1. Are Pink Diamonds Rare?


All natural fancy colored diamonds are considered rare as mined far less frequently then their colorless counterparts. In fact, some studies have shown that only 0.01% of color diamond carats are mined each year in comparison to colorless stones. Pink diamonds are very feminine, extremely beautiful, and among the rarest of the world of colors, just after red, deep violets, and straight purples, and that is why the demand for pink diamond engagement rings has increased so substantially. Because the demand for pink diamonds is so high, while their supply remains so low, the value of some pink diamonds today is tremendous. Hence, the reasons there are many utilizing these stones as investment pieces.

2. How are Pink Diamonds Formed?


The formation of all diamonds is something that happens over millions if not billions of years. Under conditions of immense pressure and heat, Carbon elements form together into rough diamond rocks. Now, it is generally the compound elements that grow within the stones that cause the different colors, but in the case of pink and red diamonds, scientists don't actually know for certain what the cause of the color is. After assessing the stones, the best guess is that it is the immense pressure that causes the pink and red colors. Scientific evidence has shown that Pink Diamonds contain high pressure graining which results in a compressed internal structure and that is thought to be the origin of the color.


3. Are Pink Diamonds Natural?


Pink diamonds are 100% natural, and if that isn't the case, one legally needs to note that the stone is artificially enhanced on the certificate. When the rough stone is found, there is a pinkish tint to the color of the stone. Depending on the intensity of the color and the cut of the stone, the outcome of the natural diamond is sometimes breathtaking. Especially with a pink diamond, because of its value, it is essential to demand a certificate in order to authentic its origin. Although, a lot of progress has been made with artificially enhancing some diamonds, completing the process with a fine pink color is still considered extremely rare, and not many companies possess the skills needed to do this.


4. Where do pink diamonds come from?


Diamonds, in general, are made from the carbon element. They are formed naturally, over 100 miles deep into the earth’s core, where they are heated at approximately 2,200 degrees Fahrenheit and pressurized in unimaginable conditions. They have remained in that environment over millions of years, until cooling to their solid form, which we see today. Pink diamonds specifically are created in the same way, however they are found only in certain parts of the world.


5. What are Pink Diamonds Called?


Color diamonds are named according to an internationally recognized naming pattern, which was developed by the Gemological Institute of America (GIA). First, the carat size is stated, then the intensity of the stone, followed by any secondary hue (also called overtone colors) and finally the dominant color of the stone is mentioned last. For example, a 1.15 carat, Fancy Vivid Purplish Pink Diamond is a Pink diamond (meaning the pink hue is the dominant color present in the stone) with a hint of purple color. The stone weighs 1.15 carats and the intensity grade is called a Fancy Vivid (which is the most valuable intensity grade for a natural fancy color diamond). All color diamonds are considered more valuable when there is only a straight single color and no overtone, other than a purplish pink. This is the only color combination that is valued exactly the same as a straight pink.

6. Why are Pink Diamonds so Expensive?


Less than 0.01% of all diamond carats mined are quality pink stones. The very first question individuals seem to have is regarding the high prices. Indeed, pink diamonds are priced fairly high; significantly higher than, say brown or yellow diamonds. However, the main reason pink diamonds have a name of being pricey is because they are hard to come by and are in high demand. There is more demand than supply and that has a serious effect on the prices. Also, the origin of the stone will also weigh in on the stone. For example, similar to a brand name of any luxury brand, Argyle Pink Diamonds, mined from the Argyle mine in Western Australia are considered some of the best pink diamonds in the market.

Furthermore, some might be looking at Argyle pink diamonds, which are most often priced even higher. These diamonds are found in the Argyle mine in Australia. Due to the color and their successful branding and marketing techniques, Argyle pink diamonds have become like a designer brand that is priced more than others, although they might not necessarily be better in quality.


7. Are pink diamonds cheaper than white?


Diamonds are actually prices per each carat, and the carat price will change depending on the characteristics of the stone. This means that although a pink stone is a rare, if it is low quality and only 0.25 carats, it will likely have a less per carat price than a 100 carat D flawless. However, in general, especially when talking about similar stones, pink diamonds are far more expensive than white stones.


8. Are Pink Diamonds Worth More?


Color diamonds are indeed worth more per carat than colorless diamonds. Only, needless to say, the diamond characteristics will essentially determine the value that these stones may hold. This means that when a 1.50 carat fancy intense pink diamond is compared to a 1.50 carat colorless stone, the pink diamond is worth a lot more than the white diamond. However, if the same 1.50 carat natural fancy intense pink diamond was compared to a similar colorless diamond but of 100.00 carats, obviously, the colorless stone would be worth far more per carat because of its size.

9. Are Pink Diamonds a Good Investments?


One of the basic principles of a good investment is supply and demand. The reasons are because if there is no supply, it will be difficult to source and if there is no demand, what is it good for, other than a nice collection piece. Natural pink diamonds are extremely difficult to source, and the demand increases year after year. Price performance for these stones has proven unbelievable, even when compared to some of the best investment opportunities in the market. The combination of the price performance and some of the greatest advantages these stones hold, pink diamonds boast excellent potential when used as an investment.

10. How much are pink diamonds?


Diamonds are valued according to a wide scale of characteristics. For example, two stones of similar quality can be drastically different from one another, pricewise, if only just the color is a little stronger in one of them. It is therefore rather difficult to list a 'general price.' However, in order to give you a 'ballpark figure,' see the table below for pink diamond prices.


Note: Per carat prices will increase with the size of the stone as it is more difficult to find. Therefore, a 3.5ct stone will have a much higher price per carat than a 0.50ct stone.

11. What Causes the Color?


While most colored diamonds owe their colors to impurities such as nitrogen (yellow) and boron (blue) the cause for pink diamonds is still unclear. Rather than the compound element being responsible for the pink color, it is believed that the unique coloring is a result of the immense pressure the stones endured beneath the Earth’s surface over time. Deformation in the diamond’s crystal lattice is what might be the reason for the pink diamond’s color. Pink diamonds belong to the Type II category of diamonds, which is the rarer and more valuable type. While most diamonds in the world are Type I, only a small percentage are IIa or type IIb, and pink diamonds are included in this rare category.

12. How many pink diamonds are there?


The Argyle mine in Australia, which is recognized as the largest producer of natural pink diamonds, averages an annual production of 8,000,000 carats. Only 1% of that 8 million are graded pink. Many aren’t gem quality and most of those that are gem quality, are very low level quality stones. However, it is important to remember that diamonds never lose their color, or sparkle. The ones mined over 100 years ago are just as good as those found yesterday. They have no shelf life, and there are no second hand stones. Therefore, there are a large number of pinks out in the world, only most aren’t available for purchase.

13. Are Pink Diamonds Real?


Natural pink diamonds are real. “Natural” refers to diamonds that are found in nature with a pink color, and have not been treated in any way order to become pink. This rarity factor is the main reason pink diamonds are so expensive. Because of these factors, certain shades of pink diamonds are incredibly valuable and are considered terrific investments. In order to determine whether a pink diamond is natural or has been artificially enhanced, one needs to look at the GIA certificate where it specifies the origin of the color. It is accepted in the industry to treat a diamond artificially, but it absolutely must be specified that this has been done. There are several methods of artificial color enhancement, some which are reversible and some that are not. Needless to say natural pink diamonds are far more valuable, unique, and special than artificially enhanced pink diamonds.

14. Where Do Pink Diamonds Come From?


Diamonds, in general, are made from the carbon element. They are formed naturally, over 100 miles deep into the earth's core, where they are heated at approximately 2,200 degrees Fahrenheit and pressurized in unimaginable conditions. They have remained in that environment over millions of years, until cooling to their solid form, which we see today. Pink diamonds specifically are created in the same way, however they are found only in certain parts of the world.


15. Where are pink diamonds mined?


The main source for the world’s pink diamonds is the Argyle mine in the Kimberley region of Australia. It is also the most famous mine for pink diamonds, so much so that pink diamonds and the Argyle name seem to go hand in hand. Other sources include the Golconda mine in India, which produces Type I and Type II a/b diamonds, as well as Brazil, South Africa, Russia, and Diavik in Canada. The pink diamonds that are found in Brazil and South Africa often have more of a brownish shade. 


16. Where can I buy pink diamonds?


Most professionals within the trade have never had the opportunity to physically see a pink diamond. Although they are not all that difficult to find, because they are so rare and the price is so much more, most jewelers wouldn't consider such an investment. Therefore, they won't come across those stones unless they attend a large tradeshow.


Having said that, it is far easier than you might think to acquire a natural pink diamond of your own. Especially with online dealers like LEIBISH who offer their stones, together with all the relevant information, images, and third party diamond grading reports, purchasing your own pink diamond is as easy as clicking the mouse and making an online payment.


Pink diamonds are truly unusual gemstones. They are some of nature's most beautiful gifts. Many have recognized the charm and value of these stones, and have already invested in them. Buying a pink diamond is a big decision, and therefore needs to be made very carefully. Hopefully these questions will have been of some help.
