Small pale-green tumbled stone, possibly serpentine or aventurine

Undetermined from the image; possible serpentine-group minerals or quartz with fuchsite (aventurine)

AI-generated identification · may be incorrect

A small, rounded, pale green-gray specimen with a smooth surface and subdued luster. Hardness and crystal structure cannot be determined reliably from the image; serpentine is Mohs 2.5–5.5, while aventurine quartz is about 7.

Physical properties

Formation & geological history

If serpentine, it formed through hydrothermal alteration of magnesium-rich rocks; if aventurine, it formed as quartz with green mica inclusions. Geological age and source cannot be established visually.

Uses & applications

Likely a tumbled or otherwise shaped specimen for collecting or jewelry; identification is needed before assigning other uses.

Geological facts

Its small size and uniform pale color make visual identification uncertain; a hardness or mineral test would help distinguish candidates.

Field identification & locations

The image shows a smooth, elongated pebble, but lacks diagnostic features such as visible inclusions or cleavage. Similar green stones occur in many regions; estimated value is about $1–$10 if it is a common tumbled stone.
