Physical properties

Formation & geological history

Quartz formed in igneous or hydrothermal environments and later weathered into a rounded pebble; its exact geological age and source cannot be determined from the photograph.

Uses & applications

Used for decorative stones, landscaping, glass and ceramic manufacture, abrasives, and occasionally cabochons or carvings.

Geological facts

The cloudy appearance results from microscopic fluid inclusions, fractures, or other trapped impurities. Quartz is one of Earth’s most abundant and durable minerals.

Field identification & locations

Identify it by its glassy/waxy appearance, lack of cleavage, and ability to scratch ordinary glass; hardness testing should be done inconspicuously. Common worldwide in veins, granite-derived sediments, river gravels, beaches, and glacial deposits.
