Green cabochon gemstone, likely glass-filled or synthetic emerald imitation

Uncertain; possible synthetic emerald (beryl, Be₃Al₂Si₆O₁₈) or green glass

AI-generated identification · may be incorrect

Vivid translucent green, glassy luster, rounded cabochon cut, and numerous internal bubbles/fractures. Natural emerald has Mohs hardness 7.5–8 and hexagonal beryl crystals; visible round bubbles strongly suggest glass or a heavily treated synthetic material rather than natural emerald.

AI Estimated Value

About $1–$20 if glass or imitation; $20–$200 if a commercial synthetic emerald; natural emerald value requires laboratory confirmation and may range from hundreds to many thousands of dollars.

Physical properties

Formation & geological history

If emerald, it formed in hydrothermal veins millions to billions of years ago; notable deposits include Colombia, Zambia, Brazil, and Afghanistan. The pictured object appears polished and mounted or displayed, so its manufacturing history is not geological.

Uses & applications

Used as costume jewelry, decorative material, or an emerald imitation; genuine emerald is used in fine jewelry. Green glass has little industrial or collector value.

Geological facts

Bright green fluorescence-like glow can result from strong transmitted light and does not prove emerald. Gas bubbles are a key clue for glass; refractive-index and spectroscopy testing are needed for confirmation.

Field identification & locations

Check with a loupe for spherical bubbles, molded flow lines, and uniform color; test hardness only on an inconspicuous area, since glass and emerald differ. A gemologist should measure refractive index and inspect inclusions.
