Citrine is the yellow to golden variety of the quartz mineral group. Its name comes from the Latin word citrus, meaning “lemon.” It is the birthstone option for November and a 13th wedding anniversary gift. Citrine is mostly found in Brazil, Madagascar, Russia, US, Spain, and France, to name a few. Legend has it that citrine promotes concentration and higher intelligence. In fact, some Chinese students bring citrine to school every day to help with their schoolwork and exams. In the Middle Ages, soldiers wore this gem on their chests believing it would protect them during battle.
