Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, hexagonal crystal system, conchoidal fracture.
Formation & geological history
Formed via crystallization from silica-rich solutions or cooling magma, subsequently weathered and water-worn in sedimentary environments.
Uses & applications
Used in landscaping, decorative aggregates, abrasives, and sometimes tumbled for jewelry.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, surviving weathering processes that destroy other minerals.
Field identification & locations
Found easily in riverbeds, beaches, and glacial outwash. Identified by its high hardness (scratches glass) and lack of cleavage.
