Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities. A trace of iron in citrine’s structure is responsible for its yellow-to-orange color. Citrine was first appreciated as a golden-yellow gemstone in Greece between 300 and 150 BC, during the Hellenistic Age. Natural citrines are rare; most commercial citrines are heat-treated amethysts or smoky quartzes. Along with topaz, citrine is a birthstone for November. It’s also recognized as the gem that commemorates the thirteenth anniversary. Brazil is the leading producer of citrine, with much of its production coming from the state of Rio Grande do Sul. The name is derived from the Latin word citrina which means "yellow" and is also the origin of the word "citron". Sometimes citrine and amethyst can be found together in the same crystal, which is then referred to as ametrine.Citrine has been referred to as the "merchant's stone" or "money stone", due to a superstition that it would bring prosperity.

But, "It" comes from above."
