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.
Beryllium, aluminum, silicon and oxygen crystallize out of the felsic magma to form the mineral beryl. Emeralds happen when enough chromium, vanadium and iron have dissolved out of mafic rocks to give those beryl crystals a deep rich green color. Synthetic emeralds. Natural emerald formation is a wonderful but messy process.
