Prasiolite
Prasiolite is also known as Green Amethyst.
Prasiolite is the name for quartz that is green in color. It is quite rare in nature. Most Prasiolites on the market are heat treated Amethyst, and are sometimes called "Green Amethyst", possibly because Amethyst is the starting variety. When heat treated, Amethyst from most locations turns into yellow or orange citrine color. From a few locations, including Montezuma, Brazil, and Arizona a green color results. Natural Prasiolite has been reported from Poland.
