Physical properties
Hardness of 7 on the Mohs scale, typically gray or whitish in color, waxy to vitreous luster, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Formed through the mechanical weathering and water-transport erosion of larger quartz-bearing rocks, smoothed over long periods in riverbeds or marine environments
Uses & applications
Used in landscaping, decorative stone, and as a raw material in various industrial applications
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and is exceptionally resistant to weathering
Field identification & locations
Found worldwide in stream beds, beaches, and alluvial deposits; easily identified by its high hardness and lack of cleavage
