Physical properties

Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65

Formation & geological history

Typically formed in hydrothermal veins or pegmatites at high temperatures. The pink hue is caused by trace amounts of titanium, iron, or manganese, or microscopic inclusions of aluminum-borosilicate or fibrous dumortierite.

Uses & applications

Commonly used in jewelry, as ornamental beads, carvings, decorative spheres, and in lapidary work. It is also popular in holistic and spiritual practices as a stone of love.

Geological facts

Unlike other quartz varieties, rose quartz rarely forms large, well-defined crystals and usually occurs in massive form. The color can fade if exposed to excessive sunlight.

Field identification & locations

Identifiable by its characteristic pink color and hardness (it will scratch glass). It has a greasy or waxy feel when polished. It is widely distributed, with major deposits in Brazil, Madagascar, and South Dakota, USA.
