Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, trigonal crystal system, conchoidal fracture with no cleavage, specific gravity of 2.65.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, often shaped and smoothed over long periods by water erosion in rivers or coastal environments.
Uses & applications
Widely used in landscaping, tumbling for decorative jewelry, glassmaking, and electronic components.
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 globally in riverbeds, beaches, and soil; identified easily by its high hardness which scratches glass and lack of cleavage.
