Prasiolite, also known as Green Amethyst, is a rare silicon dioxide mineral and member of the Quartz family. It crystallizes in mass and fibrous formations, with the color green coming from inclusions of Iron. Prasiolite was first discovered in the early 1800’s in Silesia, Poland. The name “Prasiolite'' was given after the Greek word meaning “leek” (in reference to its color). Since then, nearly all of the Prasiolite on the market comes out of the Minas Gerais region of Brazil. The colors from this region can range from translucent to a dark green. This depends on the impurity level within the chemical body.
