The most sought after peridot today comes from the San Carlos Reservation in Arizona. These gemstones have a lime green color and are found on the Peridot Mesa least of Gila County. Mining of the gemstone is done by the Native Americans and their families. The gemstones found on the Peridot Mesa began as a volcanic eruption millions of years ago. Ash and molten rock were left behind after the volcano erupted. Many of the stones are found as crystals hardened within the volcanic ash.
