Carved translucent jade pendant

Likely nephrite jade (actinolite–tremolite series); possibly jadeite or chalcedony, identification requires testing

AI-generated identification · may be incorrect

Pale gray-white, translucent, waxy to vitreous luster, and intricately carved. Jade hardness is about 6–6.5 Mohs, tough, fine-grained, with no obvious cleavage; the pendant and metal loop are human-shaped/processed geological material.

Physical properties

Pale gray-white, translucent, waxy to vitreous luster, and intricately carved. Jade hardness is about 6–6.5 Mohs, tough, fine-grained, with no obvious cleavage; the pendant and metal loop are human-shaped/processed geological material.

Formation & geological history

Nephrite forms through metamorphism and metasomatism in ultramafic or carbonate-related rocks; jadeite forms in subduction-zone settings. Geological ages vary widely; common sources include China, Myanmar, Canada, New Zealand, and Russia.

Uses & applications

Used for jewelry, carvings, ceremonial objects, and ornaments. Value depends strongly on confirmed jade identity, translucency, color, craftsmanship, and lack of treatments.

Geological facts

The smooth, fibrous toughness of true jade allows detailed carving without easy breakage. White “mutton-fat” nephrite is especially associated with high-quality Chinese jade carving.

Field identification & locations

Check density, cool feel, toughness, and a refractive index/specific-gravity test; a gemological lab can distinguish nephrite from jadeite, quartz, glass, or resin. Visible bubbles, uniform plastic-like appearance, or very low density suggest an imitation.
