What is an Emerald Gemstone? A Complete Guide
Emerald Gemstone - a Full In-depth Look
What Are Emeralds
A form of the mineral beryl, emeralds rank 7.5 to 8 on the Mohs scale of mineral hardness. Sapphires and rubies rank 9.0 and diamonds are an impressive 10.0. The green color is the result of traces of chromium or sometimes vanadium that is present in the stone. Here is a bit about the fascinating gems.
Emeralds generally contain many inclusions and are therefore considered poor in terms of toughness. A large amount of inclusions also means that emeralds are not graded based on magnification, but rather, on what the eye can see. In fact, as long as there aren’t any visible flaws, the stone is considered flawless.
In addition to the 4 Cs the origin of an emerald can have a huge effect on its price. Approximately 50% to 95% of the world’s emerald production hails from Colombia, though it all depends on the particular year, precise origin, and emerald grade. Colombian emeralds are considered superior to other emeralds thus automatically placing such stones in a more expensive category. Zambia comes in second, with a very high annual production of emeralds as well. It does not end there though. Emeralds are found around the globe, in much smaller numbers of course, in Australia, Egypt, Canada, Norway, China, Switzerland, and even in the United States.
There is no denying the beauty of an emerald, but the attraction does not stop there. Many also see emeralds as a sign of good luck. Due to their rarity, it is difficult to come by a high quality emerald, especially one for an affordable price. That is why there are many imitations out there posing as the real thing. It is important to browse through the stones wisely and become as educated as possible before adding one of these green beauties to your gemstone collection.

The Formation Process of an Emerald
Natural emeralds are the results of geological events that took place in the Earth’s crust hundreds of millions of years ago. Emeralds formed one molecule at a time amid very specific conditions. When hydrothermal fluids escape from magma deep within the Earth’s crust, hydrothermal veins are formed. It is within these veins that emeralds can come to be, assuming that conditions are optimal and elements, such as beryllium, are present. Colombian emeralds, some of the most famous and sought after emeralds on the planet, are formed in this manner. However, not all emeralds are formed in hydrothermal veins. Some are formed in pegmatite deposits. These are similar to hydrothermal veins, except for one main difference. Hot water is the leading element in hydrothermal veins whereas magma or molten rock is the primary agent in pegmatite deposits.
Emerald price and value
Asking about prices for emeralds is pretty much like asking how much a car costs. It really depends on what type of emerald you are looking at. This includes its size, color, color intensity, clarity, and origin. Colombian emeralds for example will demand far higher prices than emeralds from other locations around the globe. Zambian emeralds are a close second. In short, there are a variety of factors that contribute to an emerald stone’s price. Here is a look at some of these factors and which are most important to consider before making an emerald purchase.
What Makes an Emerald Valuable?
Though many gemstones, including diamonds, are assessed in similar ways, each gemstone is evaluated differently. The 4Cs apply here as well, except in this case they stand for color, clarity, cut, and crystal. As with many gemstones including rubies, color is the most important factor. With emeralds, crystal is almost as important. In order for an emerald to be truly valuable it not only must display a pure and intense green color, but it also has to appear transparent for that perfect crystal gemstone look.

Emerald Quality Assessment
The 4 Cs
For those who are unfamiliar with the term ‘the 4 Cs,’ it refers to the four most important aspects of gemstones, including emeralds. While the 4 Cs differ slightly from stone to stone and are mainly known for their association with diamonds, they still play an important role in grading emeralds and determining their worth. Emeralds are graded according to the 4Cs: Color, Clarity, Cut and in the case of emeralds, Crystal. Crystal refers to the transparency of the emerald.
In addition to having a rich green color, an emerald must display great transparency in order to be considered valuable. In terms of color, only emeralds that are medium to dark in tone are considered emeralds. Lighter stones are known as green beryl. The highest quality emeralds, color-wise, are those with a tone of 75%. Just to bring things into perspective, a stone with 0% tone would be colorless and one with 100% would be opaque black. Beryl comes in many other colors, and some are considered gems as well. These include the aquamarine, yellow heliodor, pink morganite, and colorless goshenite. Since an emerald’s glow is more detectable in larger stones, they are generally sold in bigger sizes than some other gemstones.
Though emeralds are classically green, they actually range from yellow-green to blue-green. Emerald color is defined based on three aspects: its hue (color), saturation (intensity), and tone (purity). The more vivid the green, the darker and purer it shows, the more valuable the emerald. Very light emeralds are actually classified as green beryl, whereas medium to dark emeralds receives the prestigious title of emerald. The best emeralds are those that rank 75% in tone, where 0% is a transparent stone and 100% would be opaque black.
Mix of Leibish Emeralds
Every emerald is unique in its own way, but there are some types of emeralds that are special in some way. These include Trapiche emeralds, which display a unique star-like design, and different colored emeralds such as pink or yellow emeralds. All of these varieties are unique and much harder to come by than your typical green stone. There are various price levels among each and every one of these stones, but as a whole, these gems can come with a heftier price tag.
It is normal and natural for emeralds to have inclusions as well as surface breaking fissures. There is a bright side to this, which is the fact that emeralds, unlike diamonds, are graded by the eye and not with the assistance of a magnifying device. All it takes for an emerald to be considered flawless is for it to appear clean, without any visible inclusions, to the eye. High quality emeralds, which are stones that are eye-clean, display a vivid primary green color, do not contain anymore than 15% of a secondary color, and showcase a medium dark tone, demand exorbitant prices.

How To Detect A Genuine Emerald

However, when it comes to colored gemstones, particularly emeralds, how is one to know whether or not he or she is looking at the real deal?

Gemstone Vs. Glass
In addition to the many different types of natural and synthetic gemstones that may be posing as authentic emeralds, there are simple glass stones hoping to be mistaken for natural emeralds. Similar to other impostors, glass will likely have bubbles and may also display scratches. If the facet cuts are rounded, you are probably looking at glass. While emeralds don’t rank the highest on the Mohs scale of hardness, they are certainly sturdier than glass. Purchase a Mohs kit in order to test the stone’s hardness. If it is real it should rank 7.

Emerald Stone Benefits
Most people do not select emeralds as their first gemstone due to several reasons including the popularity of other stones such as diamonds, the prices, and the unique yet very specific color. Unless the emerald happens to be your birthstone or you have a thing for green stones, chances are emeralds won’t make it into your jewelry collection so quickly.
One does not have to be born in May in order to be able to buy or wear an emerald. The green stone offers so much in terms of appearance. Green emeralds can range in terms of color and intensity so that those in search of a softer hue can be satisfied as well as those looking for a dark and deep shade. The range of colors makes this stone suitable for various skin tones as well as body types. A bright green stone is a terrific way to express one’s bubbly personality and can instantly spice up an ensemble. Colorless diamonds, pearls, and the different types of precious metals may go with practically everything, but emeralds have the rare ability to provide a great deal of color and personality to the table without involving any synthetic materials.
We obviously cannot promise any of these beliefs, but similar to the energetic powers of other stones, it is said that the emerald is full of meaning.
