Goshenite, Be3Al2Si6O18, is the colorless variety of beryl and is named after the site where it was first discovered, Goshen in Massachusetts. It is sometimes called "mother of gemstones." The impurities in Goshenite create all the popular beryls like emeralds (green beryl), heliodor (yellow beryl), morganite (pink beryl) and aquamarine (blue beryl). The base elements found in this stone are Beryllium, Aluminum and Silicon.
Goshenite occurs in North and South of America, particularly in Colombia, Northern Europe, East and South Africa, and the Himalayan regions of Asia. The hardness on Mohs scale of the stone is 7.5 - 8, the refractive index is 1.57 - 1.60 and the specific gravity is 2.6 - 2.8. Goshenite has a hexagonal crystal system.
