Peridot is a lime-green-to-olive gemstone often worn in the form of necklaces and earrings. It is created from volcanic eruptions and is sometimes even found on meteors that have fallen to earth.
Its color is dependent on its body size, so the smaller stones cannot produce the intense greens for which the the larger ones are especially prized. It is the state gemstone of Nevada and has a hardness rating of 6.5 on the Mohs scale.
Peridot is a fairly soft gem and is susceptible to attack by acids, which can quickly remove the polish from its surface. Peridot is a symbol of fame, dignity, and protection, and it is used to transform dreams into reality.
When set in gold, it also protects its wearer from terrors of the night. Legend has it that pirates favored peridot to protect them against evil. Peridot is the anniversary gemstone for the 16th year of marriage.
As with all gems, protect peridot from scratches, and sharp blows. Also, avoid large temperature changes (such as those that would result in leaving it near a heater vent or in a hot car). Do not clean peridot in a home ultrasonic cleaner.
