Physical properties

Small, rounded, opaque dark-green specimen with a smooth, polished surface. Hardness, luster, crystal structure, and specific gravity cannot be reliably determined from the image.

Formation & geological history

If natural stone, it formed through geological mineralization and was later shaped and polished; age and formation environment are unknown.

Uses & applications

Likely a decorative or collecting piece; value depends on confirmed identification, size, and quality.

Geological facts

Green color alone is not diagnostic: serpentine, jade, and several other minerals can look similar.

Field identification & locations

A clearer close-up and simple tests—especially hardness and streak—are needed for field identification. Green ornamental stones occur in many regions worldwide.
