Physical properties
Small, rounded, opaque pale gray-green and brown specimen with a dull to slightly waxy surface and irregular light veins. Hardness and crystal structure cannot be determined visually; quartz-rich material is typically Mohs 7.
Formation & geological history
Likely a naturally weathered fragment transported and rounded by water; its source rock and geological age cannot be established from the image.
Uses & applications
No clear commercial use at this size; suitable as a common pocket or educational specimen.
Geological facts
The pale branching areas may be mineral veins, but the image does not show enough detail to identify their composition.
Field identification & locations
A rounded pebble with mottled coloring and possible veins; a fresh surface, hardness test, and closer inspection would help distinguish quartzite from other rocks. Pebbles of this kind occur in river and beach gravels worldwide.
