golden Citrine 

Properties:
     Citrine is the yellow to gold to orange color of quartz. Its name comes from the French for lemon, citron, though citron tends to be more golden than lemon yellow. Since quartz is an abundant mineral, the gem-quality specimens typically have very good luster and excellent clarity. 

Many commercial-grade citrines in the market have been produced by heat treating amethyst, which will turn yellow at relatively low temperatures (around 470 degrees centigrade) and dark-yellow to red-brown at higher temperatures (around 1000 degrees centigrade). Virtually all heat-treated citrines have a reddish tint. Deposits of natural-colored citrine are found principally in Brazil and Madagascar, as well as in Burma, the USA and Namibia. Citrine's sunny color has made it a gem thought to radiate positive energy. Citrine is known as the "success stone" because it is thought to promote success, prosperity, and abundance, especially in business. The practice of placing a citrine in the cash register of a shop earned it the nickname "merchant's stone."   Emotionally, citrine relieves depression, self-doubt, anger, and irrational mood swings. Citrine is a stone that brings happiness and cheer to one who carries or wears it. Citrine also reduces self-destructive tendencies. Citrine can helps eliminate fears and can help one overcome emotional trauma and grief. Sensuality and sexuality can also be heightened by citrine.
