Physical properties

Formation & geological history

Could be quartz weathered from a vein or quartzite carried and rounded by water. Its age and precise source cannot be determined visually.

Uses & applications

Primarily a decorative or collecting pebble; quartz and quartzite also have industrial and construction uses.

Geological facts

Water abrasion can smooth and round resistant quartz-rich stones over long periods.

Field identification & locations

Look for hardness, glassy luster, and lack of cleavage; quartz scratches glass, though a pebble may contain other minerals. Common sources include river and beach gravels.
