Citrine Brazil rainbow with gentle patterns made upCitrine is a variety of quartz whose color ranges from a pale yellow to brown due to a range of ferric (iron) impurities. Natural citrine is rare, but can be manmade. Like citrus, citrine shares its name's origin with the Latin word for yellow, citrinia. Throughout history and even today citrine is associated with prosperity and as such occasionally has the nickname, merchant's stone. Notable regions: Brazil This item is 4. 5" x 3. 25" and weighs 16.
