Physical properties
Hardness of 7 on Mohs scale, milky white to translucent color, vitreous luster, trigonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Formed via crystallization from silica-rich solutions or cooling magma, subsequently weathered and water-worn into a smooth pebble shape.
Uses & applications
Used in landscaping, decorative gravel, glassmaking, and abrasive products.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; commonly found in riverbeds and beaches worldwide.
