One of the two traditional birthstones for November, citrine is also known as citrine quartz and citrine topaz, as it ranges from yellow to brown. In some ancient cultures, it was believed that citrine was used to protect people from evil thoughts and snake venom. Citrine is a form of quartz with ferric iron impurities, and is rarely found naturally because it needs to be artificially heated to achieve the gem used in jewelry. While all citrine is individually gorgeous, most favor the darker "sherry"-colored variety.


Citrine is found predominantly in Brazilian mines, with much of its production coming from the state of Rio Grande do Sul.


Citrine can be easily scratched. Citrine often permanently changes color if left in the sunlight for several hours.
