Physical properties
Hardness of 7 on Mohs scale, typically white or translucent yellow-brown, vitreous luster, hexagonal crystal system.
Formation & geological history
Formed via crystallization from silicate melts or hydrothermal solutions, often weathered and water-worn into rounded pebbles over millions of years.
Uses & applications
Used in glassmaking, electronics, abrasive materials, and lapidary arts.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to chemical and physical weathering.
Field identification & locations
Easily identified by its conchoidal fracture and high hardness that scratches glass; found globally in rivers, beaches, and sedimentary deposits.
