Physical properties
Hardness of 7 on the Mohs scale, white or translucent color, vitreous luster, conchoidal fracture, specific gravity of 2.65
Formation & geological history
Formed through the weathering and erosion of parent igneous or metamorphic rocks, transported by water and rounded into a pebble over long periods in sedimentary environments
Uses & applications
Used in landscaping, decorative stone, construction aggregate, and manufacturing of glass and silicon
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to both chemical and physical weathering
Field identification & locations
Found worldwide in riverbeds, beaches, and sedimentary deposits; easily identified by its high hardness and lack of cleavage
