Physical properties

Small polished, opaque-to-translucent green cabochon with a vitreous-to-waxy luster. Jadeite has Mohs hardness 6.5–7; nephrite 6–6.5; the image is insufficient to distinguish either from other green stones or glass.

Formation & geological history

If genuine jade, it formed through metamorphic processes: jadeite commonly in high-pressure subduction-zone rocks, and nephrite in metamorphic or metasomatic settings. Geological age depends on the source deposit; the pendant’s origin cannot be determined visually.

Uses & applications

Small jewelry pendant; jade is also valued for carvings, beads, and cultural artifacts.

Geological facts

Jade is a trade term for two distinct minerals, jadeite and nephrite, not a single mineral species.
