Citrine is a yellow to golden-brown variety of quartz, known for its warm, sunny color that can range from pale yellow to deep amber. Its vibrant hue is caused by the presence of iron and other trace elements during its formation. Citrine is often associated with positivity, abundance, and prosperity, making it a popular choice for those seeking to attract wealth and success. In terms of durability, citrine has a hardness of 7 on the Mohs scale, which makes it suitable for everyday wear in jewelry. It is commonly found in Brazil, Madagascar, and the United States. Citrine is also sometimes referred to as the "Merchant's Stone" due to its believed ability to bring good fortune in business.
