Physical properties

Hardness: 7 on the Mohs scale; Color: pale pink to rose red; Luster: vitreous to greasy; Crystal Structure: Trigonal (often occurs in massive form rather than distinct crystals); Cleavage: none (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed at high temperatures in deep-seated pegmatites and hydrothermal veins. It crystallizes from magma and can be found in igneous rock formations millions of years old.

Uses & applications

Primarily used in jewelry (cabochons, beads), gemstone carvings, and as a popular specimen for crystal healing and mineral collecting.

Geological facts

Unlike most other varieties of quartz, rose quartz rarely forms large, well-defined crystals; it usually grows in large, shapeless masses. Its pink color is often attributed to microscopic inclusions of a pink fibrous mineral related to dumortierite.

Field identification & locations

Identify in the field by its distinct translucent pink hue and lack of cleavage planes. Found globally with major deposits in Brazil, Madagascar, South Africa, and the United States (South Dakota and New England).
