Peridot, the volcanic gem, is the gem variety of the mineral olivine. Peridot forms as crystals within certain rare types of basaltic lava flows and has even been found within pallasite meteorites from outer space.
Pakistan is recognized for producing some of the finest quality peridot in the world with a bright, intense bluish yellow green color and large clean stones. The production of rough peridot from Pakistan has slowed considerably in recent years with fine material increasingly expensive and difficult to obtain. Peridot is the traditional gemstone for people born in the month of August.
