Citrine (Sunela) is a spectacular transparent crystalline quartz that ranges in color from yellow to reddish-orange, orangish-yellow, and brownish-orange. It is a substitute for Yellow sapphire (Pukhraj stone) and is most abundantly found in Madagascar, Brazil, Russia, and the U.S.A. It’s a November stone. The word citrine has a French origin, “citron,” which translates into “lemon” due to its color.
