About Emerald Gemstone
The name emerald derives from greek smaragdos. It means €œgreen stone and, in ancient times, referred not only to Emerald but also probably to most stones. Emerald is the most precious stone in the beryl group. Its green is incomparable, and is therefore called Emerald green. The colouring agent for the real Emerald is chrome. Only the finest specimens are transparent. Often the Emerald is clouded by inclusions. These are not necessarily classified as faults but are evidence as to the genuineness of the stone as compared with synthetic and other imitations.
Emerald is the green colour variety of the Beryl family of minerals that includes Aquamarine (blue), Bixbite (red), Goshenite (colourless), Heliodor (yellow), Morganite (pink) and Pezzottaite (pink/red). Emerald gets its green colour from traces of chromium added to the basic Beryl formula. Emerald is found in many locations around the world. Probably the best known is the Muzo Mine in Columbia. This mine produced a 16,020 carat crystal! Emeralds from this location are generally considered the best colour for Emerald. Emerald was mined at Queen Cleopatras Ancient Egyptian emerald mine
