The Arizona mines in the United States are currently one of the major producers of commercial quality Peridot. Highly prized, both locally and abroad, the bright green to yellow-green Peridot is used both as a faceted and tumbled gemstones.

Mesa Peridot occurs as individual grains and aggregates of grains in basalt, which is about 3 to 35 meters thick. The Peridot from the Mesa is recovered by drilling and blasting, and also recovered after having been weathered out of the basalt, in the gullies and canyons which lead down the sides of the Mesa.

The Peridot grains are typically 6 to 13 millimeters in size. The faceted gems are quite small and are generally about 1 carat in size; although 2 to 3 Carat flawless Peridots are not uncommon, gems over 5 carats and over are unusual.
