Physical properties
Hardness of 7 on the Mohs scale, white to clear coloration, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through crystallization in hydrothermal veins or igneous pegmatites, subsequently weathered and water-worn into smooth pebbles.
Uses & applications
Used in glassmaking, electronics, abrasives, and as decorative landscape or tumbling stones.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and resistance to chemical weathering, commonly found in riverbeds and beaches worldwide.
