Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, conchoidal fracture, and hexagonal crystal system.
Formation & geological history
Formed through the cooling of magma or crystallization from hydrothermal veins, often weathered and rounded by water transport in sedimentary environments.
Uses & applications
Used in glassmaking, electronics, abrasives, gemstones, and as decorative landscape gravel.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and resistance to chemical weathering, commonly found in riverbeds and beaches worldwide.
