Physical properties
Hardness: 7 (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
Formed in late-stage crystallization of pegmatites (igneous) through high temperature and pressure. The pink color is attributed to microscopic inclusions of a pink fibrous silicate mineral related to dumortierite.
Uses & applications
Used primarily in jewelry, ornamental carvings, tumbling/polishing for collectors, and in the lapidary arts. Also popular in metaphysical practices.
Geological facts
Rose quartz is unique among quartz varieties because it is rarely found as well-formed crystals; it usually occurs as massive, cloudy chunks. The first known source was discovered in Brazil.
Field identification & locations
Identify by its characteristic pink hue, hardness (will scratch glass), and lack of cleavage. Commonly found in Brazil, South Africa, India, and Madagascar. In its tumbled form seen here, look for internal veining or clouds.
