Physical properties
Hardness of 7 on the Mohs scale, clear to white color, vitreous luster, hexagonal crystal system, and no cleavage with conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich fluids at various temperatures.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, and as a popular gemstone or ornamental carving material.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating electricity under mechanical stress.
Field identification & locations
Easily identified by its distinct crystal habit, high hardness that scratches glass, and lack of cleavage; found globally in nearly all geological settings.
