Green cabochon gemstone, possibly peridot

Uncertain from the photo; possible gem-quality olivine, (Mg,Fe)₂SiO₄

AI-generated identification · may be incorrect

Oval, polished cabochon with translucent yellow-green color and vitreous luster. If peridot, hardness is 6.5–7 Mohs and the crystal system is orthorhombic; the image alone cannot confirm its identity or properties.

Physical properties

Formation & geological history

Natural peridot forms in magnesium-rich igneous rocks and mantle-derived volcanic material; gem deposits occur in places such as Arizona, Pakistan, and Myanmar. The pictured stone has been cut and polished, but its geological age and natural or synthetic status cannot be determined visually.

Uses & applications

Used in jewelry and as a collectible; value depends strongly on confirmed identity, naturalness, color, clarity, and weight.

Geological facts

Peridot is the gem variety of olivine, but other materials and imitations can have a similar green appearance.

Field identification & locations

A gemological test—especially refractive index and specific gravity—is needed for reliable identification; inspect for natural inclusions and ask for a certificate for valuable stones.
