Beautiful turquoise is a phosphate mineral popular all over the world. Mined since 5000 BC, it is one of the first gemstones known to be used by humans. Color variation from sky-blue to medium green is affected by differing amounts of copper and iron, more copper giving the stone a bluer color and more iron a greener one. Beautiful light blue turquoise is mined in Northern Iran and other varieties occur in Mexico, the United States and elsewhere.
