White pebbles (rock material not identifiable from the image)
Undetermined; the smooth, pale pieces could be quartz, quartzite, or another light-colored rock
AI-generated identification · may be incorrectSmall, rounded to irregular white pieces with a dull-to-slightly glossy surface. Hardness, mineral composition, and crystal structure cannot be established from appearance alone.

Physical properties
Small, rounded to irregular white pieces with a dull-to-slightly glossy surface. Hardness, mineral composition, and crystal structure cannot be established from appearance alone.
Formation & geological history
Likely naturally rounded fragments, though the image does not show enough detail to determine their material, formation process, or age.
Uses & applications
Pebbles of this general appearance are used in landscaping, decoration, and craft projects; the pictured pieces have no clear gem value.
Geological facts
The bright colored background and limited detail make reliable identification impossible; similar-looking white pebbles can be made of several different minerals or rocks.
Field identification & locations
A close-up view and tests such as hardness, streak, and acid reaction would help distinguish quartz or quartzite from calcite and other possibilities. Common white pebbles occur in river and beach gravels.
