Physical properties
Hardness of 7 on the Mohs scale, typically white, clear, or grey in color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed through various geological processes including crystallization from magmatic melts, hydrothermal veins, and sedimentary deposition of resistant grains over millions of years.
Uses & applications
Used in landscaping, decorative items, manufacturing of glass and electronics, and lapidary work.
Geological facts
Quartz is one of the most abundant and durable minerals in the Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Found worldwide in beaches, riverbeds, and soils. Identified easily by its high hardness (scratches glass) and conchoidal fracture.
