Tumbled pale-green stone, possibly serpentine
Unidentified green silicate; serpentine is a tentative visual match
AI-generated identification · may be incorrectOpaque, pale yellow-green, smooth and rounded with a waxy-looking luster. Hardness and crystal structure cannot be determined from the image; serpentine typically has Mohs hardness 2.5–5 and a monoclinic structure.

Physical properties
Opaque, pale yellow-green, smooth and rounded with a waxy-looking luster. Hardness and crystal structure cannot be determined from the image; serpentine typically has Mohs hardness 2.5–5 and a monoclinic structure.
Formation & geological history
If serpentine, it formed through hydration and alteration of ultramafic rocks, commonly during metamorphism; its age depends on the source deposit.
Uses & applications
Small tumbled stones are commonly used for collecting, decoration, and inexpensive jewelry.
Geological facts
The image does not show diagnostic features sufficient to confirm the mineral; several pale-green stones can look similar when polished.
Field identification & locations
A hardness test and examination of translucency, streak, and texture would help distinguish serpentine from alternatives such as calcite or jade. Serpentine occurs in ultramafic-rock belts worldwide.
