Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy) to greasy; Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Forms primarily in pegmatites (igneous) through hydrothermal crystallization. The color is attributed to microscopic inclusions of pink borosilicate fibers. Usually found in massive form rather than distinct crystals.

Uses & applications

Extensively used in jewelry (cabochons, beads), decorative carvings, and as a popular semi-precious gemstone for collectors and metaphysical enthusiasts.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystals. It is the state mineral of South Dakota and has been used in ornaments since at least 700 BC in ancient Mesopotamia.

Field identification & locations

Identify by its translucent pink color and inability to be scratched by a steel knife. It is commonly found in Brazil, Madagascar, and various US states like Maine and South Dakota. Collectors look for deep color saturation and 'asterism' (a star effect when cut).
