The pale green peridot is best known as the birthstone for August. Known also as chrysolite--or olivine in its raw natural form--the peridot once adorned ancient Egyptian royalty, and has been both found and worn around the world ever since. You'll most often find peridot in areas of high volcanic activity, and in Hawaii the peridot symbolizes the tears of fire and volcano goddess Hele.
Peridot is comparable to quartz in durability, ranking a 7 on the Mohs hardness scale. While tough enough for normal wear, care should be taken to protect your peridot jewelry from chips or scratches, ideally in a bezel or secure prong setting. Notably, peridot is sensitive to temperature changes, and as such should not be ultrasonically or steam-cleaned. Mild soap and water with a soft cloth is recommended for cleaning.
