stone and higher the clarity of the diamond means it is exceedingly rare—and in fact, there will never be another such diamond exactly like that. Lab and Natural diamond crystals (Credit Photo: GIA)   Treated Diamonds Natural diamonds can and sometimes do undergo various kinds of industry accepted treatments to enhance their beauty, their clarity and sometimes their color. It is also a complex topic since there are so many treatment types for diamonds. Let’s examine the different types of diamond names and their meaning behind each name. Simply put, diamond treatments are intentional methods applied to diamonds for the end result to be more salable.   Color Treatment for Diamonds Coating - Diamonds can be treated with an ultra-thin coating of different materials including plastics or chemicals. The type of coating is specific to the desired end result. Blue coatings will minimize a yellowish tinge in the diamonds. This treatment is vulnerable to being scratched or completely removed, however. Irradiation - Subjecting diamonds to radiation can change a stone’s color. Taking a cue from nature where natural radiation has turned diamonds green, this process done in a controlled laboratory will result in the stones turning green or blue. The technology is over a century old. Jewelers must be apprised of this treatment in a diamond should it ever have to go to the jeweler’s bench and be exposed to the torch---since these diamonds are sensitive to heat. Annealing – is a process often undertaken after an irradiation procedure of a diamond. By controlled heating then cooling of the stone, the stone may intentionally be changed to brown, pink, orange, yellow, even red, or purple occasionally. This type of treatment is said to be stable for jewelry repairs.   Laser Drilled Diamonds Some natural diamond inclusions are large or dark and noticeable, and that may detract from their beauty. By laser drilling the stone, the inclusions can be drilled out resulting in a clearer more brilliant stone. This process must be disclosed to the consumer of course. In some cases, this drilling may affect the integrity of the stone—making it more fragile.Once the drilling is completed, it can be left as is---there’s a small risk of debris entering the space. Fracture Filling For natural diamonds with natural inclusions called feathers (for flaws resembling a feather with blemishes radiating from a central fracture) a process called fracture filling is employed. Surface reaching feather-like fractures are filled with a glass like substance making these flaws much less visible.  Fracture filling can last for years with proper care but it’s not permanent or stable. It is possible to lose the filling if cleaned via ultrasonic methods or while the item is being repaired. Knowing about these various treatments will help a shopper understand the pros and cons of each one and make an informed decision if it’s right for them. While the impact of diamond treatment to increase the stone’s beauty, you can see that some treatments are permanent, others are not. In many instances, treated diamonds are priced less than their counterpart that has naturally higher clarity or naturally higher color. Fracture Filling close up (Credit Photo: SGL Labs)   Diamond treatments are routinely disclosed by reputable retailers. Because of this transparency, it is not considered unethical to sell or to purchase treated diamonds. Very simply, these stones are processed to become more saleable—and the treatments make this possible.   Natural Fancy Color Diamonds While all natural diamonds are rare and valuable, there is another small sub-set of these precious stones that are called Natural Colored Diamonds, or Fancy Color Diamonds.   Know the Categories of Diamonds Since diamonds are made from just one element, carbon, any other mineral element that intruded into the diamond during its formation phase would alter the appearance of the stone and produce a diamond with color rather than being colorless. For example, if boron is introduced into the diamond while it is forming, a blue tint will appear. Nitrogen lends a yellow hue to diamonds. Some diamond colors are more mysterious though. Natural green diamonds are thought to have been in contact with natural radiation underground. Pink diamonds which hold the world captive are thought to be the result of lattice distortion in the crystal structure. LEIBISH 0.50 carat, Fancy Deep Green Diamond, Cushion Shape, I2 Clarity While all natural color diamonds are rare—some are even rarer within that group. Yellow and brown diamonds are more likely to appear—but red, pink, and blue diamonds are extremely scarce. LEIBISH 0.70 carat, Fancy Purplish Red Diamond, Pear Shape, SI1 Clarity, GIA   Ranking color diamonds as to their rarity must include consideration of the source of their color. Natural color and fancy color diamonds are highly desirable, and much more costly than their colorless counterparts. Treated natural diamonds that take on color are valuable but of course much less than natural color diamonds. Finally, lab grown color diamonds that have been color-enhanced are the least costly of all color diamonds. While the topic of natural color diamonds has only recently been widespread knowledge to the public, in fact, natural color diamonds have existed since diamond mining first occurred centuries ago.The legendary Hope Diamond –that massive blue stone was mined in India centuries ago—in the 17th century. It had changed hands many times, and currently resides in the Smithsonian Museum of Natural History in Washington DC. The Tiffany Diamond is a celebrated cushion shaped yellow diamond discovered in the late 19th century. The gorgeous stone has enjoyed being worn by many celebrities over the years. The Dresden Green diamond was discovered in the early 18th century and escaped being stolen when a bold heist was executed on the Green Vault in Dresden, Germany. Miraculously the famed stone was on loan to the Metropolitan Museum of Art in New York. The Pink Star diamond is not only large but internally flawless—a rare attribute for any diamond, and more so for pink diamonds. It enjoyed travelling to various locations on display until it was sold to Hong Kong jeweler Chow Tai Fook in 2017.

While most consumers are not aware of these classifications, those in the trade are knowledgeable about diamond classifications. When tradespeople classify diamonds, they need to assess their physical and chemical attributes..  The technical classification of diamonds aids the professional in determining a diamond’s formation, any treatment, and importantly its authenticity. Consumers ask, what are the 4 types of diamonds? So, the types of diamonds are technically classified as follows: Type Ia diamonds Indicated nitrogen clusters present in these crystals, producing a yellowish tinge and is the most common type of diamond. Type IIa diamonds These diamonds display no nitrogen impurities. The crystals may have unusual shapes due to the extreme high pressures under which they were formed. These are the rarest and most valuable diamonds because of their outstanding brilliance and colorless qualities. Type Ib diamonds Their dominant features are that individual nitrogen atoms appear scattered throughout the stone (rather than grouped into clusters). This often produces an intense brown, yellow, or orange color diamond which is somewhat rare and very coveted. Type IIb diamonds This is another scarce type of diamond which has no nitrogen atoms. However, these crystals contain boron in addition to carbon. Therefore they have electric conductivity and exhibit a bluish or blue-gray tinge. Read more about Type I and Type II diamonds Conclusion The enormous variety of diamond choices available can overwhelm shoppers at first glance. But becoming familiar with the variables of diamond quality make the differences in pricing much clearer to understand.When considering lab grown diamonds (LGD) enter the process with a clear view that LGDs can be very attractive and easy on the wallet—however there is no resale value with these products. The range of treatment options for diamonds today opens the door to acquiring a larger more beautiful stone and often well within reach. Study the 4Cs so you can understand what drives value. Familiarize yourself with their stable (permanent) treatments and those which are not considered stable. This not only gives the shopper greater understanding as to their value --- but also how to care for these products and extend their life if the stones are deemed un-stable because of the treatment type. When it comes to purchasing diamonds, there is no single ‘right’ choice, it’s simply what’s right for you, your taste, and your budget.

Decoding diamond treatment is a critical topic for today’s shopper—because there are so many treatments out there. We know that not every diamond coming from the earth is gorgeous and free from noticeable flaws. Nature is nature and that’s one of the reasons why flawless (F) diamonds and completely colorless (D) diamonds are almost unheard of. Advancements in technology today offers diamond shoppers treated diamonds that can exceed their expectations. They may cost less than their natural untreated counterpart. These treatments may or may not be permanent (called stable). So one must assess the risks of enhancements and buy with eyes open. Let’s look at all the treatments so you can make an informed decision---and be confident in your purchase.   The phrase diamond treatments covers a broad range of treatment types including, heat treated diamonds, laser drilling, color treated diamonds, diamond filling and coatings. All these treatments are designed to improve the clarity, the beauty and salability of diamonds. But the shopper must dig deeply into this topic to make sure they understand the pros and cons of these treated diamonds. That way, when they purchase, they understand fully if their expectations are met. Many treatments are undetectable to the general public—and a few are even difficult for professionals to detect. So transparency in the buying process is paramount. Reputable diamond vendors and retailers should disclose any and all treatments to the consumer so they will be alert to any special care needed to keep the diamond looking its best.   Understanding Diamond Treatment Methods Coating Diamonds can be treated with an ultra-thin coating of different materials including plastics or chemicals. The type of coating is specific to the desired end result. Blue coatings will minimize a yellowish tinge in the diamonds. It should be noted however, that this treatment is vulnerable to the stone being scratched under normal use,  or having it become completely removed. Color-Coating of diamonds (Credit Photo: Serenity Technologies) Irradiation Subjecting diamonds to radiation can change a stone’s color. Taking a cue from nature where natural radiation turns a diamond green for instance, the radiation process conducted in a controlled laboratory setting will result in the stone turning green or blue. While it sounds rather new, the technology is actually over a century old. High Pressure, High Temperature (HPHT) Treatment This high tech diamond treatment is sometimes referred to as Annealing after Irradiation. It is a specialized process often undertaken after an irradiation procedure of a diamond. By controlled heating and then cooling of the diamond, the stone may intentionally be changed to brown, pink, orange, yellow, even red, or purple occasionally. While extreme care is often warranted with other diamond procedures, this type of treatment is said to be stable, including times when the stone needs to go in for jewelry repairs.   Laser Drilling Some natural diamond inclusions are large or dark and noticeable, and it may detract from their beauty. By laser drilling the stone, (and targeting a specific area) the inclusions can be drilled out resulting in a clearer more brilliant stone. To a trained eye, this process of laser drilling may be detectable. Areas where the lasered diamond was performed will often have a telltale ‘rainbow’ reflecting off the facet when examined under magnification. The stone in a setting will not show this to the naked eye, so the beauty is not impaired. This process must be disclosed to the consumer of course. In some cases, excessive drilling may affect the integrity of the stone—making it more fragile. Once the drilling is completed, it can be left as is without special treatment---but there’s a small risk of debris entering the space. Laser Diamond Drilling (Credit Photo: Diamond Buzz)  Fracture Filling For diamonds with natural inclusions called feathers (flaws resembling a feather) with blemishes radiating from a central fracture, a process called fracture filling is employed. Surface reaching feather-like fractures are filled with a molten glass like substance making these flaws much less visible. Sometimes they are not noticeable at all, and the clarity is improved. Fracture filling can last for years with proper care, but it’s not considered permanent or stable in our industry. It is possible to lose the filling if the stone were to be cleaned via ultrasonic methods or while the item is being repaired. Fracture Filling (Credit Photo: SGL Labs)   Risks Associated with Treated Diamonds We cannot overstate the need for dealing with a reputable retailer if you decide to get a treated diamond of any kind. Reputable retailers should be committed to disclosing all diamond treatments to the consumer—including what to look for and how to best care for the treated diamond.   Detection Challenges Most consumers will not be able to detect treatments in a diamond and must rely on the transparency of their retailer. Most jewelers are committed to providing full disclosure. Reputable grading laboratories should play a prominent role in treatment detection too, so you want to buy a diamond with a laboratory certificate. That being said, there are some retailers who may have treated diamonds in their inventory—without being aware that their goods have undergone treatment, whether permanent or not. That does happens. Those retailers are not trying to deceive consumers—the stones simply slipped by them.   Long Term Stability In review, the irradiation process and the HTHP procedures produce treated diamonds that are considered stable. In other words, the treatment is permanent. But fracture filled, and coated diamonds are not considered to have permanent treatments as there are situations where the treatment can be reversed and needs to be done again. Lasered diamonds are considered to be permanent, however there is a small risk of debris entering the lasered cavity. Additionally, if the diamond had numerous lasered treatment, it could make the stone vulnerable to cracking where multiple lasering occurred.   Importance of Consumer Awareness Transparency in the Industry Both consumers and jewelers must be apprised of treatment in a diamond should it ever have to go to the jeweler’s bench and be exposed to the torch---since some treated diamonds are more sensitive to heat. If an irradiated stone were to undergo work on the jewelers bench without this treatment being disclosed to the jeweler, the consumer may find an altered stone, including an unintended color change.   Educating Buyers You may find the exact diamond you dreamed of from treated diamonds. But it is imperative to know what different treatments are before you go shopping. Here’s a Valuable Tip; Ask questions at the jewelry store where you are shopping. Once you’ve educated yourself on the various types of diamond treatment you can have a more thorough discussion with the retailer—and be assured of getting good value for your money. Another Tip: Request to see a laboratory report for the diamond you’re considering. A reputable diamond certificate will have all the information clearly laid out including an assessment of treatments including specifically which one(s) have been done to the stone. Don’t be afraid to ask for clarification if the report indicates something you’re not sure about. That way you can make an informed choice—and have a frank conversation with the retailer before you buy.   Lab Rough Diamond Flat (Credit Photo: Serenity Technologies)   Natural Diamonds vs Treated Diamonds As you’ve figured out by now, there is a great difference between natural diamonds and treated diamonds. While high quality natural diamonds are more scarce, treated diamonds are abundant and can fill that gap for consumers who want a beautiful stone—yet have a limited budget.   Value Proposition Since high-grade natural diamonds will always be rarer in the market, there is a resale potential for these stones. The lower grade diamonds that have undergone treatment were lesser quality diamonds to begin with. They were purchased at very low prices and then subjected to various treatments to enhance their beauty and salability. Treated diamonds should not be considered in the same category for sustaining value –or increasing it over time. While the more modest budget for treated diamonds makes them attractive to shoppers, the trending patterns today are indicating that shoppers desire natural diamonds over their treated or synthetic counterparts.   Beauty and Authenticity Each consumer has their own reason for choosing natural untreated diamonds. A natural diamond’s unique beauty is magnified by knowing it is an authentic natural stone. But on the whole, the emotional aspect and symbolism of natural diamonds holds a special appeal for shoppers who want their diamonds to reflect the genuine love and commitment for each other. That can only be accomplished they believe, by selecting a natural—completely untreated diamond.   Conclusion Shopping for diamonds is an exciting adventure. The more you know ahead of time, the more informed your decision will be when it’s time to settle on one special diamond. There is nothing wrong with looking at treated diamonds. There are many different processes that diamonds undergo however, so do your homework ahead of time—don’t rely on the jeweler at the store. By understanding the risks of treated diamonds and asking lots of questions, you’ll feel confident in your purchase. You may find a treated diamond that you’re completely happy with---or you may decide that natural untreated diamonds are for you. Authenticity and quality should be at the top of your checklist. This is a purchase to last a lifetime—so choose wisely.    

With so much money at stake today, getting it right the first time when shopping for diamonds is paramount for jewelry consumers. Serious diamond collectors may hear the expression Triple X Diamonds to describe an elite group of expertly polished stones. Triple cut diamond, triple x diamond, triple excellent diamond, triple diamond chart—are you getting confused yet? Even without knowing all the insider’s language, buying a diamond can be intimidating until you learn what the language means. We’re here to sort it out for you and arm you with straight talk to put you in control when diamond shopping. You can’t know all the ins and outs of diamond quality but you can learn the intricacies of shopping for diamonds—then make your own informed decision. Sound good? Let’s go. Did you recently go shopping for a diamond? Did the salesperson bring up terms like triple x, triple ex diamond or even a bit more confusing triple diamond chart? While these inter-exchangeable terms all revert back to the modern concept of triple x diamonds---and there’s so much to learn about it. While it’s a trade term, consumers are beginning to hear it referenced when examining a superb diamond. And as a trade word, you may occasionally hear the phrase triple cut diamonds. It means the same thing. If you hear triple excellent, or even triple ex-diamond, don’t let these throw you off. They are essentially the same expression. Now you know.    Exploring Triple Excellent Diamonds But what does triple X diamonds mean in plain language to the consumer? The expression Triple X Diamond refers to a stone with excellent cut, polish, and symmetry –hence the triple X ranking. These traits will appear on the GIA diamond report—however GIA does not use that exact terminology—they simply state the ranking of those traits.   LEIBISH 5.20 carat, F Diamond, Round Shape, SI2 Clarity, GIA Triple Excellent A Journey into Grading More importantly, does it actually matter that a stone has Triple X rankings? You bet! The more excellent the cut and so on, the better the stone looks. It will have superior brilliance, scintillation, and dispersion. Those aspects of a diamond allow the stone to exhibit a superb light show—and sparkle far across the room as it’s being worn. Significance of Triple X So while you don’t see that terminology on a GIA diamond certificate, if you’re being shown a diamond in a retail setting, you will want to know what this means—since the salesperson will likely mention it when showing you a top-notch diamond. Triple X lays it all out for you, so whether you remember all the subtleties of the Triple X diamond grade or not—you can have assurance of getting a superb stone.   Beyond the Grading—The Nuances of Brilliance Let’s examine things one at a time to better understand this trio of quality factors. After all, you’ll discover so many contributors to brilliance—and each one plays a role. Together, this nuanced array of quality factors adds up to one brilliant diamond.   Impact of Cut on Appearance CUT: This aspect of a diamond is considered to be its most crucial trait, because the cut determines the stone’s proportions —both its depth and each of the angles of its facets. A well proportioned diamond cut will allow the stone to exhibit the greatest amount of sparkle. It’s taken centuries for diamond polishers to understand the effect of cutting on a diamond’s brilliance. So diamond polishing and shaping has evolved continually over time to where it is today. Smooth Surfaces and Crisp Light The Triple Excellent diamond ranking assures the consumer of the most polished smooth surfaces possible on each facet. The result? Crisp light bouncing off every facet back to the eye. This in turn is key to how light bounces around inside a diamond before returning to the eye. Poorly cut diamonds allow much of the light to leak out of the back or sides of the stone causing a dull look to the diamond.   LEIBISH 3 Stone Round White and Fancy Intense Yellow Diamond Halo Ring - Excellent Cut   Misconceptions and Pitfalls There’s myth and then there’s reality when it comes to diamond quality. By learning what the top traits are in diamonds, you can aim for the moon. Myth vs Reality Some diamonds, while not earning a rating of Triple Excellent Diamond, are beautiful stones, because they possess many of the characteristics that fall into the Triple X category. So, don’t disregard a diamond automatically because you don’t see that Triple X ranking. Study it, get familiar with it and let your own judgement direct your decisions.   Pitfalls of solely relying on Triple X But realistically, you may come across a diamond that doesn’t fall exactly in the Triple X diamond niche—but it’s gorgeous. And that’s fine. When you’re happy with your diamond selection, you’re more likely to enjoy its unique traits that make it all yours. But back to our Triple X diamond line-up. We’re talking cut here---take a look. An Excellent cut grade means that a diamond has been cut within certain pre-assigned parameters which in turn allows the diamond to give off its most intense brightness, sparkle, and fire. It also ensures the stone will have an even pattern of light and dark areas that are critical to its dazzle. Poorly cut diamonds, by contrast, may be observed having excessively large light or dark areas that make a stone appear dull or without ‘bounce’ as it is called. What about symmetry, then? Aren’t all diamonds completely symmetrical to their desired shape? Not so much, experts say. Much of the polishing is done by hand, and that’s where human error or negligence can come in.   SYMMETRY: Symmetry is an explanation of the exactness of a diamond’s intended shape. It can be round, called a Round Brilliant, or oval, or any of the other fancy shapes that are popular today. So symmetry refers to several things that ultimately impacts its overall appeal. For example, when gauging symmetry, the expert looks for how well-aligned every one of the facets are and how identical the same types of facets are in shape, angle to each other and so on. This is a big concern as symmetry impacts the shape and proportion In a diamond. With a stone displaying excellent symmetry, all of its facets should meet precisely at the girdle (the widest part of the stone that encircles it in the middle when viewed from the side angle). And looking at the points of the kite-shaped facets appearing on the crown (top of the diamond when viewed in a setting) should align with those points of the wedge-shaped facets on the pavilion side of the stone. This is the bottom portion of the diamond most often hidden by the mounting. Looking at the large table facet appearing in the center of the stone, with excellent symmetry, it should be centered perfectly. Examining the pavilion side of the diamond, one should observe facets on the bottom meeting in a perfectly centered point at the underside tip of the diamond. LEIBISH Extraordinary Fancy Deep Brown Yellow Pear Shape Halo Diamond Earrings - Excellent Symmetry   What effect does all this complex data have on the diamond? A stone graded as having excellent symmetry greatly enhances the diamond’s light return (the light returning to the eye after it has entered the stone). Without understanding why for the novice, excellent symmetry makes a diamond appear more harmonious and perfectly balanced to the eye. Let’s move on to the last of this trio of these Triple X diamond quality factors. POLISH: Focusing on the diamond’s polish grade includes assessing the quality of a diamond’s finish on each of the facets. That means how smoothly (or not) the surface of a diamond has been polished. That’s a difficult task for even the expert polisher to accomplish and some polishers don’t go the extra mile of creating a polish that appears completely smooth under a microscope or jeweler’s loupe. A diamond graded as “excellent polish” exhibits no polish defects visible at 10× magnification which is the jeweler’s loupe. During the polishing process, minute surface defects, including pits and polish lines, are actually often created by the polishing wheel during the polishing process itself. So they need thorough scrutiny before being considered completely done. These tiny imperfections can often be removed through another step of re-polishing. Keep in mind that we’re talking about microscopic imperfections that are usually invisible to the unaided eye.  On the other hand, a conscientious polisher wants to remove these since having these surface defects will dim the brightness and sparkle of the diamond.

The smoother the polished surface, the greater will be the stone’s reflection. A diamond gathers light through its facets which operate like mirrors from all directions by the observer. A diamond having the perfect proportions and exacting symmetry turn that diamond into a dazzling light show. The viewer may not be able to articulate just why the stone looks so brilliant, but he or she can certainly see the results of such expert work. These are stones which display fire and outstanding scintillation. Factors Beyond Grading Fluorescence Considerations The Triple X Diamond ranking is but one of several factors to consider when looking for that all important diamond to cherish. Other elements, like fluorescence for example can impact the appearance of your diamond. When a diamond is subjected to UV lighting can have specific responses. Perhaps some 25-35% of all natural diamonds will show some reaction under this light. But is it bad or good? There are two camps of thinking. Some say it makes the stone look sleepy especially if it has a strong fluorescent reaction. But others remark that it can also help a lower color diamond appear more white! That’s what we want.   Proportions Matter Outside of the Triple X consideration there are other things you may be drawn to or rather not have. Proportions are sometimes a personal thing. With emerald cut diamonds, or pear shaped stones for instance, there is a range of proportions. Some stones are more elongated and certain shoppers love that. Some prefer ratios of length to width that are ‘chubbier’ so to speak. The only way to see what you like is to look at several and then form your own opinion. These qualities may seem complex to understand at first. And you may ask yourself, does it really matter to me? Do I ‘need’ a Triple X Diamond? While the only person who can answer that question is the consumer there are a few things to help make the decision.   Choosing the Right Triple X Diamond A diamond engagement ring is the most cherished piece of jewelry a woman will have for her entire life. There is so much sentiment attached to this diamond---commitment, love and a sense of forever more. When viewed in this context, while a Triple X diamond will cost somewhat more than lesser grade diamonds, the extra cost seems to pale when considering this diamond will be enjoyed daily for the rest of her life. A beautiful diamond tells the story of a couple’s love for one another which is also a thing of beauty to behold. LEIBISH 0.51 carat, Fancy Purplish Pink Diamond, Round Shape, SI1 Clarity, Triple X GIA   Vendor Selection How rare are Triple X diamonds? You might be surprised to learn that in today’s diamond landscape they are not as rare as you would think. We mentioned earlier that diamond cutting evolved over the centuries to become the sparkly jewels we love today.  By going to a reputable vendor you’re free to ask to see several diamonds—in different qualities and shapes. Your opinion is formed after looking at many options—so the more inventory the vendor has, the better it is for your ultimate choice. Knowledge is power we know. So armed with this information, you can embark on a search for the diamond of your dreams, and not be caught off guard by the jargon of the business. You’re in charge here and you should be able to get the best quality diamond within your budget—then you’ll know you have a treasure to be proud of for years.   Consider Additional Performance Reports Did you know some diamonds carry more than one diamond certificate? Or the vendor may not utilize GIA diamond certificates at all. They may utilize the services of other reputable labs to grade their stones. That’s fine. Take a look at the performance report and inspect it for the quality components that you care about most of all.   Conclusion The Triple X diamond cut is the one to go for—being all other factors are equal. This means that you can rely on a superior cut when your diamond has a Triple X ranking. But you need to take a holistic approach. Examining the entire stone for its clarity and color also has great value to you. Do you like the stone you’re considering? Does it stand out for you? These are valid questions only you can answer. So don’t rush to purchase. Now that you’re more aware of what goes on with diamond polishing and the effects each of these factors have on the overall beauty of the stone, your eye is definitely more trained for the subtle aspects of diamond perfection. When you’re at the sales counter looking at diamonds, take your time, and ask yourself, do I love this stone—compared to the others in this tray? Is there a stand-out quality about a diamond that catches your eye? Some experts claim that diamonds ‘speak to the customer’ telling them which one to select. We think that’s probably true. After inspecting a few in your price range, you’ll narrow it down to one or two that really stand out for you. Don’t be afraid to ask questions other than if the stone is a Triple X. Things like fluorescence, clarity and its color grade are all important. While knowledge is power—and there’s no denying that---we also know that your heart will lead you to the perfect diamond for you.  

By now the 4 ‘C’s associated with selecting a diamond – Cut, Color, Clarity, and Carat – should have become entrenched in the minds of consumers as the factors to consider when purchasing a diamond. However, selecting the perfect stone is only three quarters of the pie. In order to complete the circle, you need to know how to care for your purchase, including diamond cleaning.  You have finally taken the plunge and bought that fancy color diamond that had your name written all over it – what now? The color of a fancy color diamond will never fade; however, over time, if you do not care for your diamond in an appropriate manner, it will detract from its luster and shine. After all, the defining characteristic of a fancy color diamond is its color. Should dirt, grit, or grime enter the setting or rest on the stone itself, it can diminish from the stone’s brilliance. Diamond jewelry worn on the body will attract dirt from the environment and from your body. A diamond ring or bracelet has the highest probability of being knocked about and attracting debris as it is worn on the hand. A diamond pendant faces less risk of abuse. Diamonds are made to be worn and there is no need to change your behavior because you are wearing a diamond, as diamonds are one the hardest minerals in the world and are virtually scratchproof. For diamond cleaning, it is recommended to have it professionally cleaned by a jeweler once or twice a year. Jewelers may clean diamond jewelry with steam or ultrasonically. However, it is possible to obtain excellent results at home with the following easy to find accessories – a jewelry cloth, a jewelry brush, and cleaning solution.   The Materials Use a jewelry cloth to wipe the diamond clean before and after cleaning. A flannel cloth or piece of cotton can be substituted for a jewelry cloth. The jewelry brush is used to scrub the diamond and setting of debris. A soft-bristled toothbrush can be substituted for a jewelry brush. Gently cleaning the diamond with a jewelry cloth The diamond cleaning solution helps to loosen the minerals and dirt from the diamond jewelry. Dishwashing liquid, window cleaning solution and ammonia can be used for making your own cleaning solution. The Diamond Cleaning Process Before cleaning, ensure diamond jewelry is secure in its setting. You do not need to be an expert to feel if a stone is loose. If a stone is loose, place the jewelry in its jewelry pouch or box and take it as soon as possible to a jeweler you trust to be repaired. If all diamonds are secure, remove any hair or dust and run the jewelry under a tap for a few seconds. At this stage, diamond jewelry and loose diamonds are cleaned in different solutions. Clean diamond jewelry in hot water with a detergent free soap, such as dishwashing liquid. Loose diamonds should be cleaned in warm water with a solution of 3 parts water to one part ammonia. Window cleaning solution contains a similar formulation and can be used just as effectively. It is best not to let ammonia come in contact with metals as it can damage their color. Let the diamond soak in the cleaning solution for 3-5 minutes to help loosen the dirt Soak jewelry and loose diamonds for 3-5 minutes and then scrub with the brush. Repeat this process 2-3 times. Then dry with the jewelry cloth. Finally, store your diamonds or jewelry properly. It is best to store diamonds in a soft cloth jewelry pouch or its presentation box.   Store the diamond jewelry in its original packing box Caring for your diamonds, and in particular cleaning them, should not be a chore. Use the opportunity as a chance to “bond” with and rediscover your diamonds. And although cleanliness does not affect a diamond’s market value, it usually affects the stone’s value in the eye of the beholder. How to clean diamond jewelry at home? Cleaning diamond jewelry at home requires gentle care to maintain its sparkle and brilliance. Here are some tips for the best way to clean diamonds.  Tips for cleaning diamond necklace at home Fill a bowl with warm water and mild dish soap. Soak the necklace for 20-30 minutes.

Natural fancy color diamonds are not only stunning, but also incredibly rare. In fact, only one of every 10,000 diamond carats that are mined is that of a color diamond. Though they are few in comparison to their colorless counterparts, color diamonds are found in nearly every corner of the globe.Read about the most frequently asked questions about colored diamonds. From Australia to Africa to Siberia and India, color diamonds are mined all around the world. Here is a breakdown of the various countries where different color diamonds are found and a little information regarding the mines responsible for uncovering them.   Yellow Diamonds Let us begin with one of the more commonly found color diamonds: the yellow diamond. The different color intensities of natural yellow diamonds   This joyous colored stone is found primarily in Africa, including Angola, Central Africa, Congo, and Sierra Leone. Additionally, where are yellow diamonds found? They have been discovered in Brazil, Australia, and Borneo. The Ellendale mine in Australia was known to produce about half of yellow stones in the market, but it appears they are no longer operating this year since they suspended operations back in July 2015.   LEIBISH Yellow Diamond Rings   Mostly cape diamonds and low grade colorless stones are found in Angola, but every once in a while the news comes in of a pure yellow diamond discovery of something with a significant size. Central Africa produces very few diamonds, but among those stones are some yellow rough. The Congo is a great example of how more does not necessarily mean better. The country produces a great deal of diamonds, but most of them are low-grade industrial stones.However, every now and then, important finds are made such as yellow diamonds with a strong hue, and even orange and brown diamonds.Lastly, Sierra Leone's diamond production is an essential part of the country's economy. With an annual production average of over 400,000 carats, more than half of that number (over 200,000 carats) was considered gem quality. That is an astronomical percentage. In fact, Sierra Leone is such an important player in the yellow diamond industry that one of its mines, the Zimmi mine, coined the term 'Zimmi Yellow,' after having produced some of the most extraordinary vivid yellow diamonds with the highest levels of saturation on the planet. Borneo mostly has yellow and brown diamonds, and Brazil finds plenty of yellows and browns as well, but has a reputation for producing lower quality stones.   Pink Diamonds Pink diamonds do not need any introduction, as they are extremely popular and loved by all due to their unique soft hue. But where do pink diamonds come from?  The different color intensities of natural pink diamonds   It is believed that roughly 90% of the world's pink diamonds are found in Australia, in the famous Argyle mine. That mine, however, produces other diamonds as well and yet is mainly known for its pink stones.Borneo, Brazil, and sometimes Central Africa are also known to produce the beloved pink gemstone. Borneo mainly produces brown and yellow diamonds but can also occasionally produce green, pink, and blue diamonds. Brazil also mainly produces brown and yellow diamonds, but their stones are known to have a florescence that gives the diamonds a greenish color. In addition to the more commonly found brown and yellow diamonds, Brazil sometimes produces very rare red, green, blue, and intense pink diamonds. The main types of diamonds found in Central Africa are yellow and black diamonds. However, sometimes there are rare pink, blue, and green diamond finds.   Blue Diamonds The Argyle mine in Australia may be famous for its pink diamonds, but the mine also produces a fair number of smaller blue diamonds. The different color intensities of natural blue diamonds   Blue diamonds are not often found in Borneo, but can be some of the rarer Borneo diamond finds. Brazil and Central Africa also don't generally produce blue diamonds, but when they do, are known to produce noteworthy blue diamonds.Now, where does blue diamonds come from? Though India is not well known for its blue diamond findings or its mines, it is the country responsible for two of the most famous diamonds in the world: the Hope Diamond and the Wittelsbach-Graff Diamond.South Africa is home to the Culinan mine (owned by Petra Diamonds), previously the Premier mine, the most important producer of high quality natural blue diamonds in the world. Known for its diamond production in general, South Africa is now almost synonymous with fancy blue diamonds.   Orange Diamonds The uniquely colored diamonds are found in Congo, which is mostly known for producing low-grade diamonds, but can also produce deep yellows, oranges, browns, and combinations of the three colors, here and there. The different color intensities of natural Orange diamonds   Brown Diamonds Another commonly found color diamond; where is diamond brown from ? Brown diamonds are mined in Angola, Borneo, Brazil, Congo, and Australia. The different color intensities of natural brown diamonds In Borneo and Brazil, brown diamonds are some the most commonly mined diamonds whereas in Angola and Congo brown diamonds are considered rare finds. Australia, or the Argyle mine for that matter, is famous for its pink diamonds but actually supplies the world with a great deal of its champagne brown diamonds.   Purple Diamonds Aside from its famed pink diamonds, the Argyle mine in Australia is known to produce a great deal of brown diamonds, as well blue, red, and even purple diamonds. However, the winner of the "main purple diamond producer" title goes to Siberia. The beautiful and rare natural purple diamonds   Green Diamonds Where do green diamonds come from? Green diamonds, renowned for their rare and captivating hue, originate from select regions across the globe.Among the notable sources, the majority of green diamonds are mined in countries such as Brazil, Australia, and South Africa. Brazil, known for its diverse range of colored diamonds, yields some remarkable green specimens. Similarly, Australia, despite its fame for pink and champagne brown diamonds from the Argyle mine, also produces a notable quantity of green diamonds. South Africa, with its rich diamond mining history, contributes significantly to the green diamond market, albeit with fewer occurrences compared to other hues. LEIBISH 0.50 carat, Fancy Deep Green Diamond, Cushion Shape   Red Diamonds  Red diamonds, among the rarest and most coveted of all colored diamonds, are sourced from only a handful of locations globally. The majority of red diamonds are discovered in the Argyle mine in Australia, known for its production of pink diamonds as well. However, red diamonds from the Argyle mine are exceptionally rare, comprising only a minute fraction of its output.Other notable sources include mines in Brazil and South Africa, although occurrences of red diamonds in these regions are sporadic. Due to their extreme rarity, red diamonds command astronomical prices in the market and are highly sought after by collectors and enthusiasts alike. This begs the question: where are red diamonds found? LEIBISH Fancy Red Diamond Black Diamonds If you are wondering where do black diamonds come from, they are mainly found in Central Africa, which doesn't have a big diamond production to begin with. Most of its production is black diamonds and yellow diamonds, but pink, green, and blue diamonds have been found there as well.   Natural black diamonds The origins of the main color diamond colors have accounted for almost every continent, but there are also diamonds found in less common locations such as Canada and the United States. That accounts for six of the seven continents, which says a whole lot.Given the fact that the various diamond colors are caused by a variety of natural elements and factors, it is understandable that each type is typically found in certain regions. Every region has its own type of 'material,' which essentially refers to the compound elements most common in the ground of that area. With the diamond supply at currently operating mines in a state of decline, it is possible that the constant search for additional diamond deposits will result in even more color diamond locations.  

As February comes to an end, why not take a look at this month’s birthstone: the amethyst. Many of us are not familiar with all of the birthstones, aside from the most precious ones such as diamonds, rubies, and emeralds.  However, the remaining birthstones have much beauty to offer, including the amethyst.  The stone’s coloring is purplish, though the shades can vary greatly.  Purples, reds, and violets are warm colors, quite suitable for the winter month. Though an amethyst is no diamond, it is still a beautiful gem and looks great combined with colored or white diamonds. The amethyst is a type of quartz with a violet hue.  There was a Greek myth that amethysts were able to keep drunkenness away and was therefore worn as an amulet around the neck in order to prevent intoxication. For the same reason, amethyst goblets were used for drinking alcoholic beverages. Iron impurities are what cause the purple coloring. Most amethyst stones found today come from Brazil and Uruguay. Before these amethyst locations were discovered, Sri Lanka, India, Germany, and Russia were the primary sources for the amethyst quartz. LEIBISH 33.04 carat, Amethyst, Radiant Shape   Amethyst change color when heated.  An amethyst can take on a bright yellow or brownish-red after being heated to a temperature of only 250 degrees. Since the stone is so sensitive to heat, amethyst jewelry should not be worn in direct sunlight. In contrast to diamonds, amethysts have actually decreased in value. The famous amethyst bracelet belonging to Queen Charlotte of England at the beginning of the 18th century was valued at 2,000 pounds sterling. Two hundred years later, the bracelet was only worth 100 pounds. The decline in price is related to the discovery of amethyst in abundance.  An amethyst can also vary greatly in price based on its quality.  Nevertheless, amethysts are gorgeous stones, especially when set against diamonds.  The result is so spectacular that synthetic imitations are always attempted. Though traditionally diamonds are used for engagement rings, an amethyst can be used as the center stone to reduce the cost, and diamonds used as secondary stones.  Otherwise, an amethyst ring surrounded by diamonds can be a terrific gift. Amethysts look great on bracelets and necklaces as well.  A line of white diamonds around the amethyst can help showcase the stone’s color, or alternatively, a variety of purple diamonds can be used. The combination of the gemstones used is spectacular. LEIBISH Amethyst & Diamond Oval Drop Earrings   Rarity and Value Diamonds are renowned for their rarity and value, often fetching high prices due to their scarcity and popularity in jewelry. On the other hand, Amethyst, while not as rare as diamonds, still holds significant value, especially in its finer qualities.When considering the rarity factor, the comparison between a purple diamond vs amethyst reveals that while purple diamonds are exceptionally rare and consequently command high prices, amethysts, particularly those with deep, vibrant hues, remain relatively more affordable and attainable for many.While amethysts are generally more affordable than diamonds, the worth of an amethyst can vary depending on factors such as size, color intensity, and clarity. So, are amethysts expensive? It depends on various factors, but generally speaking, they are more accessible to a wider range of consumers compared to diamonds. Color and Appearance Diamonds come in a range of colors, but the most sought-after and valuable are typically colorless or near-colorless. However, purple diamonds, while rare, exhibit a captivating hue that rivals that of amethysts.Amethysts, on the other hand, are prized for their distinct purple color, ranging from pale lilac to deep violet. What colors does amethyst come in? The spectrum of colors in which amethysts can appear is fascinating; while the most prized are those with deep purple shades, they can also occur in lighter tones, including pinkish-purple and reddish-purple variations. This diversity in color adds to their allure and versatility in jewelry design. LEIBISH Amethyst briolette, Iolite and Diamond Pendant   Symbolism and Meaning Diamonds are often associated with purity, strength, and eternal love, making them a popular choice for engagement rings and other romantic jewelry. Amethysts, on the other hand, carry a different symbolism. They are often linked to spirituality, wisdom, and clarity of mind. As the birthstone for February, amethysts are believed to promote inner peace and balance, making them a meaningful choice for those seeking spiritual alignment and serenity.  Durability and Maintenance Diamonds are renowned for their exceptional hardness, ranking as the hardest natural material known. Amethysts, while not as hard as diamonds, still boast good durability, suitable for use in jewelry with proper care. However, they may be more prone to scratches and damage compared to diamonds, so regular maintenance and care are important to preserve their beauty over time.While amethysts do not typically change color, exposure to extreme heat or sunlight can sometimes cause fading or alteration in hue.  Whether you or your loved one has a February birthday, or you just like shades of purple and violet, an amethyst can be a fine addition to a piece of jewelry as well as to your jewelry collection.  If you are looking for a stone to combine those colored diamonds with, this may be it.

Achieving a quality photo of a diamond that will show it off in all of its glory takes quite a bit of skill, knowledge, talent – and practice. There is a noticeable difference between a picture taken by a professional and one snapped by an unseasoned amateur. Here are some tips from our diamond photographer for capturing a diamond in the best light, highlighting its undeniable and all-around beauty. The various different color intensities of natural fancy pink diamonds   Sharpness In order to capture the true essence of a diamond (check out the photography in our diamond catalog) or a piece of jewelry (check out the photography in our jewelry catalog) from a technical standpoint, a sharp, crisp focus is needed. The best way to achieve this on a digital camera is by putting the camera on the “spot focus” mode. This way you can control in the most precise way what the camera is aimed at. However, this trick will only get you so far when the subject of the picture is a small stone. For even better results, a camera with a quality manual focus capability is needed. LEIBISH's Diamond Photographer Capturing the Purple Orchid Diamond   Lighting Diamonds photograph best in soft lighting. This means no on-camera flash, which will not only lead to overly lit photos, but it will also cast shadows in the pictures. Continuous diffuse lighting works best for diamond photo sessions.   Stability Getting a great, focused image of a product is critical, so you will want to make sure it won’t move at all while photographing it. In addition, you will often find yourself looking for a shot with the jewelry piece placed in a somewhat awkward position, where there is no way it will stand on its own. Therefore, familiarize yourself with prop wax!   Using wax to connect multiple jewelry pieces  By using this product you can basically position the piece however you see fit and simply edit it out when cleaning the up the final picture.   Bulbs and Tripods As mentioned before, soft, natural lighting works best for photographing diamonds. In terms of bulbs, daylight balanced compact fluorescent bulbs are ideal. These bulbs produce very little heat and can be left on for long periods of time without overheating. Additionally, using a tripod or other camera support is a must. A sturdy tripod is preferred, but anything really is better than no tripod at all.   Positioning Have you ever heard the term ‘a picture is worth a thousand words.’ The angle from where the photograph is taken will show details about the piece that are almost impossible to explain with text. No matter how good the content writer may be, without an image, there are some things that will simply be missed. A good photograph with the right positioning can be the difference between selling an item and having it sit in the safe for a few years. LEIBISH Fancy Intense Yellow Cushion Diamond Drop Pendant (3.99Ct TW)   Props for Contrast Jewelry is special because each piece has a story to tell. When it comes to telling a story, sometimes all you need to do is be creative. As you can see in the images below, the photographer here combined the natural elements of the stone with beautiful plants or flowers of a similar color. LEIBISH pair of Argyle Diamonds from the Tender 2017   Seeing Through the Diamonds LEIBISH Yellow Diamond Ring photographed by Ben  Knowing the technical ropes of photography is key to a successful diamond photo, but it is not the only knowledge required for obtaining an honest diamond image. Understanding what a diamond is and what it does for us as emotional beings is crucial. This means feeling it, seeing it, and digesting what feelings it exudes. Diamonds evoke emotions in human beings. Just like with art, the shapes, forms, and sparkles of diamond arouse sentiment and often stir up memories in anyone beholding their beauty. In a way that differs completely from other objects such as clothing or other fashion accessories, diamonds and jewelry pieces are there to represent one’s personality and heritage. The camera should pick up on this difference that sets every single stone apart from one another, for no two stones are exactly alike. As a result of the cut, the facets may reflect light differently. Therefore, there is a need to adjust the stone accordingly.   Editing How you finish the photograph is sometimes just as important as the photograph itself. Through a good photography software tool, you can learn how to properly manipulate the colors of the image in order to contrast off of the lighting and effects within the image.   An unedited image next to an edited image Another unedited image next to the edited photo Just like anything in life, photographing diamonds takes practice, and lots of it. Even if one is a professional, shooting diamonds can be a challenge if it has never been attempted before. With the help of these tips, the rare and extraordinary stone can be appreciated and represented suitably in a two-dimensional version. Trial and error will eventually end with perfection.

I diamanti naturali Fancy White sono splendidi diamanti di colore bianco opaco. Il termine «diamanti bianchi» viene spesso utilizzato dagli addetti ai lavori e da molti altri per riferirsi ai diamanti standard trasparenti e incolori. Tuttavia, essi non sono trasparenti e incolori come comunemente si crede. I diamanti Fancy White rappresentano un fenomeno naturale tra i diamanti colorati che presentano un intenso colore bianco quando osservati dalla parte superiore. Diamante Fancy White a forma di cuore LEIBISH da 0,62 carati I diamanti colorati sono un'anomalia nel mondo naturale. I diamanti incolori superano i diamanti colorati in un rapporto di circa 10.000 a 1. I diamanti possono presentarsi in molti colori diversi presenti in natura, e i diversi colori si verificano a causa di cause diverse. I diamanti bianchi sono diamanti che presentano una tonalità cromatica percepita simile alla polvere bianca o allo zucchero raffinato e che, in realtà, mostrano un colore bianco neve opaco intrinseco. A differenza della causa caratteristica presente negli altri colori dei diamanti colorati naturali, il colore bianco nei diamanti Fancy White non è il risultato di un elemento composto. Si tratta, infatti, di diamanti incolori che contengono un'alta concentrazione di inclusioni submicroscopiche che diffondono la luce, producendo un caratteristico colore bianco "lattiginoso" e ghiacciato quando osservati dalla parte superiore. La natura di queste inclusioni submicroscopiche è sconosciuta, sebbene si ritenga che siano il risultato della presenza di azoto all'interno della struttura di carbonio puro del diamante. Anello LEIBISH con diamante Fancy White da 4,02 carati e halo di diamanti Fancy Pink Poiché il bianco è un colore neutro, i diamanti Fancy White naturali non vengono classificati in base al loro livello di saturazione, ma vengono semplicemente designati come Fancy White. I diamanti Fancy White sono estremamente opachi e non vengono classificati in base ai gradi di purezza. I diamanti Fancy White sono piuttosto difficili da trovare, anche se LEIBISH ne offre una selezione in varie forme e carature. Diamante Fancy White LEIBISH da 0,64 carati

Everyone who knows of fancy color diamonds will agree that they are absolutely exquisite. When an image of say, a Fancy Vivid Blue is promoted on any of the most prominent social media platforms, the amount of shares and likes are phenomenal, and often more impressive than that of a white stone. Only, there are still many who are not even aware of their existence or fully understand how readily available colored diamonds are. Furthermore, even those that have heard and even seen some of the rarest colored stones assume that they are far too rich for their budget. Well, LEIBISH wants to be of the first to come out and tell them that they are mistaken! Some color diamond are expensive, such as the one mentioned above. However, many others are affordable and some are surprisingly even less expensive than their colorless counterparts! The world of color is vast and the options available are almost endless. Consider the fact that color diamonds can be found in almost any size, they have different clarity grades, different shapes, different cuts, different color combinations, and multiple intensity grades. Each and every diamond characteristic directly affects the overall value of the stone. Hence, there are many strikingly beautiful stones that can be purchased for extremely competitive prices. Fancy Color Diamonds  Depending on certain diamond characteristics, some of these stones come at an extremely high cost and are considered very luxurious pieces. Though, as a result of the many options such as color combinations, overtones, size, and more - the ability to price an affordable stone is there.   Breaking Down the Cost of Color Diamonds As previously mentioned, each diamond characteristic will affect the value of the stone. However, especially with color diamonds, there are certain attributes that weigh in a lot more than the others. The diamond color is by far the most important aspect of these stones. All 100% natural fancy color diamonds are already known as extremely rare natural resources. Therefore the more difficult it is to find the color or color combination, the higher the value of the stone will be. The fact that comparing prices of fancy color diamonds is near-impossible is true. Two color diamonds with identical GIA reports can vary enormously in price, and the reality is that it is all in how good the diamond appears.

Though everything essentially affects the price, following are the most dominant points to consider. Overtone Colors A straight pure color will always hold a higher value than a stone with a secondary hue other than one specific color combination. Specifically with pink diamonds, a Purplish Pink Diamond is valued just as high as a straight Pink. Although, the color diamond family presents so many differences of appearance due to the many characteristics, such as the different color combinations. See for example the image below which contains all the green color diamonds from the World of Color. Color Intensity Fancy color diamonds are found with nine different intensity grades, and the higher the color intensity the more expensive the stone. Not every color possesses each of the 9 intensity grades. For example, a Champagne or Yellow diamond only start from Fancy Light and a Red diamond is only found in one intensity grade, a Fancy Red. Stones with a higher intensity are always priced higher than those with a lower grade.   Diamond Weight Needless to say, the heavier the stone, the more it will go for. Natural color diamonds are not regularly found, and when they are the rough isn’t usually so large. From the rough, the cutter will try to retain as much stone as possible while keeping it a nice shape at a good quality. Diamond Clarity Especially with color diamonds, the clarity is not considered nearly as valuable as the color. None the less, it is one of the 4Cs, the main attributes by which the quality of the stone is defined. So even though the higher the clarity the more expensive the stone, it is quite regular to find a high value color diamond with a lower clarity grade.     Which Color is Better? The beauty of a color diamond is that there is no one color that is better than the others! People are different from one another, and colors talk to people in different ways. Choose the color that fits you best and play around with the wide range of options. It is up to you to adjust the diamond price to your budget.

Tutti i diamanti presentano inclusioni di qualche tipo. Tuttavia, sono il tipo, la posizione e le dimensioni delle inclusioni a determinare il grado di purezza della pietra. Sebbene non sia il più significativo dei quattro attributi in base ai quali viene valutata la qualità di un diamante, il grado di purezza influisce comunque sul valore della pietra. Tutti i diamanti possono contenere imperfezioni, ma solo le inclusioni misurate sulla scala di purezza GIA variano da quelle visibili ad occhio nudo a quelle rilevabili con un ingrandimento di 10X (lente per diamanti) o 30X (microscopio per diamanti). Lente per diamanti LEIBISH con ingrandimento 10X Le inclusioni dei diamanti comprendono imperfezioni interne o esterne alla pietra. Le tabelle sottostanti riportano l'icona, il nome e la descrizione dei vari tipi di inclusioni riscontrabili in un diamante. Ogni inclusione rilevata sarà annotata nel certificato GIA del diamante. Screenshot dal certificato del diamante che evidenzia le inclusioni riscontrate in un diamante a forma di cuore e in uno rotondo Caratteristiche interne Le inclusioni interne possono ridurre il valore delle pietre. Tuttavia, a seconda della posizione in cui si trova l'imperfezione, in particolare la purezza dei diamanti colorati, ciò potrebbe non influire necessariamente sull'aspetto del diamante. A causa dell'aspetto che alcune inclusioni possono assumere, le posizioni nelle pietre in cui si trovano le inclusioni hanno un effetto significativo sul valore complessivo del diamante. A causa della ricchezza di colore in molti diamanti colorati, alcune imperfezioni interne possono effettivamente mimetizzarsi con il colore della pietra.

A seconda del tipo, delle dimensioni e della posizione, a volte vale la pena lucidare leggermente la sezione danneggiata per migliorare la purezza del diamante. Tuttavia, i professionisti a volte preferiscono lasciare l'imperfezione per non perdere il peso aggiuntivo. Di seguito è riportato un elenco delle imperfezioni esterne conosciute insieme all'icona che appare sul certificato GIA.

A diamond can be a girl's best friend, as the famous saying goes, but it can also be her worst enemy. If the stone turns out to be a fake and you don't know how to recognize if a diamond is real, a girl's world can come crashing down around her. The knowledge to detect a fake diamond seems like something only a professional gemologist or jeweler would or should need to know. Believe it or not, there are too many con artists out there trying to sell you a piece of plastic or glass, claiming it is a valuable stone. In fact, not too long ago, a very thoughtful woman gave her daughter-in-law-to-be a beautiful 2-carat diamond engagement ring only to come to the devastating discovery that it was worthless. LEIBISH Extraordinary 2.22Ct TW fancy intense purplish pink and F+ colorless pears, floral designed diamond earrings   Buying diamonds is unlike any other purchase you will ever make. You are buying a rare commodity that is in high demand, which can go for very steep prices. In order to prevent such a horrible scenario, you need to take precautions and become educated in regards to markers pointing at a true diamond. So, we decided to specify a few points that might help.   1. Diamond Certificate of Authenticity First and foremost one should always request the proper certification for any potential diamond purchase. A grading authority such as the GIA, IGI, AGS, as well as an independent appraiser who is affiliated with a professional organization, are the best sources to use as a basis for a diamond's authenticity. A GIA diamond grading report 2. How to Tell if a Mounted Diamond is Real Some of the best diamond imitations have even succeeded in fooling diamond experts, so using your eyes alone to determine whether or not a diamond is real can be tricky, but it can be done. If a diamond is mounted, you should not be able to see through to the bottom of it, if it is in fact a real diamond. The reason is simply because of the way the light passes through the many facets of the stone. If an unmounted diamond is placed face down upon a newspaper, you should not be able to see the writing, and if you can – it's a problem.   3. Can You See Through a Diamond? Only rarely, when the cut is disproportionate, can one see through a real diamond. But, since this is rare, if you can read the text, or see through to the setting, bring it in to have it checked.   4. Diamond Reflection Test A diamond's reflection says a lot. A real diamond will reflect in shades of gray. If you are seeing shining rainbow colors, the diamond is likely a fake. Sometimes one of the only way to identify a genuine natural fancy color diamond is through knowledge and experience   5. Do Diamonds Show Up on X-Ray? While a cubic zirconium can go unnoticed in an X-ray, a real diamond cannot. If you have it X-rayed and the stone does not appear, it is not authentic.   6. Do Real Diamonds Sparkle? Two other quick and simple ways to spot a real diamond is by looking at how it sparkles in light and how much you can see through it. A real diamond appears gray and white inside (brilliance) when held to the light and can reflect rainbow colors (fire) onto other surfaces. A fake diamond will display rainbow colors within the stone when held up to light.  LEIBISH Yellow Stone - Look at how the light sparkles off and through the stone   7. What Does a Real Diamond Look Like? As it can be difficult for the untrained eye to determine what a real diamond looks like, it's always recommended to purchase from a reputable source. LEIBISH Engagement Rings collection   8. How to Tell if a Diamond is Real at Home  Use this simple test to ensure a diamond is real. Find a normal sized drinking glass and fill it ¾ of the way with water. Carefully drop the loose stone into the glass. If the gemstone sinks, it’s a real diamond. If it floats underneath or at the surface of the water, you have a fake on your hands. A real diamond has high density, so the water test shows if your stone matches this level of density.   9. How to Tell if a Diamond is Real using Sunlight The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces.A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.   10. How to Identify a Real Diamond using a Mirror This test, also known as a “scratch test” used to be considered the easiest way to test a diamond. The test is to simply scratch the loose stone against a mirror. The idea is that if the stone is hard enough to scratch the mirror, it’s probably a diamond. However, with today's fakes being made of strong durable materials, this is not a reliable method.    11. Heat Resistance Glass will shatter when brought close to a heat source whereas an original, authentic diamond will be left unharmed. Applying heat to the setting   12. Does it Fog up? Another really quick way to detect a fake is whether it fogs up. (However, I wouldn't recommend you base your decisions purely off of this test.) A synthetic stone will not be able to absorb heat, and so, by simply breathing on a diamond you may be able to get a hint of whether it is real or not. A real diamond will fog (but will immediately clear up) whereas a fake diamond should not be affected at all.   13. Type of Setting While this is not a foolproof method, it applies most of the time. If the diamond is set, check to see if the metal of the ring you are looking at is a poor quality metal such as one with a 'C.Z' stamp, it is most likely that the stone is not real. On the other hand, rings made with 10K, 14K, or 18K gold or that are marked 585, 750, 900, 950, PT, or Plat, are probably holding real diamonds. LEIBISH Fancy Vivid Yellow Cushion Diamond Halo Ring set in a platinum   14. Sand it Down This method might sound somewhat frightening, but keep in mind that diamonds are the hardest natural elements found. You can physically rub a diamond with sand paper and the stone will appear as if it was untouched. If you notice any damage to the stone, it is likely a fake. However, I will be honest. Although I believe this is true, I have never personally tried this method. If you are super brave, let me know what happens, because there is no way I am sanding down my diamond, fake or not!   15. Weigh It Well this one will only work if you have access to a cubic zirconia, a substance often used to replace real diamonds, of a similar size. Interestingly enough, a diamond weighs less than a cubic zirconia. If your stone weighs 55% less then what the cubic zirconia weighs, yours is a real diamond. If it weighs the same, it may very well be a fake. Unfortunately, just like in every other industry, there are scammers who are after easy money. As time goes by there are more and more imitations, but there are also more ways of detecting them before it is too late. Go only to jewelers who you trust, or have qualified reviews proving they are who they claim to be. Aside for the tips mentioned above, it is also possible to purchase a loupe from a jewelry store or to borrow the one on site and to briefly study a diamond through this tool. A real diamond will generally have some imperfections while a fake one will appear completely perfect. Familiarize yourself with what the common imperfections are that appear in diamonds and ask the jeweler any and all questions that you may have. By educating yourself prior to purchasing a diamond you will be protecting yourself from financial loss and emotional strain. In the long run, it is worth the effort.

Se ne è parlato molte volte nelle canzoni. Sono passati quasi 50 anni da quando, in quel giorno, il Sergente Pepper insegnò alla band a suonare e i Beatles cantarono la famosa canzone «Lucy in the Sky with Diamonds». Più di recente, Rihanna canta dei diamanti nel cielo. Ora sembra che i cantanti sappiano qualcosa che la scienza ha scoperto solo di recente. Ci sono alcune cose che sono abbastanza note e documentate quando si parla di diamanti. I diamanti sono solitamente associati al glamour, ai fidanzamenti, ai ricchi e famosi e a tutto ciò che è stravagante. I diamanti provengono da camini di kimberlite o lamproite che sono molto difficili da individuare e da sfruttare. I diamanti si formano quando il carbonio, sottoposto a pressione enorme e a temperature estremamente elevate nelle profondità del mantello terrestre, viene portato vicino alla superficie tramite eruzioni vulcaniche che avvengono sotto la superficie. Tuttavia, trovare diamanti nel cielo, o meglio nello spazio, potrebbe presto diventare una realtà.    Gocce di Giove Una recente scoperta della California Specialty Engineering di Pasadena, in California, a seguito di una ricerca condotta da due scienziati planetari, rivela che i diamanti potrebbero effettivamente fluttuare nell’elio e nell’idrogeno nelle atmosfere più profonde di Giove e Saturno. E non si tratta di diamanti qualsiasi, ma di diamanti così grandi che i ricercatori li hanno definiti “diamondberg”.  E mentre potrebbero fluttuare nell'alta atmosfera, si ritiene che nelle profondità inferiori potrebbe piovere diamanti a causa delle pressioni e delle temperature estreme che effettivamente fondono le gemme. Gli scienziati ritengono che il processo di formazione dei diamanti su Saturno e Giove avvenga quando il carbonio elementare creato da enormi tempeste di fulmini sul pianeta entra nell'atmosfera profonda del pianeta, dove la pressione lo trasforma in un diamante. Man mano che i diamanti si avvicinano al nucleo, si trasformano in liquido. Analogamente a come i diamanti che conosciamo si formano ben oltre le profondità della Terra e possono contenere un elemento combinato, che a sua volta può produrre diamanti naturali dai colori particolari, non è poi così inverosimile immaginare come ciò possa accadere nello spazio.  Si è creduto a lungo che i diamanti potessero esistere su Nettuno e Urano, pianeti relativamente freddi, ma la rivelazione che pianeti molto più caldi come Giove e Saturno possano contenere diamanti è una vera scoperta.   E ora? Potrebbe servire qualcuno come il leggendario imprenditore miliardario e avventuriero Richard Branson, fondatore della Virgin Records e anche della Virgin Galactic, che sta cercando di rendere i viaggi spaziali accessibili al grande pubblico. Il prossimo passo per lui potrebbe essere l’invio di robot per estrarre diamanti nello spazio. I diamanti hanno sempre esercitato un'attrazione galattica sulle persone, attirandole nella loro orbita e tenendole incantate. Una cosa è certa: è solo questione di tempo prima che l'uomo trovi un modo per accedere a questi "diamondberg"; potrebbero volerci decenni, potrebbero esserci battaglie sovrane per i diritti di estrazione, ma non si può mai scommettere contro le persone e il loro insaziabile appetito per i diamanti.

Everyone is fully aware of what a colorless diamond is. In fact, if you don't have one on your finger or if you don't wear one around your neck, there is no doubt that just about everyone else you know does. Naturally, people like to be unique and allow themselves to step outside of the box. Only, when it comes to selecting the perfect gift, a stable investment, or better yet the diamond engagement ring, no one wants to veer too far off track. However, there is one suitable option to use as a replacement that some are not even aware of. This unique and precious stone is known as a natural fancy colored diamond. Fancy Color Diamonds   Over the past ten years colored diamonds have attracted a lot of attention. Only, many still don't know exactly what these fantastic gifts of nature really are. Compared to colorless diamonds are they as authentic, are they real, and most importantly do they really have the ability to retain value as much as some say? A lot of questions have come up whether people want to remain traditional with a colorless stone or add a little color to their life. The latest fashion trends are shouting yellow diamond jewelry and fancy pink diamond engagement rings, but there is still so much to know about these treasures, hence we decided to focus on the most frequently asked questions about fancy colored diamonds.   How are Colored Diamonds Made? The way natural colored diamonds are made is a process that takes place over millions and millions of years. Yeah, that's right, the stone on your finger is really, really, really old! Under conditions of immense pressure and unimaginable heat, Carbon elements form together into rough diamond rocks. The addition of color is simply other elements that compound themselves together with the Carbon. Studies show that high levels of Nitrogen can cause Yellow coloring whereas Boron would cause a bluish tint. Different elements can have different affects to the stones we see. Also, other natural causes, such as radiation which is known to influence a greenish tint, can happen and that will affect the color as well.   Are Colored Diamonds Natural? Natural fancy color diamonds are completely authentic in every way. The colors were developed within the stones through nature and over millions of years formed into the rough stones found in the mines throughout the world. Experienced diamond polishers then work on the rough stones and create the final products we see today. But again, the colors seen are 100% natural unless otherwise stated.   What is the Rarest Diamond Color? Questioning the rarest natural diamond color is actually quite a disputed topic. The majority of people in the trade will adamantly declare that natural red diamonds are in fact the rarest color found. Although it might be true, absolutely pure violet diamonds are seen more infrequently then red diamonds. Therefore, if you were to ask us, we would say Violet, Red, and even Purple are among the rarest colors found.   How do Fancy Colored Diamonds Compare to Colorless Stones? With colorless diamonds the absence of color is what makes them so precious. However, with fancy colored diamonds, it is the presence of color and the intensity of how it shines which makes these pieces so incredible and unique. Colored diamonds are in essence the very same things, only the colors with which they are found make them 10,000 times rarer than the more common colorless stone.   LEIBISH colorless Round diamond next to a Fancy Vivid Pink and a Fancy Vivid Yellow Radiant shape Diamonds   Both colorless stones and natural fancy colored diamonds are assessed by the same four main diamond attributes (color, clarity, cut, and carat). However, unlike colorless stones where they are all considered equal value, the color is significantly more important in fancy colored diamonds. As a result of the rarity of these stones, not only are they used in the most fantastic and articulate pieces of diamond jewelry, but they are collected, traded, and utilized as exceptional sound investments as well.   Are Color Diamonds Real? People often get worried when considering such an important purchase, that they won't get an authentic product. That is actually one of the most common reasons people steer away from natural colored diamonds. However, these people couldn't be any more wrong! The addition of color to the diamond is the minerals that exist in the compound element. It is actually the atomic structure of the stone itself. Having that said, as long as they can assure (with the help of a diamond certificate from GIA, IGI, EGL) that it is a NATURAL fancy colored diamond, there is nothing to worry about. Colored diamonds are just as "real" as any colorless stone out in the market today. Is the Color Authentic? As nice as natural colored diamonds are, some people tend not to approach these stones because they are simply not familiar with the trend. Though these diamonds are beautiful, they are different and unique. However, the colors we see in the diamonds are natural and authentic. Since some natural fancy colored diamonds are so unique, many can often demand a higher cost. As a result, in order to make it more affordable, there are a number of artificial enhancements that some companies make to their stones. First off, there is nothing "wrong" with purchasing an artificially enhanced diamond. However, cubic zirconium for example, which is a great example of a "fake" colorless stone, is not considered by the general public as an authentic stone as it is not a "real" diamond. Artificially enhanced colored diamonds fall in a similar category. When searching for a colored diamond, make sure it is certified NATURAL, and you have nothing to worry about. LEIBISH NATURAL Fancy Deep Blue Oval diamond What colors do diamonds come in? In order to classify the types of diamonds available, the Gemological Institute of America (GIA) developed a uniform list of 12 main colors, 90 secondary hues, 9 different intensity levels, and over 230 color combinations. Diamonds are found with dominant colors of Yellow, Pink, Green, Champagne, Gray, Violet, Blue, Orange, Chameleon, Purple, Fancy White and Fancy Black. The 9 different intensity grades are Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark.   How Rare are Colored Diamonds? The market demand of certain diamond colors over the others has a strong affect on its price. However, the rarity of a natural fancy colored diamond is actually one of the most influential characteristics of its value. Unlike colorless stones, where the "more beautiful" the stone the more expensive it will cost, fancy color diamonds work on an entirely different price scale. Granted, beauty is essential for any product to sell, but "beauty" is the least of any quality diamond's troubles. The rarest diamond colors, such as red, pink, violet, and blue diamonds can be found. However, even the "more common" colored diamonds, such as brown and yellow stones account for less than 0.1% of colorless quality diamond carats. Natural fancy colored diamonds are the rarest gemstones on the planet.   Are Colored Diamonds Natural or Manmade?  We live in amazing times, and given that fact, people today will find a way to do or create almost anything. Science has proved it possible to artificially enhance diamonds and actually influence the colors we see in the stones. However, one they are enhanced, because these stones are not natural, the World Federal Diamond Bureau (WFDB) and the Gemological Institute of America (GIA) said that any stones have been artificially enhanced absolutely must make mention on the certificate as not to fool the consumer.   Are Colored Diamonds Used in Engagement Rings? The first thing any of these lucky ladies will be flaunting after announcing the engagement will be the precious stone on her finger. What better way to prove how unique your love is than to present something that shows her love is like no other. People enjoy standing out from a crowed and there is no better way to do it than a sparkling colored diamond engagement ring. LEIBISH Yellow and red diamonds set as engagement rings   In fact, this fashion trend has attracted so much attention that some of the most famous celebrities have been seen about with their pink or yellow diamond engagement rings.   Which Colored Diamonds are the Most Recommended Investment Pieces? When assessing the price performance of colored diamonds over the past fifteen years, it seems that just about any colored diamond has appreciated in value. However, we recommend that those looking for the right stones to invest in should focus on Argyle Pink Diamonds and high quality Fancy Intense Yellow diamonds above 2.00-carats. LEIBISH Argyle Pink Diamond    As a result of a depleting supply and a very high demand, the realized prices paid at auction for these colors has increased at a phenomenal rate far beyond other investment options one may consider. Are Colored Diamonds Valuable? When it comes to value there are almost no other assets that retain value as well as colored diamonds. Even the strongest alternative investment options in the market, such as Platinum or Gold, have seen a shaky ground through history. However, as a hard asset which people physically claim into their possession, together with the ease of mobility, fancy colored diamonds have recently become sought after by some of the most influential economists as exceptional investment options.   Are Colored Diamonds Worth More?  In general, natural fancy color diamonds are indeed worth more per carat than white diamonds. However, the diamond characteristics will determine the value of the stone. That means that although a natural fancy vivid yellow diamond is worth far more per carat than a white diamond, if it was only 0.50 carats with a low clarity grade and the value was compared with a 50.00 carat flawless white diamonds, logically the white diamond would be worth a lot more. Which are Considered More Beautiful? One of the greatest benefits of a colored stone is that one cannot say that any specific diamond color is more beautiful than another. When looking at a colorless stone one can clearly say that a whiter stone, a D color for example, is indeed more beautiful than a J-H-I colored stone. However, colors speak to people in different ways since people familiarize certain color tones to certain moods or special moments in their life. Regardless of how rare the stone is, some might prefer a blue diamond because they see luxury or prestige while others go for a pink because of the passion and femininity.   Fancy color diamonds are made with 12 main natural diamond colors, 9 intensity grades, and over 230 color combinations. Just have a look at the World of Colors to get a clearer idea of how many variations each stone offers! The image below depicts Pink, Blue, and Green Diamonds with only single colors at different intensity levels. Fancy Color different intensities as shown in Pink, Blue and Green diamonds Can the Everyday Person Afford a Colored Diamond? Some people scare from the words like luxury, thinking this is definitely not for their crowed. Especially after reading such stories of high price tags, or how fancy colored diamonds broke over 13 price records between 2007 and 2012 in the largest auction houses in the world. However, what most people don't realize is that not all colors or intensities are considered "high priced." In fact, a nice Champagne diamond sells for about 30% less than a comparable Yellow diamond and can cost half of what a quality white diamond of the same quality would run them. The prices of colored diamonds vary according to the rarity and market demand. Meaning, that through the wide selection of stones available it isn't all that difficult to find one that fits within your price range. Take all the information you have learned and browse through some of the loveliest precious stones available in the market. You would be surprised at some of the products you can find!

Una leggenda metropolitana è una forma di folklore moderno, costituita da storie che chi le racconta può ritenere vere o meno. E mentre le leggende metropolitane sono spesso una prova di credulità e ruotano attorno a episodi scandalosi, possono anche riguardare qualcosa di più realistico, ma dotato di un certo fascino e di un’aura di mistero. Tuttavia, per quanto riguarda le leggende metropolitane relative ai diamanti colorati di alta gamma, si tratta davvero di leggende metropolitane o forse solo di abili strategie di marketing? Forse il diamante più leggendario al mondo è l'Hope Diamond. Il diamante a forma di pera, con taglio a cuscino, da 45,52 carati, Fancy Deep Grayish-Blue, VS1 (precedentemente "Le bleu de France") è il più grande diamante blu intenso al mondo. La leggenda narra che la forma originale dell'Hope Diamond fosse stata rubata dalla fronte o dall'occhio di una statua scolpita della dea Sita in un tempio indù. I sacerdoti del tempio lanciarono quindi una maledizione su chiunque potesse possedere la pietra scomparsa e nacque così la “maledizione” del Diamante Hope. Il diamante entrò in possesso del re Luigi XIV e passò nelle mani del suo pronipote, il re Luigi XV. Entrambi i re fecero ritagliare la pietra. Il nipote del re Luigi XV e marito di Maria Antonietta, il re Luigi XVI, ereditò poi il diamante. Molti di coloro che entrarono in contatto con la pietra in seguito fecero una fine piuttosto raccapricciante, il che non fece altro che rafforzare la leggenda metropolitana legata alla maledizione originale. Una saga simile era associata al Black Orlov, un diamante da 67,50 carati con taglio a cuscino. La leggenda narra che il Black Orlov, noto anche come "Occhio di Brahma", fosse una pietra nera non tagliata da 195 carati. Si dice che una maledizione fosse stata lanciata su chiunque possedesse la pietra, poiché era stata rubata da un monaco ribelle dall'occhio di una statua del sacro dio indù Brahma, situata in un tempio nell'India meridionale. Questa storia è una coincidenza o un tentativo di sfruttare la popolarità dell'Hope? Il Darya-i-Nur è un diamante rosa pallido da 186 carati con taglio a tavola. È considerato il diamante più celebre dei gioielli della corona iraniana e uno dei più antichi conosciuti dall'uomo. Il diamante Nur-Ul-Ain, di taglio brillante ovale, da 60 carati e di colore rosa pallido, è il fulcro di una tiara disegnata da Harry Winston per il matrimonio dell'imperatrice Farah con l'ultimo scià d'Iran nel 1958. Entrambi sarebbero stati saccheggiati dall'imperatore moghul dell'India dai persiani nel 1739.  Si ritiene che sia il Darya-i-Nur che il Nur-ul-Ain siano stati tagliati dallo stesso raro, enorme diamante rosa pallido da 400 carati, denominato "Diamanta Grande Table" (il Grande Diamante da Tavola), da Jean Baptiste Tavernier, il viaggiatore e gioielliere francese del XVII secolo che vendette l'Hope alla famiglia reale francese. Sottratto a un imperatore? Tavernier? L'India? Sembra delinearsi una tendenza. Se una moltitudine di proprietari contesi è sufficiente per raggiungere lo status di leggenda metropolitana, allora non cercate oltre il Florentine: la leggendaria e irregolare pietra da 137,27 carati, a nove lati e 126 sfaccettature, con doppio taglio a rosa, che un tempo era il grande diamante giallo della famiglia Medici. Si ritiene che il diamante sia stato acquisito dai Medici dopo che il governatore portoghese di Goa, Ludovico Castro, acquistò la pietra grezza dal re di Vijayanagar nell'India meridionale, le cui truppe sconfisse alla fine del XVI secolo. Il diamante giunse poi a Roma, dove fu affidato ai gesuiti. Ferdinando I de' Medici alla fine acquistò il diamante grezzo.  Una versione alternativa sostiene che il diamante sia stato acquistato da Carlo il Temerario, duca di Borgogna (dal 1467 al 1477). Ciò risale a circa 100 anni prima della presunta acquisizione della pietra da parte di Ludovico Castro. Il diamante veniva indossato da Carlo durante le sue campagne militari, che si concludevano invariabilmente con la vittoria del suo esercito. Si parla di un diamante che infonde un potere straordinario.  A rendere ancora più affascinante il diamante fiorentino è il fatto che la sua attuale ubicazione sia sconosciuta. Si ritiene che sia stato ritagliato in un diamante da 80 carati, senza alcuna traccia di cosa ne sia stato del resto. Nel caso dei diamanti sopra menzionati, viene in mente il vecchio adagio: "Non lasciare mai che la verità ostacoli una bella storia". Alcuni pensano che il marketing sia un'invenzione del XX secolo. Tuttavia, l'industria dei diamanti offre una possibilità piuttosto interessante che potrebbero sbagliarsi.

When looking to expand ones diamond collection, people, in general, are looking for the same type of arrangement. The goal is to attain the largest and best quality stone possible for the lowest overall cost. Many characteristics, such as the 4Cs, play extremely important roles in the quality of the precious stones. However, what many don't consider are the features that are relatively blind to the untrained naked eye. Some of these features may slightly reduce the stones overall value, but because they are not easily seen, they won't significantly decrease the quality of the diamonds themselves. Diamond Fluorescence is a perfect example of a one of these features. It can slightly help reduce the cost of the diamond, while not necessarily lowering the overall value of the stone. Those with years of professional experience can often distinguish the slight difference in appearance under regular lighting. However, to the untrained eye, the fluorescence in a diamond is not noticeable unless seen under ultra violet lighting. Fancy Color Diamonds different Fluorescence color What is Diamond Fluorescence  A pure colorless diamond actually has no compound elements of any kind. Only, to find such a prize is absolutely unheard of. The diamonds found are precious stones created with various compound elements absorbed over millions of years in the making. The different elements included in the composition are precisely what define the type of diamond it is. The additional elements that can be absorbed into the diamonds composition and cause fluorescence are nitrogen, boron, and aluminum. Very Strong Green Fluorescence and Strong White Fluorescence The fluorescence is in essence the inclusion of these elements that cause this magnificent glow. Depending on the stones composition, in Fancy Color Diamonds it can appear in a number of different shades or colors such as blue, yellow, white, orange, green, and pink. In colorless diamonds, fluorescence will generally appear only in a yellow or blue tint.Since diamond fluorescence can glow at different levels, the GIA developed a grading scale to measure the strength of the illumination. None Faint Medium Strong Very Strong   If you don’t have access to an ultra violet lamp to view the diamonds, try using a regular black light to cause the affect. Left to Right: Faint, Medium Blue, Strong Blue, Very Strong Blue How it all Began Diamonds were created millions of years ago, deep below the surface of the earth. Over time, while forming, these stones absorbed trace elements of various other minerals. The elements absorbed into the composition of the stones is actually what cause the development of fancy colors as well as the magnificent fluorescent glow. Only about 35% of stones available today actually have fluorescence and only about 10% of those have enough fluorescence to cause a change of appearance under ultraviolet light. The Affects of Diamond Fluorescence Now, more than ever, certain compound elements are admired for the effect caused on the precious stones. Many diamond retailers will tell you that fluorescence is known as a negative trait in the industry. As a result, the price of diamonds that contain this addition are usually slightly lowered due to the 'reduced' quality of the stone. However, there are two points that must be considered about this truly amazing phenomenon: Fluorescence in a diamond can only be distinguished by the untrained eye under ultra violet lighting. Even a very strong fluorescence will appear extremely faint under direct sunlight. Depending on the color of the stone and the color of glow, it can sometimes positively add to the color of the stone. Another point to consider is the fact that because of the slightly negative connotation, it can be an excellent way to get your hands on a beautiful stone that is a little bit above your price range, especially if it is a fancy color diamond where the color is generally rarely affected. As a result of the addition, the cost will most likely be reduced. Depending on the intensity of fluorescence, you might find a little more room to negotiate on the price. Depending on the type of stone you are looking for, the glow can have a different effect on the color. In the following two examples, the fluorescence is specifically what improves the quality of the stone, even though the value will still be slightly lowered. Scenario 1:  A colorless diamond with an 'I-J' color grade and a 'Blue' fluorescence.Under certain lighting, the additional glow can actually help to enhance the color of the stone and make it appear as if it is a higher grade color than the stone actually is. Scenario 2: A fancy colored diamond that is a ' Fancy Intense or Fancy Vivid Green Yellow' stone with 'Very Strong Green'  fluorescence.Under certain lighting, the effect can cause the secondary green to glow, which is a rarer color than the dominant yellow, to shine more intensely and actually improve the color of the stone. Another important point to consider before purchasing a stone is exactly what you plan to do with it. If your plan, for example, is to place more than one diamond on a piece of jewelry, the different fluoresce from each stone might appear as a slight unbalance once put next to one another. However, don't let this stop you from constructing a beautiful piece of jewelry. If it is done right, perhaps with a little professional direction, the outcome can be absolutely magnificent. LEIBISH Fancy Color Diamond Jewelry How Diamond Fluorescence is Viewed in the Industry The question of whether this is a positive or negative trait is actually quite a debated subject. There have been many different opinions on the matter which both argue very true statements. Whether this phenomenon should be considered a positive trait or not, will depend entirely on the color of the diamond and the color of the glow. Not all diamonds fluoresce, and ones that do can be measured. In general, the price will not be affected if it is a 'Faint' fluorescence and might be affected if it's 'Medium' (depends on the characteristics of the stone itself). However, if there is a 'Strong' or 'Very Strong' presence in the stone, the price will likely be reduced.   Colorless Diamonds The resulting effect depends on the color grade of the stone together with the grade and color of the fluorescence. The most common fluorescence in colorless diamonds is blue. In a lower colorless diamond grade, a blue fluorescence may compliment the color of the stone. However, in a higher grade stone, a yellow fluorescence can negatively affect the clarity by withdrawing from the color or causing a milky or cloudy overcast. What can be said with some certainty is that, under the right lighting, it can actually add to lower grade diamonds while taking away from higher grade stones.   Fancy Colored Diamonds In most fancy colored diamonds, the fluorescence might not actually reduce the intensity of the stone. Interestingly enough, the glow together with the combination of the diamond color, can often complement each other. Under the right lighting, this amazing phenomenon can actually help enhance the magic of the color. Finding a yellow diamond with fluorescence is actually quite common. However, the illumination level is usually quite faint. When purchasing a yellow diamond, be sure to speak with the vendor and ask what type of effect the fluorescence has on the stone. In certain cases it might not be noticeable. In others, it can give the stone a slight brownish tint or even a milky appearance. The benefit is that if the fluorescence is not visible, for a significantly reduced cost you can acquire a stone that looks no different from one without any fluorescence at all. Pink colored diamonds, on the other hand, are quite difficult to find without fluorescence. In fact, since the addition is so common, especially in Argyle pink diamonds, even a strong grade will generally not negatively impact the value of the stone. In general, a pure blue diamond will not have any fluorescence at all. In the event that fluorescence is found, which most likely means that the diamond is slightly combined with a greenish overtone, the fluorescence will usually not even be noticeable. Like anything else in life, the rarer things are, the more some want to get their hands on it. Certain shades of fluorescence are even considered by some, collector's items. For example, a red fluorescence is so rarely seen, when it is found it is celebrated. Be sure to ask the jeweler for their recommendations on the stones. Whether positive or negative, to see the affect in reality is breathtaking. Have a look at the image below. Images like this are the reason diamond fluorescence is sometimes referred to as magnificent. Fancy Color Diamond Fluorescence  The colors of the diamonds shown are:From left to right: Fancy Deep Brownish Yellow, Fancy Vivid Yellow Orange, Fancy Vivid Yellow Orange, Fancy Deep Grayish Yellowish Green/Chameleon, Fancy Dark Gray Yellowish Green/Chameleon, Fancy Intense Yellow, Fancy Pink, Fancy Greenish Yellow, Fancy Intense Green Yellow, Fancy Intense Green Yellow. Most importantly, you should be happy with the diamonds you purchase. Make sure to speak to the retailer you are dealing with and find out all the information upfront. Have a look at the stone under different lighting and always look over the certificate.
