Physical properties
Hardness of 7 on the Mohs scale. Color ranges from colorless to white, grey, or various shades depending on impurities. Vitreous luster and trigonal crystal system with conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich melts and hydrothermal fluids.
Uses & applications
Widely used in electronics, glassmaking, abrasives, and as a gemstone or ornamental mineral.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
