Prasiolite is a yellow-green to green variety ofĀ quartzĀ that is cut into faceted stones for use in jewelry or purchased byĀ gemstoneĀ collectors. It is produced by the three processes described below:

Heat-Treated Amethyst:Ā Most prasiolite is produced by heating naturalĀ amethystĀ in a laboratory oven to about 500 degrees Celsius. This heating changes the amethyst's color from purple to green or yellowish green.Ā 

Irradiated Amethyst:Ā A small amount of prasiolite is produced by irradiating natural amethyst. This produces prasiolite with a light green color. The green color is often unstable and can fade to colorless if the stone is exposed to temperatures over about 150 degrees Celsius.

Naturally Heated Amethyst:Ā Another small amount of amethyst is heated by natural processes. It is found where an amethyst-bearing rock unit has been heated by younger lava flows or nearby intrusions.
