Carved jade pendant

Likely nephrite jade (tremolite–actinolite series); the pictured certificate appears to identify it as jade, but the exact material cannot be confirmed from the image

AI-generated identification · may be incorrect

Green, polished and intricately carved, with a waxy-to-greasy luster. Nephrite has Mohs hardness 6–6.5, a tough, interlocking fibrous crystal structure, and specific gravity around 2.9–3.1; jadeite is a possible alternative with different properties.

Physical properties

Green, polished and intricately carved, with a waxy-to-greasy luster. Nephrite has Mohs hardness 6–6.5, a tough, interlocking fibrous crystal structure, and specific gravity around 2.9–3.1; jadeite is a possible alternative with different properties.

Formation & geological history

Jade forms through metamorphic processes, commonly in subduction-related settings; its age depends on the deposit and cannot be determined from this pendant. Nephrite commonly occurs in metamorphosed ultramafic rocks and associated serpentinites.

Uses & applications

Used for jewelry, ornaments, and carved art. The pendant’s value depends on verified jade type, color, translucency, workmanship, and provenance.

Geological facts

The certificate shown gives a weight of about 32.66 g, but its text and authenticity are not independently verifiable from the image.

Field identification & locations

Jade is commonly sourced from China, Myanmar, Canada, and other regions. Field identification requires gemological testing; visual appearance alone cannot reliably distinguish nephrite, jadeite, and imitations.
