Carved greenstone figure

Likely nephrite jade (jadeite is a possible alternative), mainly amphibole-group minerals

AI-generated identification · may be incorrect

Opaque dark green, waxy to vitreous luster, polished and carved; nephrite hardness ~6–6.5 Mohs, jadeite ~6.5–7, with tough fibrous/interlocking texture and no obvious cleavage. The surface pits and pale flecks may reflect natural inclusions or weathering.

AI Estimated Value

Approximately $20–$150 if common greenstone or serpentine; roughly $100–$1,000+ if authenticated nephrite with attractive carving and provenance.

Physical properties

Formation & geological history

Likely formed by metamorphism and metasomatism in high-pressure, fluid-rich zones; jade deposits are commonly Mesozoic to younger, though the carving’s age cannot be determined from the image. This is a human-worked geological specimen, not a natural rock shape.

Uses & applications

Used historically for tools, ornaments, ritual objects, and sculpture; today it is primarily decorative and collectible. Value depends strongly on confirmed jade identity, carving quality, provenance, and condition.

Geological facts

Nephrite is calcium-magnesium amphibole, chiefly tremolite–actinolite; jadeite is sodium-aluminum pyroxene. Both are prized for exceptional toughness rather than exceptional hardness.

Field identification & locations

Common sources include China, British Columbia, Siberia, Wyoming, Myanmar, and Guatemala. Verify with specific gravity, refractive index, and laboratory testing; glass or serpentine imitations are common.
