Physical properties

Formation & geological history

If quartz, it crystallized from silica-rich fluids or magma and was later weathered and rounded during transport; its geological age and source cannot be determined from the photograph.

Uses & applications

Quartz is used in glassmaking, electronics, abrasives, and jewelry; this small rough piece is primarily a casual or educational collectible.

Geological facts

Quartz is one of Earth’s most abundant minerals and commonly survives erosion because it is relatively hard and chemically resistant.

Field identification & locations

Its pale color and pebble shape are consistent with quartz, but confirmation requires checking hardness and fracture; similar pale stones include feldspar and limestone. Quartz occurs worldwide in veins, igneous rocks, and sedimentary gravel.
