White beach pebble, likely quartzite

Quartzite (predominantly quartz, SiO₂); identification is uncertain from the image alone

AI-generated identification · may be incorrect

Small, smooth, rounded off-white pebble with a matte to slightly waxy surface. Quartzite is Mohs 7, with interlocking quartz crystals, no cleavage, and specific gravity around 2.6–2.7; those properties cannot be confirmed visually here.

Physical properties

Formation & geological history

Likely a quartz-rich rock hardened by metamorphism, then rounded by water or abrasion. Its geological age and exact source cannot be determined from the image.

Uses & applications

Pebbles like this are used for decoration, crafts, and collections; quartzite also has uses as aggregate and building stone.

Geological facts

Quartzite is resistant to scratching and weathering because its quartz grains are strongly fused.

Field identification & locations

The smooth, rounded shape suggests transport or tumbling; a hardness test and close inspection of a fresh surface could help distinguish quartzite from other pale pebbles. Quartzite occurs worldwide.
