Physical properties

Hardness of 7 on the Mohs scale, pale pink to white coloration, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, and a specific gravity of 2.65.

Formation & geological history

Formed through the crystallization of silica-rich hydrothermal solutions or magmatic pegmatites, later weathered and water-worn into a smooth pebble over millions of years.

Uses & applications

Used in lapidary arts, decorative landscaping, tumbling, and crystal collecting.

Geological facts

Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it generates an electrical charge when compressed.

Field identification & locations

Can be identified in the field by its high hardness (scratches glass), conchoidal fracture, and resistance to chemical weathering. Found worldwide in riverbeds, beaches, and quartz veins.
