Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and trigonal crystal system with colors ranging from clear to yellow-brown.
Formation & geological history
Forms abundantly in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich melts or hydrothermal solutions.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, abrasive materials, and gemstone jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified easily by its high hardness, lack of cleavage, and distinct conchoidal fracture; found globally in nearly all geological settings.
