Physical properties

Hardness: 7 on the Mohs scale. Color: Soft pink to rose red. Luster: Vitreous to greasy. Crystal structure: Hexagonal/Trigonal (typically found as massive aggregates). Cleavage: None (conchoidal fracture). Specific gravity: 2.65.

Formation & geological history

Forms primarily in pegmatites, hydrothermal veins, and magmatic rocks through the slow cooling of silica-rich molten rock. Its pink color is typically attributed to trace amounts of titanium, iron, or manganese, or microscopic inclusions of fibrous dumortierite.

Uses & applications

Widely used as an ornamental stone, in gemstone jewelry (cabochons, beads, carvings), and as a popular healing crystal/collectible mineral specimen.

Geological facts

Unlike standard clear quartz crystals, rose quartz rarely forms well-defined individual crystal faces and usually occurs in large, translucent masses. Larger crystals are extremely rare and highly prized by collectors.

Field identification & locations

Identified by its distinctive pale pink color, vitreous to greasy luster, hardness of 7 (scratches glass), and conchoidal fracture. Major sources include Brazil, Madagascar, South Africa, and the United States (South Dakota).
