Green Amethyst
Green Amethyst is a green variety of quartz, a silicate mineral chemically referred to as silicon dioxide. The stone has its own very specific composition and is classified as a prasiolite. Since 1950, almost all natural prasiolite has come from a small Brazilian mine. Even to this day, the only mine that produces naturally forming prasiolite is in Brazil. But that location is almost completely mined out, making this variety of quartz one of the most rare. However, this green hue can also be obtained from a combination of heat treatment and ionizing radiation on purple quartz Amethyst. The Green Amethyst gemstone is believed to strengthen the will as well as the mind, protect from intoxication, attract prosperity as well as good fortune.
