It has a specific Gravity of 2.71, mean refractive index is 1.58 and hardness is 7.5 on the moh's scale.

OCCURRENCE

Emerald is found in Colombia, Brazil, Russia, Tanzania, South Africa, India, Australia, Austria, Pakistan, Kenya and Zambia. In India, Emeralds are found in Rajasthan, Orissa and Madhya Pradesh.

IDENTIFICATION

Emeralds from various mines have different kinds of inclusions. These inclusions can be seen with the naked eye, or else under magnification. If no inclusions are seen even under magnification, the chances are that the Gem under examination is either a piece of glass or a fake. The inclusions in Emeralds include flakes of mica, inclusions like fibre, milky white spots, straw and bamboos and small cubes of rock salt are also seen sometimes. Black spots are also seen in Emeralds.
Emeralds were formed when lava coming out from the volcanoes solidified on the surface of the earth. At this stage its fast solidification led to certain flaws in its crystal formation and certain foreign elements also got into it. The synthetic Emeralds contain nail-like inclusions, brush-marks or chains of bubbles.
