Turquoise Knotted Necklace

Turquoise is a stone used in ancient jewelry and artifacts, having been mined since at least 6000 BC by early Egyptians it has been in fashion ever since. The name comes from a French word, "turquoise" which means Turkish, from which country Persian material passed on its way to Europe. Turquoise is a secondary mineral of copper found often in the weathered zone of a copper deposit. The finest turquoise comes from Iran, but beautiful specimens are also found in the southern US.
