Likely jade or green chalcedony cabochon

Possibly nephrite jade (actinolite–tremolite) or green chalcedony (microcrystalline quartz, SiO₂)

AI-generated identification · may be incorrect

Polished, translucent-to-opaque green cabochon with a vitreous-to-waxy luster; apparent hardness is roughly Mohs 6–7. The intense green illumination may be enhanced by backlighting, so color and identity cannot be confirmed from this image alone; no visible cleavage or crystal faces.

Physical properties

Formation & geological history

Nephrite forms in metamorphic rocks through fluid-assisted alteration, commonly in serpentinite zones; chalcedony forms from silica-rich fluids filling cavities and fractures. Their ages vary widely by deposit, from Precambrian to recent geological settings.

Uses & applications

Used for carved ornaments, beads, cabochons, jewelry, and decorative objects; jade generally commands more value than ordinary green chalcedony.

Geological facts

Natural jade typically has a fibrous, interlocking texture and a greasy luster, while chalcedony is more uniformly waxy and may show cloudy banding or inclusions. Strong fluorescence or glow can also indicate dye, resin, or another treated material.

Field identification & locations

Common sources include Myanmar, China, Canada, New Zealand, Russia, and the United States for jade, while green chalcedony occurs worldwide. Identification requires refractive index, specific gravity, magnification, and hardness testing; avoid scratching the polished surface.
