Citrine, also called citrine fortz is a variety of quartz. It ranges in color from a pale yellow to brown. Citrine has ferric impurities, and is rarely found naturally. Most commercial citrine is in fact artificially heated amethyst or smoky quartz. Brazil is the leading producer of naturally mined citrine, with much of its production coming from the state of Rio Grande do Sul.
In ancient times, citrine was carried as a protection against snake venom and evil thoughts.
Citrine is one of three traditional birthstones for the month of November.
It is nearly impossible to tell cut citrine from yellow Topaz visibly.
