Small weathered quartz-rich pebble
Likely quartz (SiO₂), possibly quartzite or feldspar-bearing rock
AI-generated identification · may be incorrectPale cream to gray, granular texture, dull to weakly vitreous luster, and no clearly visible cleavage; quartz hardness is Mohs 7, while feldspar is about 6. The specimen appears irregular and naturally weathered, but the image is insufficient for definitive identification.

Physical properties
Pale cream to gray, granular texture, dull to weakly vitreous luster, and no clearly visible cleavage; quartz hardness is Mohs 7, while feldspar is about 6. The specimen appears irregular and naturally weathered, but the image is insufficient for definitive identification.
Formation & geological history
Likely derived from erosion of a quartz-bearing igneous or metamorphic rock, then transported and rounded; its exact geological age and source cannot be determined visually.
Uses & applications
Common quartz pebbles have little commercial value individually, though quartz and quartzite are used in glass, ceramics, construction aggregate, countertops, and decorative stone.
Geological facts
The pale, sugary appearance may indicate quartzite or a feldspar-rich fragment rather than pure quartz. A hardness test, streak test, and magnified inspection would improve identification.
Field identification & locations
Look for glassy translucence and lack of cleavage for quartz; feldspar shows two cleavage directions and commonly breaks into blocky faces. Common worldwide in stream gravels, soils, and weathered bedrock.
