Rose Quartz

Physical Properties

Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal structure: Hexagonal (Trigonal); Cleavage: Indistinct/Conchoidal fracture; Specific gravity: 2.65

Formation & Geological History

Formed primarily in pegmatites, which are igneous rock formations resulting from the slow cooling of magma. The pink color is caused by microscopic inclusions of dumortierite or similar minerals.

Uses & Applications

Commonly used in jewelry, ornamental carvings, cabochons, and as holistic 'healing crystals'. In industry, pure quartz is used for glassmaking and electronics, though rose quartz is mostly decorative.

Geological Facts

Unlike other varieties of quartz, rose quartz rarely forms large, well-defined crystal faces; it typically occurs in massive crystalline form. Many specimens exhibit 'asterism' or a star effect when cut as cabochons.

Field Identification & Locations

Identify by its translucent pink color and ability to scratch glass. It is commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota). Localities with large pegmatite veins are ideal for collecting.
