Citrine is one of the accepted birthstones for November, as well as the suggested anniversary gemstone for the 13th year of marriage. People once carded citdne as a protective talisman against the plague, bad skin and evil thoughts. To clean, immerse in a jewelry cleaner or in lukewarm soapy water and use a small bristle brush. Care should be taken to protect it from scratches and sharp blows. When mined, citrines were either amethysts or other quartz family members.
Citrine is found mainly in Brazil.
