Physical properties
Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65
Formation & geological history
Forms primarily in igneous pegmatites through the slow cooling of silica-rich magma; can also occur in hydrothermal veins. Specimens can range from millions to over a billion years old.
Uses & applications
Extensively used in lapidary work for cabochons, beads, and carvings; ornamental decor; and highly valued in the metaphysical community as the stone of unconditional love.
Geological facts
Unlike most other varieties of quartz which form large well-defined crystals, rose quartz usually occurs in massive crystalline form without distinct crystal faces. The pink hue is often attributed to microscopic inclusions of a pink fibrous mineral similar to dumortierite.
Field identification & locations
Identify in the field by its distinct pink hue, lack of cleavage, and the way it scratches glass. It is commonly found in Brazil, South Africa, India, and Madagascar; in the US, significant deposits are in South Dakota.
