About Peridot by Emylee Peridot is the extraterrestrial gem: tiny peridot crystals have been discovered in meteors that fall to earth. On our planet, this lime-green gem forms in volcanoes, under tremendous heat and pressure. Peridot is treasured in Hawaii as the goddess Pele's tears. The island of Oahu even has beaches made out of tiny grains of peridot. Today most peridot is mined, often by hand, by Native Americans on the San Carlos Reservation in Arizona. The fresh yellowish-green of Gemvara's peridot is its distinctive signature. The color of most gems is caused by traces of other elements but the color of peridot is an integral part of its structure.

The ancient Romans called peridot "evening emerald," since its green color did not darken at night but was still visible by lamplight. Peridot was mined in ancient Egypt on an island called Zeberget.

Because peridot is sensitive to rapid changes in temperature, never have it steam cleaned and avoid ultrasonic cleaners.
