Used in jewelry and other finery since ancient times, turquoise occurs when copper sulfides and aluminum oxidize and weather, forming the lovely blue green gemstone. Its name is derived from the nation of Turkey, where the first Turquoise is thought to have entered the European continent from the east. In North America, it is most commonly found in the deserts of the southwestern United States and Mexico.
