Peridot

Published: June 20, 2007

Types: Associated with light, peridot is a bright yellowish green color. The intensity of its color depends on the amount of iron present. Peridot is usually transparent, and may range from olive to brownish green.

History: Although peridot is the traditional birthstone for August, ancients believed it was a gift from nature to celebrate the arrival of spring. Historians believe that many royal emeralds (such as Cleopatra's) were actually peridot.

Origins: St. John's Island in the Red Sea is the first documented source of peridot. Currently, the United States (especially Arizona), China, Pakistan, and Myanmar (formerly Burma) are major sources.

Treatments: To improve appearance, common treatments include the addition of colorless oil, wax, or resin. Most peridot is treated in some way.

Availability: A strand of 4mm round beads starts around $3, making peridot an affordable gemstone. Components such as pendants or jeweled head pins set with peridot are also reasonably priced.

Care: Peridot is a relatively soft stone. Clean it with warm, soapy water, and avoid steam or ultrasonic cleaning.
