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.
