Personal Note From Natural Gems Belgium:

Prasiolite , also known as green quartz, green amethyst or vermarine  is a green variety of quartz. As purple Amethyst is also a variety of quartz. Since the commercial name is green amethyst, we place it in the Amethyst gemstones. Most prasiolite sold is used in jewellery settings, where it can substitute for far more expensive precious gemstones. Artificial prasiolite is produced by heat treatment of amethyst because some amethyst will turn green when treated. Currently, almost all prasiolite on the market results from a combination of heat treatment and ionizing radiation. This specific gemstone is heat treated Amethyst that is not radiated. It is haxagonal from shape and has a well cut snowflake cut, different hues of green, and its symmetry is good to very good , its polish is good. The luster is very good.
