Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, conchoidal fracture, and no cleavage.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, often rounded by water transport in rivers or beaches over long periods.
Uses & applications
Used in glass manufacturing, electronics, abrasives, decorative landscaping, and as a tumbling stone for jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electrical charge under mechanical stress.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; commonly found worldwide in gravel beds, riverbanks, and beaches.
