Physical properties
Hardness of 7 on the Mohs scale, milky white color, vitreous luster, trigonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Formed through mechanical weathering and aqueous transport of primary quartz veins or igneous rocks, smoothing over millions of years.
Uses & applications
Used in wire-wrapped jewelry, landscaping, decorative pathways, and abrasive manufacturing.
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 alluvial deposits; identified by its high hardness and lack of cleavage.
