Physical properties
Hardness: 7 on Mohs scale; Color: Pink to rose-red; Luster: Vitreous to greasy; Crystal structure: Trigonal (often occurs in massive form); Cleavage: None/Conchoidal fracture; Specific gravity: 2.65
Formation & geological history
Formed in pegmatites through the cooling of silica-rich magma or in hydrothermal veins. The pink color is attributed to microscopic inclusions of pink borosilicate fibers (similar to dumortierite).
Uses & applications
Primarily used in jewelry, ornamental carvings, lapidary work, and for metaphysical collection purposes.
Geological facts
Unlike amethyst or citrine, rose quartz rarely forms well-defined crystal faces; it usually occurs in massive chunks. It is known as the 'Stone of Love' in many cultures.
Field identification & locations
Identify by its characteristic pink hue and conchoidal fracture (glass-like curves when broken). It cannot be scratched by a steel knife. Major sources include Brazil, Madagascar, and South Dakota, USA.
