About Green turquoise :-Green turquoise is indeed a rarity, but it can be found in a few areas around the world. Mongolia and Egypt's turquoise deposits are known to occur more green than blue. Mines from India are also known to produce green turquoise. China has some very desirable deposits, but much of China's turquoise is often enhanced. The United States is today's leading producer of green turquoise. It is very popular for inlay jewelry in the Southwestern USA. The most famous green turquoise comes from Nevada's Tonopah Blue Gem mine. The Tonopah Blue Gem mine is famed for lime green turquoise with golden colored rhyolite matrix.
