Peridot owes its green color to the iron in its composition. Varying in depth depending on the amount of iron, its shades range from yellow green, through olive green, to brown. This fine stone was widely used in Ancient Egypt and in the Middle Ages on cult objects. Highly prized by jewelers, it also met with great success during the Baroque period.
One of the largest peridot mines has been operated on Zabargad Island in the Red Sea for 3,500 years. The stone is also sourced from deposits in Pakistan, Myanmar, Tanzania, and the United States.
Peridot presents a hardness of 6.5 to 7 on the Mohs scale.
