Small rounded pale stone
Indeterminate; likely quartz-rich pebble, possibly quartz or light-colored feldspar
AI-generated identification · may be incorrectCream-white, smooth and rounded, with a dull to slightly waxy luster; hardness likely about 6–7 Mohs if quartz-rich. Grain size and crystal structure are not resolvable from the image, and cleavage cannot be assessed.

Physical properties
Cream-white, smooth and rounded, with a dull to slightly waxy luster; hardness likely about 6–7 Mohs if quartz-rich. Grain size and crystal structure are not resolvable from the image, and cleavage cannot be assessed.
Formation & geological history
Probably a naturally weathered pebble derived from quartz vein material, quartzite, or feldspar-bearing rock; its geological age is indeterminate. It may have been transported by stream, glacial, or beach processes.
Uses & applications
Suitable mainly as a curiosity, craft stone, or small landscaping material; no significant jewelry or industrial value can be established from the image.
Geological facts
The smooth shape indicates abrasion during transport or tumbling. A steel-knife or glass-scratch test can help distinguish softer calcite or feldspar from harder quartz, but testing may damage it.
Field identification & locations
Commonly encountered in stream gravels, beaches, glacial deposits, and landscaping aggregate worldwide; inspect for glassy luster, translucence, cleavage, and reaction to dilute acid. Estimated value: under $1–$5 as an ordinary pebble; more only if unusual composition or provenance is confirmed.
