| Citrine is one of the most affordable gemstones. Named after the French word for lemon, "citron", many citrines have a juicy lemon color. Citrine includes yellow to gold to orange brown shades of transparent quartz. In ancient times, citrine was carried as a protection against snake venom and evil thoughts. Natural citrines are rare. Most of the traded citrines are heat-treated amethysts or smoky quartzes. Since most citrine on the market started its life as amethyst, which was heated to turn its color to lemony yellow, citrine jewelry, as well as amethyst jewelry, should be kept away from prolonged exposure to strong light or heat. With this precaution, citrine jewelry will last for many generations.
