Physical properties

Hardness of 7 on the Mohs scale, vitreous luster, colorless to white, conchoidal fracture with no true cleavage, and hexagonal crystal system.

Formation & geological history

Forms in a wide range of geological environments, most commonly crystallized from silica-rich hydrothermal veins and magma or deposited in sedimentary rocks.

Uses & applications

Widely used in electronics, oscillators, glassmaking, abrasives, and as a semi-precious gemstone in jewelry.

Geological facts

Quartz is one of the most abundant and ubiquitous minerals in Earth's continental crust, exhibiting piezoelectric properties.
