Physical properties

Hardness: 7 on Mohs scale. Color: Pale pink to rose red. Luster: Vitreous (glassy). Crystal Structure: Hexagonal (trigonal), though rarely found as distinct crystals. Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.

Formation & geological history

Forms in PEGMATITES (igneous rock) and hydrothermal veins. The pink color is usually attributed to trace amounts of titanium, iron, or manganese, or microscopic mineral inclusions of a pinkish fibrous silicate.

Uses & applications

Widely used as an ornamental stone, in jewelry (beads, cabochons), and for decorative carvings. It is also highly popular in the metaphysical and gemstone collecting communities.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystals. It is the state mineral of South Dakota. The name is derived from its unique rose-pink hue.

Field identification & locations

Identify by its translucent pink color and inability to be scratched by a steel blade. It is commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
