Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, transparent to translucent, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich fluids or magma.
Uses & applications
Used extensively in glassmaking, electronics, oscillators, abrasives, and as a gemstone or specimen in jewelry.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and six-sided crystal terminations when well-formed.
