Citrine

Citrine is a variety of quartz known for its yellow to orange-brown colouration. This colour comes from traces of iron. Citrine forms in igneous, metamorphic, and sedimentary rocks, but most commercial citrine is heat-treated amethyst or smoky quartz. Natural citrine is rare and is found in Brazil, Spain, Madagascar, Mexico, and the U.S. (Colorado, North Carolina).
