Physical properties
Hardness of 7 on the Mohs scale, typically translucent to opaque, vitreous luster, and conchoidal fracture without cleavage.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, then weathered and water-worn into smooth pebbles.
Uses & applications
Used in landscaping, decorative aggregates, glassmaking, and polished as a low-cost gemstone.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, highly resistant to chemical weathering.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and smooth water-worn shape found in riverbeds and beaches.
