Physical properties

Hardness: 7 Mohs scale. Color: Pale pink to rose red. Luster: Vitreous (glassy). Crystal Structure: Hexagonal (trigonal), though usually occurs in massive form without visible crystal faces. Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.

Formation & geological history

Formed in igneous pegmatites through the slow cooling of magma rich in silica. It can also form in hydrothermal veins. The color is attributed to microscopic inclusions of pink borosilicate fibers (dumortierite-related minerals).

Uses & applications

Extensively used in lapidary work for cabochons, carvings, and beads. Popular in the metaphysical community and used in jewelry, interior decoration, and as a collectible specimen.

Geological facts

Unlike regular quartz, rose quartz rarely forms well-defined crystals; it is almost always found in large, blocky masses. It is often cloudy or translucent rather than transparent. Exposure to light can cause some specimens to fade over time.

Field identification & locations

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