Citrine, a member of the Quartz mineral family, is a Quartz whose color is probably caused by Iron traces. Citrine's name is derived from the French Citrine for lemon. In ancient times, citrine was said to have the power to ward off snakebite. Even more powerfully, the ancients believed citrine also protected against the venom of evil words and thoughts. Citrine is an alternate birthstone for November. Sources for this gemstone are Brazil, Bolivia, and Madagascar.
