Physical properties

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

Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich hydrothermal solutions and magmas.

Uses & applications

Widely used in electronics, glassmaking, oscillators, gemstones, and abrasive products.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.

Field identification & locations

Easily identified by its hardness, lack of cleavage, and characteristic conchoidal fracture. Found globally in almost all geological environments.
