Physical properties
Hardness of 6.5-7 on the Mohs scale, olive green to yellowish-green color, vitreous luster, orthorhombic crystal system, conchoidal fracture, specific gravity of 3.2-4.3
Formation & geological history
Formed in the Earth's mantle under high-temperature conditions and brought to the surface by volcanic activity or tectonic movement; also found in some pallasite meteorites.
Uses & applications
Used primarily in fine jewelry, rings, earrings, and necklaces, as well as mineral collecting.
Geological facts
Peridot is one of the few gemstones that occurs in only one color (green), and some peridot crystals come from outer space, originating in meteorites.
Field identification & locations
Found in regions with volcanic activity and peridotite deposits, such as Arizona, Pakistan, Myanmar, and China. Identified by its characteristic olive-green color and double refraction.
