Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Usually found in the cores of pegmatites (igneous) that formed at high temperatures and pressures deep in the Earth's crust. It forms as magma cools slowly, allowing large crystals to grow.

Uses & applications

Commonly used in jewelry, ornamental carvings, interior decoration, and as a popular semi-precious stone for gemstone collectors and metaphysical practitioners.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystal faces; it is almost always found in massive form. The pink color is often attributed to microscopic inclusions of a pink variety of the mineral dumortierite.

Field identification & locations

Identify by its characteristic pink hue, hardness (it will scratch glass), and lack of cleavage. Common locations include Brazil, Madagascar, South Africa, and the United States (South Dakota).
