Beryl Be3Al2SiO6
In the picture above is an example of emerald, a variation of beryl. The light green form of Beryl is not recognized as Emerald, but rather Green Beryl. The deep color of Emerald is caused by traces of the element chromium, but sometimes also vanadium. Emerald often crystallizes in perfect, six-sided hexagons. Crystals are usually as individual prismatic hexagons.Click for more info for more on emeralds
