Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, and lacking cleavage with conchoidal fracture.
Formation & geological history
Formed through the mechanical weathering and water transport of larger quartz rocks or veins over long periods.
Uses & applications
Used in landscaping, decorative gravel, tumbling, and as a raw material for glassmaking and silica extraction.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to chemical weathering.
Field identification & locations
Found globally in riverbeds, beaches, and sedimentary deposits; easily identified by its high hardness and lack of cleavage.
