Physical properties

Hardness: 7 on 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

Forms in igneous pegmatites through the slow cooling of magma rich in silica, manganese, or titanium. Most specimens are from the Phanerozoic eon. It typically occurs as a massive core in large pegmatite bodies.

Uses & applications

Used primarily in lapidary work for cabochons, beads, and carved figurines. It is popular in the metaphysical community and as a decorative mineral specimen for collectors.

Geological facts

Unlike most quartz varieties that form distinct crystals, rose quartz is typically massive. Rose quartz druzy (small crystals on a matrix) like the one pictured is much rarer than massive chunks. The pink color is often attributed to microscopic inclusions of a fibrous pink mineral similar to dumortierite.

Field identification & locations

Identify in the field by its distinctive pink color, glass-like luster, and inability to be scratched by a steel knife. It is commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
