What is "citrine"?

Citrine is a type of quartz that ranges in color from pale yellow to brownish orange. It is often used as a gemstone in jewelry due to its bright and sunny appearance. Citrine is formed when amethyst, another type of quartz, is exposed to heat and changes color. Its name is derived from the French word for lemon, "citron," because of its lemon-yellow hue. Citrine is believed to have healing properties, including promoting prosperity and success, and is sometimes referred to as the "merchant's stone" or the "success stone." It is also the birthstone for November.
