Formation & geological history

Forms from the crystallization of magma or from hydrothermal veins. Often found in pegmatites or metamorphic rocks. Can be found in geological formations across all ages, highly resistant to weathering.

Uses & applications

Used widely in glassmaking, electronics (piezoelectric properties), abrasives, and as decorative gemstones or carvings in jewelry and spiritual collections.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. The pink color in Rose Quartz is typically caused by trace amounts of titanium, iron, or manganese, or microscopic inclusions of dumortierite filaments.

Field identification & locations

Identify in the field by its hardness (it can scratch glass and steel knives) and its lack of cleavage, resulting in shell-like (conchoidal) fractures. Found worldwide, notably in Brazil, Madagascar, and the United States (South Dakota).
