CITRINE

Citrine quartz is a popular, gem-quality yellow, golden or orange colored quartz, which draws its distinctive color from traces of iron and its name from the French for lemon; citron, though this gem tends to be more golden than lemon yellow. Quartz is an abundant mineral; therefore, this gem is an affordable gem type, even in large sizes.

Since citrine quartz tends to be more popular than amethyst quartz, some of the commercial-grade these gemstones on the market have been produced by heat-treating amethyst, which will turn yellow at relatively low temperatures (around 470 degrees centigrade) and dark-yellow to red-brown at higher temperatures (around 1000 degrees centigrade). This is a stable and permanent procedure that is disclosed by all reputable gemstone suppliers. While it is difficult to tell whether citrine has been heated or not, virtually all heat-treated one has a reddish tint.

This gem has a lot of common with amethyst another mineral of quartz with microcrystal structure. The only difference between this gem and amethyst is about oxidation of iron ion at these two minerals which at appears at colorless crystal of quartz. When you heat quartz, you release iron ion and make the purple pink of amethyst to gold or orang. Ametrine is a natural sample of combination of gold citrine and purple amethyst which gather at a gem stone.

Citrine is found all over the world, with commercial deposits coming from countries as diverse as Brazil, The United States, Burma, Namibia, Bolivia and Madagascar.
