Beryl, the mineral of which emerald is a variety, has a chemical composition of Be 3 Al 2 (SiO 3) 6. When pure, beryl is colorless and known as goshenite.. Trace amounts of chromium or vanadium in the mineral cause it to develop a green color.
Some Emeralds are light green or even have a tinge of yellow. Emeralds are made from beryl and include the rare element beryllium. While beryl is a common form of mineral, emeralds are usually very rare. The two trace elements that give an Emerald its beautiful green are chromium and vanadium.
