The Beryl Group of minerals includes Aquamarine (blue), Bixbite (red), Emerald (green), Goshenite (colorless), Heliodor (yellow), Morganite (pink) and recently, Pezzottaite (pink to red). These gems are related by their chemical formulas and crystallography. Trace elements such as manganese (red) and chromium (green) added to the basic Beryl chemistry change the colors of the minerals. The name Beryl is from ancient Greek word beryllos, original significance unknown.
