Green faceted gemstone, likely synthetic glass or peridot

Indeterminate from image; possible peridot (olivine, (Mg,Fe)₂SiO₄) or green synthetic glass

AI-generated identification · may be incorrect

Bright transparent green, step/faceted rectangular cut, vitreous luster; apparent hardness cannot be determined visually. Peridot has Mohs hardness 6.5–7 and orthorhombic crystals; glass is amorphous and usually softer (~5–6).

AI Estimated Value

About $1–$20 if glass or synthetic; approximately $20–$200 for a small commercial peridot, potentially more if confirmed high quality.

Physical properties

Formation & geological history

Natural peridot forms in magnesium-rich igneous rocks and mantle-derived basalts, commonly from the Cenozoic; synthetic glass is manufactured and has no geological age.

Uses & applications

Peridot is used in jewelry; similarly colored glass or synthetic stones are inexpensive decorative substitutes.

Geological facts

The image alone cannot reliably separate peridot from green glass, tourmaline, emerald, or synthetic material. Refractometer, inclusions, birefringence, and hardness testing are needed.

Field identification & locations

Possible natural sources include Arizona, Pakistan, Myanmar, Egypt, and China. Inspect for bubbles (glass), characteristic “lily-pad” inclusions (peridot), and test specific gravity or refractive index with proper gemological tools.
