description Peridot Overview
Peridot is the gem-quality form of olivine, a mineral whose green color comes mainly from iron in its crystal structure. Unlike many gemstones, its color is intrinsic to the material rather than primarily caused by trace impurities. Peridot occurs in igneous rocks and has also been identified in some meteorites; important sources include Arizona, Pakistan, Myanmar, and the Red Sea island of Zabargad. It is the birthstone associated with August.
