They are so common that it’s almost impossible to find a stone without any flaws. Unlike beryls, which are mined from pegmatites, most emeralds are mined in regions with metamorphic-rock environments, where pegmatites intersect with ultrabasic rocks or schists (source of chromium).Īn active metamorphic environment where emeralds are formed results in numerous inclusions or fractions in emeralds. Natural emeralds form when beryllium, aluminum, silicon, oxygen, and one or more of the trace elements that cause its characteristic green color (chromium, vanadium) come together in the correct geological environment. This year the GIA Laboratory confirmed that Brazilian green beryl was indeed emerald. This beryl was not colored by chromium, as it was accepted previously, but by vanadium. However, the situation changed when a perfect emerald-colored green beryl from Brazil was discovered. Until 1963 chromium was considered to be the only valid cause of emerald’s green color. Emerald will show red colors under the Chelsea filter because of Cr. Emerald is usually highly included and fractured. The color is explained by chromium and vanadium trace elements’ presence. Now gemology knows the beryl mineral group and can differentiate two closest brothers, by less than 1% amount of trace elements.Įmerald can be identified by bluish-green to green, with strong to vivid saturation and medium to medium-dark tone. It is believed to be Cleopatra’s most favorite gemstone in times when there were no mineral formulas and trace elements. ![]() It was known to humans from Ancient Egyptian times. How to Identify BerylĮmerald is truly a legendary stone. To sum up, the green color is purer when the iron content is relatively low. When iron content is relatively high, the emerald has a bluish hue in its main green color. Generally, the higher the chromium or vanadium content, the more intense the green color.Īt the same time, iron affects the amount of blue. To find some more precise evaluation factor than just individual perception of color, the next characteristic exists. Even among that group, however, there’s a difference of opinion about what’s considered “too light.” “To most gemologists, gemological laboratories, and colored stone dealers, it is more correct to call a stone green beryl when its color is too light for the stone to be classified as emerald. The most trustworthy gemological laboratory in the world make the next statement regarding emerald and green beryl boundary: The difference between green beryl and emerald is their color, tone, and saturation due to the presence of chromium and/or vanadium in emerald. Every emerald is technically beryl, however not every beryl is emerald. ![]() However, minor contents of iron, chromium, vanadium, or manganese change the color of the mineral without changing the structure and chemical formula of the beryl mineral.īeryl is a group of minerals, which include emerald, aquamarine, red beryl, and others. Beryl is a mineral with the defined chemical formula Be 3Al 2Si 6O 1 8. ![]() Their similarities and differences are not always highlighted, so there are some misunderstandings. Emerald Is Beryl the Same As Emerald?īeryls and emeralds are closely related. Is Beryl the Same As Emerald? The Main Differences Beryl vs. If you are interested in checking out the best books about rocks and minerals identification you can find them by clicking here (Amazon link). After reading the article, you will never mix these two mineral species, for sure. What makes beryl a precious emerald variety and how to draw a distinct border between brothers is going to be thoroughly discussed further. Both chemically and structurally, they are the same material however, the price for emerald and green beryl is dramatically different. ![]() The strong to vivid saturation and medium to the medium-dark tone of emerald distinguish it from light-green colored green beryl.īeryl and emerald have the same chemical formula. The main difference between emerald and green beryl is that emerald color is influenced by chromium and/or vanadium trace elements. Fewer people know that mineralogically emerald is a variety of beryl group minerals.Įmerald is a vivid green variety of beryl. Persons who are not even interested in gemstones and minerals are familiar with the name emerald and know that it usually stands for lush green color.
