Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, and trigonal crystal system. It exhibits conchoidal fracture and lacks true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich solutions or cooling magma.
Uses & applications
Widely used in electronics, glassmaking, construction materials, and as a popular gemstone or decorative mineral specimen.
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 electronics.
Field identification & locations
Identified easily by its distinct hexagonal crystal habit when well-formed, high hardness that scratches glass, and lack of cleavage. Found globally in almost all geological settings.
