Physical properties

Hardness: 7 on Mohs scale; Color: pale pink to rose red; Luster: Vitreous; Crystal structure: Trigonal (Hexagonal system); Cleavage: No true cleavage, conchoidal fracture; Specific gravity: 2.65.

Formation & geological history

Formed in high-temperature silica-rich environments, usually found in the cores of pegmatites formed during the late stage of magma crystallization. Often millions of years old.

Uses & applications

Commonly used in jewelry, ornamental carving, and decorative gemstones. In industry, high-purity quartz is used for glassware and electronics, though rose quartz specifically is prized primarily for aesthetics.

Geological facts

The pink color is attributed to microscopic inclusions of fibrous dumortierite or trace amounts of titanium, iron, or manganese. Unlike most quartz, it rarely forms well-defined crystals.

Field identification & locations

Identify in the field by its distinct pink translucent color, glassy luster, and ability to scratch glass. Found in abundance in Brazil, South Africa, Madagascar, and the United States (South Dakota).
