Arizona’s reputation as a major source of peridot is closely tied to Peridot Mesa, a volcanic formation located in Gila County on the San Carlos Apache Indian Reservation. This mesa represents the most significant peridot-producing area in the United States and has been an important supplier of gem-quality olivine for international markets for many decades.

The peridot found at this site originates deep within the Earth’s mantle and was brought to the surface through ancient volcanic eruptions. As molten basalt rose and cooled, it trapped peridot crystals within solidified lava layers. These crystals are now found scattered throughout basalt flows as isolated grains and compact crystal groups. The volcanic layers vary in thickness, reflecting repeated eruptive events over long geological time periods.

Mining activities at Peridot Mesa are overseen exclusively by the San Carlos Apache Tribe, and public access is strictly regulated. A recreation permit is required for entry and can be obtained from the tribe’s Recreation and Wildlife Department located along Highway 70 east of Globe. Typical crystal sizes range from 6 to 13 millimeters, producing stones well-suited for faceting and fine jewelry. The nearby community of Peridot, Arizona, has long been supported by this gemstone industry, underscoring the economic and cultural importance of peridot mining to the region.
