Physical properties

Hardness 7 Mohs; pale pink to milky white with locally greenish staining, vitreous to waxy luster, massive granular structure, no cleavage, and conchoidal fracture. Specific gravity is about 2.65.

Formation & geological history

Forms mainly in coarse-grained granitic pegmatites and hydrothermal veins as quartz crystallizes from silica-rich fluids, generally during Precambrian to Phanerozoic igneous activity. This specimen has been cut and polished.

Uses & applications

Used for ornamental slabs, carvings, beads, cabochons, and inexpensive jewelry; also collected as a decorative quartz specimen.

Geological facts

Rose quartz is commonly massive rather than sharply crystallized; transparent pink quartz crystals are a rarer variety often termed pink quartz. Its color may fade with prolonged strong sunlight or heat.

Field identification & locations

Identify by its pink milky appearance, glassy polish, hardness sufficient to scratch ordinary glass, and lack of cleavage; acid does not visibly react. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
