Physical properties

Hardness of 7 on Mohs scale, typically white or colorless, vitreous luster, hexagonal crystal system, and conchoidal fracture.

Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich magma or precipitation from hydrothermal solutions.

Uses & applications

Used extensively in electronics, glassmaking, construction materials, and as a semi-precious gemstone in jewelry.

Geological facts

Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it generates an electrical charge under mechanical stress.

Field identification & locations

Identified easily by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture; found worldwide in almost all geological settings.
