Green jade cabochon ring

Possibly jadeite (NaAlSi₂O₆) or nephrite (Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂); the image is insufficient to distinguish them

AI-generated identification · may be incorrect

Translucent-to-opaque pale green cabochon with a polished, waxy-to-greasy luster; jade has hardness about 6–7 Mohs (jadeite) or 6–6.5 (nephrite). Both have interlocking crystal aggregates rather than a single crystal; the ring setting obscures diagnostic features.

Physical properties

Translucent-to-opaque pale green cabochon with a polished, waxy-to-greasy luster; jade has hardness about 6–7 Mohs (jadeite) or 6–6.5 (nephrite). Both have interlocking crystal aggregates rather than a single crystal; the ring setting obscures diagnostic features.

Formation & geological history

Jade forms through metamorphic and metasomatic processes, commonly in high-pressure or fluid-rich settings. Its age varies widely with the host rocks and deposit; the stone’s specific origin cannot be determined from the image.

Uses & applications

Used in jewelry, carvings, and ornamental objects; jade is also valued as a collectible gemstone.

Geological facts

“Jade” refers to two distinct minerals, jadeite and nephrite, which look similar but differ in composition and crystal structure.

Field identification & locations

The green color and cabochon cut are consistent with jade, but other green stones or imitations are possible; identification requires testing or gemological examination. Jade sources include Myanmar, China, Guatemala, and parts of western North America.
