Peridot is gem-quality olivine, which is a silicate mineral. Peridot is one of the few gemstones that occur in only one color: an olive-green. While olivine is an abundant mineral, gem-quality Peridot is quite rare because it is chemically unstable on the Earth’s surface. It is mined in Arkansas, Arizona, New Mexico, Australia, Brazil, South Africa, Sri Lanka, and Tanzania to list a few. Peridot has been valued for thousands of years as a semi-precious healing stone. It is a high-vibrational Heart Chakra crystal that carries a positive energy, especially helpful for those undergoing stressful emotional situations. It is the stone for Archangel Raphael and rules the realm of Angelic Virtues. Peridot has the ability to bring out unconditional love, happiness and light.
