Green cabochon pendant, likely jade

Probably nephrite jade (tremolite–actinolite, Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂); visual identification is uncertain

AI-generated identification · may be incorrect

Opaque, mottled dark-green polished cabochon with a waxy-to-greasy luster. Nephrite has Mohs hardness 6–6.5, a dense interlocking fibrous structure, and no prominent cleavage; the pendant’s metal setting is not geological material.

AI Estimated Value

Approximately $10–$100 for a modest pendant with an unverified stone; material, workmanship, and confirmed jade identity can substantially change value.

Physical properties

Formation & geological history

If nephrite, it formed through metamorphic processes, commonly in altered ultramafic rocks; jade deposits occur in rocks of varied ages. The image does not establish the stone’s locality or age.

Uses & applications

Jade is used for jewelry, carvings, and ornamental objects; this specimen is fashioned as a pendant.

Geological facts

Green stones sold as jade may also be jadeite, serpentine, or other materials; appearance alone cannot confirm identity.

Field identification & locations

The smooth, tough-looking green cabochon is consistent with jade, but confirmation requires tests such as refractive-index or specific-gravity measurement. Nephrite is found in places including British Columbia, Siberia, and New Zealand.
