(or vermarine) is the name for any quartz crystal or cluster that is green in color.
Although often cut as a gemstone, prasiolite is actually quite rare in nature.
Most prasiolites on the market are heat treated amethyst.
These stones are sometimes called "Green Amethyst", possibly because
amethyst is the starting variety, or possibly just because it sounds
more valuable that way. When heat treated, the amethyst from most locations transforms into yellow or orange citrine. From a few locations, a green color results.
These locations include Montezuma, Brazil, and Arizona. Naturally occurring
prasiolite has been reported from Poland.
Prasiolite (sometimes spelled

example of quartz over prasiolite.

Other varieties that form macroscopic (large enough to see) crystals are as follows:
