Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms through crystallization from silica-rich hydrothermal solutions, magma, or through metamorphic and sedimentary processes across various geological eras.
Uses & applications
Used widely in glassmaking, electronics, oscillators, abrasives, and as a popular gemstone or lapidary specimen in jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties, generating electricity under mechanical stress.
Field identification & locations
Easily identified by its distinct hardness that scratches glass, lack of cleavage, and six-sided crystal habit when well-formed. It is globally ubiquitous.
