Small rounded pebble, likely quartzite or quartz-rich stone

Unidentified quartz-rich lithic pebble; exact identification is not possible from the image

AI-generated identification · may be incorrect

Cream to pale tan, smooth and rounded, with a dull to faintly waxy luster and no visible crystals or cleavage. If quartz-rich, hardness is about 7 Mohs; grain size and specific gravity cannot be determined visually.

Physical properties

Cream to pale tan, smooth and rounded, with a dull to faintly waxy luster and no visible crystals or cleavage. If quartz-rich, hardness is about 7 Mohs; grain size and specific gravity cannot be determined visually.

Formation & geological history

Likely a naturally weathered pebble transported and rounded by water or sediment. Its source rock may be much older, but the image does not establish its composition or age.

Uses & applications

Common pebbles are used decoratively, in landscaping, or as inexpensive collectibles; no special commercial value is apparent.

Geological facts

The smooth shape suggests abrasion during transport, but many different rocks can weather to a similar appearance.

Field identification & locations

A fresh broken surface, hardness test, and streak or acid tests would help distinguish quartzite, quartz, and other pale stones. Rounded pebbles occur in riverbeds, beaches, and glacial deposits worldwide.
