Physical properties
Hardness: 7 on Mohs scale; Color: Pale pink to lavender-pink; Luster: Vitreous to waxy; Crystal structure: Hexagonal (Trigonal); Cleavage: Indistinct; Specific gravity: 2.65
Formation & geological history
Forms primarily in pegmatites through the cooling of silica-rich hydrothermal fluids or magma. Its pink color is typically caused by fibrous inclusions of a pinkish mineral related to dumortierite.
Uses & applications
Extensively used in lapidary work for cabochons, carvings, and beads. Also popular as a decorative stone, in crystal healing, and as garden gravel.
Geological facts
Unlike other varieties of quartz, rose quartz rarely forms well-defined crystal faces and is almost always found in massive form. The largest deposits are found in Brazil, South Africa, and Madagascar.
Field identification & locations
Identify by its characteristic pink hue, high hardness (can scratch glass), and conchoidal fracture patterns. Commonly found in riverbeds or near granite pegmatites.
