Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, transparent to translucent with no cleavage, and trigonal crystal system.
Formation & geological history
Formed through crystallization in igneous and metamorphic environments, subsequently weathered and water-worn into a smooth pebble.
Uses & applications
Used in landscaping, decorative gravel, glassmaking, and abrasive grit.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, highly resistant to chemical and mechanical weathering.
Field identification & locations
Easily identified by its high hardness (scratches glass) and conchoidal fracture, commonly found in riverbeds and beaches worldwide.
