White quartz pebbles

Quartz, SiO₂ (likely milky quartz)

AI-generated identification · may be incorrect

White to translucent, with a glassy-to-waxy luster and no visible cleavage; quartz has a hexagonal crystal structure, Mohs hardness 7, and specific gravity about 2.65. The smooth, rounded surfaces indicate water or mechanical tumbling.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich fluids in many geological settings and is highly resistant to weathering; these pebbles were likely rounded in streams or during commercial tumbling. Quartz is common across rocks of many ages.

Uses & applications

Used for landscaping, decoration, craft projects, and sometimes as feedstock for glass or silica products; these pieces appear suited to decorative use.

Geological facts

Quartz is one of Earth’s most abundant minerals and is the principal component of many sands and quartz-rich rocks.

Field identification & locations

Look for hardness sufficient to scratch glass, absence of cleavage, and a white streak; the image shows rounded white pebbles, but does not establish their exact composition. Quartz occurs worldwide; similar-looking pebbles may include other pale minerals.
