Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich magma or precipitation from hydrothermal fluids.
Uses & applications
Used extensively in glassmaking, electronics, oscillator crystals, abrasives, and as a semi-precious gemstone in jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in almost all rock types.
