Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the crystallization of silica-rich solutions or cooling magma, subsequently weathered and water-smoothed into a pebble over millions of years.
Uses & applications
Used in glassmaking, electronics, abrasives, gemstones, and landscaping decorative gravel.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in rivers, beaches, and sedimentary deposits.
