Gemstones - Background and Lore - Citrine


Citrine is one of the November birthstones. Topaz is the other. Citrine is a quartz variety. It gets it's name from the Latin word citrus, meaning "citron" (a fruit closely related to the lemon). Citrine comes in a wide range of sizes. Most citrine is found in traditional rounds and fancy shapes, but it is also available in more contemporary cuts and carvings. Before the development of modern gemology, citrine was often confused for topaz. Citrine is found in Bolivia, Brazil, and Spain. It is a 7 on the Mohs Scale of Hardness and has good toughness. High heat can cause color loss. Sudden or extreme temperature change can cause fracturing. Citrine is soluble in hydrofluoric acid and ammonium fluoride. It is slightly soluble in alkalis. Citrine is routinely heated to produce the desired color. Often it is produced by heating amethyst. This treatment is undetectable and assumed. Ultrasonic cleaning is usually safe. Steam cleaning is not recommended. The safest cleaning method is warm soapy water and a toothbrush. Alternatives include amber, carnelian, chrysoberyl, Malaya garnet, sapphire, smoky quartz, spessartite garnet, topaz, and tourmaline. Citrine is believed to help the heart, kidney, digestive tract, liver and muscles. It promotes creativity, helps personal clarity and eliminates self-destructive tendencies.
