Citrine is a yellow to brownish-yellow variety of quartz, which is a mineral composed of silicon and oxygen atoms. It is one of the most popular and affordable gemstones, often used in jewelry due to its beauty and affordability. Citrine is also known for its unique metaphysical properties, believed to promote creativity, wealth, and abundance. Natural citrine is relatively rare and is typically found in Brazil, Madagascar, and Zambia. However, most of the citrine in the market is actually heat-treated amethyst or smoky quartz, which changes the color to a yellow or brownish-yellow hue. Citrine has a long history of use in jewelry and as a decorative gemstone. It is also associated with various cultural and spiritual beliefs, including those of ancient Greeks and Romans, who believed that citrine was a symbol of prosperity and happiness.
