White pebble, likely milky quartz
Probably quartz (SiO₂); identification is uncertain from the image alone.
AI-generated identification · may be incorrectSmall, opaque white, smoothly rounded pebble with a dull-to-waxy surface. If quartz, hardness is 7 Mohs, with a trigonal crystal structure and no cleavage; the visible color and shape are not diagnostic.

Physical properties
Small, opaque white, smoothly rounded pebble with a dull-to-waxy surface. If quartz, hardness is 7 Mohs, with a trigonal crystal structure and no cleavage; the visible color and shape are not diagnostic.
Formation & geological history
Could be a water-worn fragment from quartz-rich rock, later rounded by transport; its geological age and exact source cannot be determined visually.
Uses & applications
Small quartz pebbles are used for crafts, decoration, and teaching collections; this piece appears to have little commercial value.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly occurs in veins and many rock types.
Field identification & locations
A hardness test showing it scratches glass would support quartz identification; the image does not establish composition, and white calcite or other minerals can look similar. Common quartz-bearing rocks occur worldwide.
