Emeralds' Geology

Emeralds are gem-quality specimens with a deep, distinctly green colour that came from the beryl mineral family. They are found in igneous, metamorphic and sedimentary rocks at particular geographic regions worldwide.

Scientifically, Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. The degree of green marks the boundary between an emerald and a less expensive green beryl.

Emeralds are composed of a special element of beryllium that is present in very small quantities in the crust of the Earth. The existence of chromium and/or vanadium is what distinguishes emeralds from other gemstones. The trace quantities of these elements cause the green colour of an emerald. In the same place, it is exceedingly unusual for these two elements to ever be found.

Emeralds is one of the most valuable and desired precious gemstones.

In Africa, Asia and South America, ancient cultures independently found emeralds and made them a gemstone of supreme esteem. The emerald serves as the birthstone for people born in the month of May in the United States and several other nations.

Normally, Emeralds are clouded with several inclusions. The existence of the inclusions is generally representats emerald 's source.
