Tumbled jade-like stone, likely jadeite or nephrite

Jadeite (NaAlSi₂O₆) or nephrite, a fibrous amphibole aggregate

AI-generated identification · may be incorrect

White to pale gray, opaque, with dark green mineral veining; waxy to subdued vitreous luster and no visible crystals. Hardness is approximately 6–7 Mohs; very tough, dense, and typically lacks obvious cleavage.

Physical properties

Formation & geological history

Jadeite forms in high-pressure, low-temperature subduction-zone metamorphic rocks, while nephrite forms through metamorphic alteration of ultramafic or carbonate rocks. Geological ages vary widely by deposit.

Uses & applications

Used for carvings, beads, cabochons, ornaments, and historically tools; quality depends strongly on translucency, color, texture, and verified identity.

Geological facts

White jade varieties with green veining are commonly sold as jade, but similar-looking serpentine, quartzite, and dyed stones are widespread. Laboratory testing is often required for confident identification.

Field identification & locations

Common sources include Myanmar, Guatemala, China, New Zealand, Canada, and Russia. Scratch resistance, exceptional toughness, compact texture, and specific gravity testing help distinguish jade from softer imitations.
