Physical properties
Hardness of 7 on Mohs scale, transparent to opaque color, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of magma or precipitation from silica-rich hydrothermal solutions.
Uses & applications
Used extensively in electronics, glassmaking, precision instruments, gemstones, and ornamental carvings.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Easily identified by its distinct hexagonal crystal habit, lack of cleavage, and ability to scratch glass. Found worldwide in nearly all geological settings.
