Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. It occurs in various colors including clear, white, purple, and pink.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich fluids at various temperatures and pressures.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, and as gemstones or decorative mineral specimens.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, making it useful in watches and electronic oscillators.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and distinct conchoidal fracture. Found worldwide in nearly every geological environment.
