White quartz pebble

Quartz (silicon dioxide, SiO₂), likely milky quartz

AI-generated identification · may be incorrect

Opaque cream-white, dull to vitreous luster, rounded and weathered; quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage, but the image alone cannot confirm composition.

Physical properties

Opaque cream-white, dull to vitreous luster, rounded and weathered; quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage, but the image alone cannot confirm composition.

Formation & geological history

Likely a quartz-rich pebble rounded by transport in water or by weathering; quartz forms in many rock types over a wide range of geological ages.

Uses & applications

Commonly collected or used in landscaping and decorative crafts; suitable for tumbling if confirmed to be quartz.

Geological facts

Quartz is one of Earth’s most abundant minerals and resists chemical weathering, allowing it to persist as rounded pebbles.

Field identification & locations

Its pale color and rounded shape fit milky quartz, but a scratch test against glass (quartz should scratch it) can help distinguish it from softer pale stones. Quartz pebbles occur worldwide in riverbeds, beaches, and gravel deposits.
