Peridot is mined in Arizona in the U.S., Myanmar (formerly Burma) China, Sri Lanka, Pakistan, Norway, the Ural Mountains of Russia and Germany. The finest Peridot comes from St. Johns Island (Zebirget) in the Red Sea off Egypt. But new sources in Pakistan are challenging that claim with some exceptional specimens. Although peridot is distinctly a different shade of green, many jewelers refer to peridot as "evening emerald". Emerald is a dark green as opposed to a yellow green and always contains inclusions. Peridot has been mined as a gemstone for an estimated four thousand years. It is the gem variety of Olivine.
