Likely quartz pebble

Quartz (SiO₂), possibly milky or iron-stained quartz

AI-generated identification · may be incorrect

Small, rounded, cream-white and slightly translucent, with a dull to glassy luster. Quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and specific gravity about 2.65; the image does not show enough detail to confirm identification.

Physical properties

Formation & geological history

Likely a fragment of quartz weathered from a quartz-rich rock and rounded during transport by water or other abrasion. Its geological age and original source cannot be determined from the photograph.

Uses & applications

Quartz is widely used in glassmaking, electronics, construction aggregates, and jewelry; this pebble is mainly suitable for collecting or decoration.

Geological facts

Quartz is one of Earth’s most abundant minerals and commonly survives weathering because it is relatively hard and chemically durable.

Field identification & locations

A hardness test (quartz scratches glass) and inspection for conchoidal fracture can help distinguish it from softer pale minerals. Quartz occurs worldwide in veins, igneous rocks, and sedimentary deposits.
