Peridot is one of the few gemstones that occur in only one color: olive green. However, the intensity and tint of the green depends on how much iron is present in the crystal structure, so the color of individual peridot gems in peridot fine jewelry can vary from yellow- to olive- to brownish-green. The most valued color is a dark olive-green.
Peridot, such as the beautiful stones in peridot fine jewelry, has a particularly violent origin. Olivine, of which peridot is a type, is believed to be one of the main components of the earth’s mantle. The rare gemstones are carried to the surface by volcanic activity. Peridot has also been found in meteorites.
Peridot fine jewelry is thought to bring the wearer good luck, peace, and success. Its powers include health, protection and sleep. Peridot is said to attract love and calm anger while soothing nerves and dispelling negative emotions.
