Rounded quartz-rich pebble, possibly milky quartz or quartzite

Quartz (SiO₂), or quartzite if the grainy texture is confirmed

AI-generated identification · may be incorrect

Pale cream-white, translucent in places, with a dull to slightly vitreous luster and rounded, water-worn shape; quartz hardness is Mohs 7, while quartzite is similarly hard and lacks obvious cleavage.

Physical properties

Formation & geological history

Likely formed as a quartz vein fragment or quartz-rich metamorphic rock, then transported and rounded by water or erosion. Its precise geological age and source cannot be determined from the image.

Uses & applications

Common quartz pebbles are used decoratively, in landscaping, and occasionally in lapidary work; quality material may be polished for ornamental objects.

Geological facts

The reddish-brown edge may be iron-oxide staining, while the uneven surface could reflect weathering or minor inclusions.

Field identification & locations

Quartz is identified by its hardness, lack of cleavage, and glassy fracture: it should scratch ordinary glass but not be scratched by a steel knife. Common sources include river gravels, beaches, quartz veins, and quartzite terrains.
