Chrysoberyl

Chrysoberyl is a rare mineral that occurs in granitic rocks and pegmatites and in mica schists. Used as a gemstone, the varieties, alexandrite and cat's eye, are highly prized. The name comes from the Greek meaning “golden” and beryl, in allusion to the color. It was discovered in Brazil in 1789.
