Physical properties

Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Typically colorless or white, but impurities create various colors.

Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through cooling magma, precipitation from hydrothermal solutions, or crystallization in sedimentary basins.

Uses & applications

Widely used in electronics, glassmaking, construction materials, and gemstone jewelry.

Geological facts

Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.

Field identification & locations

Identified by its high hardness (scratches glass), lack of cleavage, and distinct conchoidal fracture. Found globally in almost all geological settings.
