Citrine is one of the most affordable gemstones. A transparent quartz named from the French for lemon, “citron", citrine has yellow to gold to orange brown shades.
In ancient times, citrine was worn as protection against snake venom and evil thoughts.
Sometimes citrine is referred to as topaz quartz, which is incorrect. This name was used in the past in reference to the color, which is sometimes similar to the color of topaz. Since topaz is a different mineral, the name topaz quartz can be confusing, and should not be used.
However, citrine is considered an alternative to topaz as the birthstone for November and the gemstone for the astrological sign of Sagittarius.
