Gemstone of the Week: Citrine

(Image found on

Citrine is a gorgeous gemstone and one of the possible birthstones for November.  Citrine is the yellow to orange to brownish variety of Quartz and ranges from $2-$60 per carat.  Citrine is coloured by hydrous iron oxide and forms as hexagonal crystals.  Natural Citrine is actually quite uncommon compared to the other varieties of Quartz, however most of what is on the market is actually Amethyst or Smokey Quartz that has been heat-treated to look like Citrine.  Generally, Citrine will form  anywhere that Amethyst forms, and often is found combined in the same stone as Amethyst.  When this occurs if is known as Ametrine.    Gem-quality Citrine may be found in Russia, Scotland, India, France, Brazil, Spain, and the U.S. (specifically, in North Carolina).
