Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Typically colorless or white, but impurities can produce various shades.
Formation & geological history
Forms in a wide range of geological environments, prominently in igneous, metamorphic, and sedimentary rocks. Often crystallizes from silica-rich hydrothermal veins and magma.
Uses & applications
Widely used in electronics, glassmaking, oscillators, abrasive materials, and as a semi-precious gemstone in jewelry.
Geological facts
Quartz is one of the most abundant and ubiquitous minerals found in the Earth's continental crust. Its piezoelectric properties make it essential for timing devices in watches.
Field identification & locations
Identified easily by its distinct conchoidal fracture, high hardness scratching glass, and lack of cleavage. Found worldwide in nearly every geological setting.
