Physical properties
Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Formed through the crystallization of magma (igneous) or from hydrothermal vents. It is most commonly found in massive forms within pegmatites rather than as distinct crystals.
Uses & applications
Extensively used in lapidary work for cabochons, beads, carvings, and decorative ornaments. Also popular in jewelry and as healing stones in metaphysical practices.
Geological facts
Unlike clear quartz, rose quartz rarely forms well-defined crystal faces; it usually occurs in translucent, massive chunks. Its pink color is historically attributed to titanium, though more recent research suggests microscopic needle-like inclusions of a pinkish fibrous mineral may be responsible.
Field identification & locations
Identify by its characteristic pink hue, high hardness (it will scratch glass), and lack of cleavage (it breaks into curved, glass-like shards). Commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
