Physical properties

Hardness of 7 on the Mohs scale, typically white or pinkish in this form, vitreous luster, trigonal crystal system, and no true cleavage.

Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through cooling magmas or precipitation from silica-rich solutions.

Uses & applications

Used in jewelry, electronics, and construction materials due to its abundance and piezoelectric properties.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong resistance to both chemical and mechanical weathering.

Field identification & locations

Identify by its distinct conchoidal fracture and high scratch resistance against glass and steel. Found globally in almost all geological settings.
