Physical properties

Hardness of 7 on the Mohs scale, milky white color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.

Formation & geological history

Formed through the cooling and crystallization of silica-rich hydrothermal fluids in veins and igneous pegmatites.

Uses & applications

Widely used in glassmaking, electronics, ornamental carvings, and low-cost jewelry.

Geological facts

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

Field identification & locations

Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in nearly all geological environments.
