About Prasiolite

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

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

Naturally Heated Amethyst: 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.

Facts:

  • Mohs Hardness: 7
  • Mineral: Quartz
