Heating certain Amethyst will turn them green. The heat treated product is then referred to as Green Amethyst, Amegreen or Vermarine& sometimes passed off as the natural green Quartz Prasiolite. Amethyst usually turns yellow, orange, or brown when heated. But some will turn green when heat treated.
This reaction is due to the formation of Iron oxides. Iron compounds with Fe3+ ions are often yellow or orange, alternately Fe2+ compounds are green. It is theorised that reducing environments not oxidizing zones lead to the formation of Amethyst that turns green once heated or to the direct natural growth of Prasiolite.
Green Amethyst & Prasiolite are often confused with the very similar in colour Praseolite which is created by heat treating Iolite.
Some Green Amethyst on the market is synthetic Quartz constructed by hydrothermal methods. Usually it is a vivid mint-green or blue-green instead of the paler golden-green of Prasiolite & heated Amethyst.
