Peridot is a natural gemstone variety of the mineral olivine, prized for its fresh yellowish-green to olive-green color.
Its color is caused by iron in its chemical composition, making it one of the few gemstones whose color comes from its basic structure rather than impurities.
Peridot has a hardness of 6.5–7 on the Mohs scale, making it suitable for jewelry with proper care.
It has a vitreous (glassy) luster and is usually transparent with good brilliance.
Its refractive index ranges from 1.65 to 1.69, giving it a bright and lively appearance.
Peridot has a specific gravity of approximately 3.27–3.37.
It has poor cleavage but exhibits conchoidal to uneven fracture, so it should be protected from hard impacts.
A characteristic feature of peridot is its strong double refraction, which may cause doubling of facet edges when viewed through the stone.
High-quality peridot is eye-clean, although some stones may contain distinctive lily pad inclusions, which are considered a diagnostic feature.
Major sources of peridot include the Pakistan (especially the Suppat area), Myanmar, China, United States (Arizona), Vietnam, and Egypt.
