Likely weathered granite or quartz-rich gravel
Granite, typically quartz + feldspar + mica; exact identification is uncertain from the image
AI-generated identification · may be incorrectPale pinkish-white, fine-to-medium granular fragments with a dull to slightly sparkling luster; likely Mohs hardness about 6–7, with no obvious cleavage on the rounded surfaces. Pink tones suggest potassium feldspar, while pale grains may be quartz.

Physical properties
Pale pinkish-white, fine-to-medium granular fragments with a dull to slightly sparkling luster; likely Mohs hardness about 6–7, with no obvious cleavage on the rounded surfaces. Pink tones suggest potassium feldspar, while pale grains may be quartz.
Formation & geological history
Probably eroded and naturally rounded pieces of granitic bedrock, formed by slow cooling of silica-rich magma deep underground, generally during Precambrian–Phanerozoic continental crust formation. The fragments may have been transported by stream, glacier, or landscaping fill.
Uses & applications
Common granite gravel is used for aggregate, paths, landscaping, concrete, and road construction; these small pieces have little jewelry value.
Geological facts
The rounded shapes and granular texture indicate abrasion and weathering rather than crystal growth. A fresh broken surface would show visibly interlocking quartz and feldspar grains.
Field identification & locations
Look for pink feldspar, translucent gray quartz, and occasional dark mica; granite is harder than glass and does not fizz with dilute acid. Common worldwide, especially in granitic terrains and river gravels.
