Physical properties
Hardness of 7 on the Mohs scale, peach to light pink color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Forms in a wide variety of geological environments, commonly crystallizing from hydrothermal veins and cooling magma, often weathered and water-worn into smooth pebbles found in streams and beaches.
Uses & applications
Used in electronics, glassware, gemstone carving, decorative items, and as a popular specimen for mineral collectors.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust. Water-worn pebbles like this one are shaped by prolonged tumbling action in rivers or ocean surf.
Field identification & locations
Easily identified by its hardness (scratches glass) and lack of cleavage. Common worldwide in stream beds, beaches, and alluvial deposits.
