 Citrine is a yellow transparent quartz.
 Natural citrine is rarely found and is mostly pale yellow with mild pleochroism. The natural color of citrine can vary from yellow-green to orange and brown-orange. Clear amber stones are especially valued. Citrine forms part of a unique gemstone - amethrin, which is found in Bolivia.
 The most beautiful natural citrine crystals are found in Brazil. Citrine 
 is also produced in Argentina, Burma, other Brazilian states, France, Madagascar, Russia (Urals), Spain, and the United States.
 In ancient times, citrine was considered a mascot that protects against poison and evil thoughts. Citrineis used in healing to give sensitive people inner strength to solve metabolic problems. Citrine is also one of the two stones in the November horoscope.
