Physical properties
Hardness of 7 on Mohs scale, white to clear color, vitreous luster, trigonal crystal system, conchoidal fracture.
Formation & geological history
Formed via crystallization from silica-rich solutions or magmas, often weathered and water-worn into smooth pebbles over millions of years.
Uses & applications
Used in glassmaking, abrasives, electronics, landscaping, and as lapidary material for decorative tumbling.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; commonly found in riverbeds, beaches, and sedimentary deposits worldwide.
