Physical properties

Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: Indistinct/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Primary formation occurs in igneous environments, specifically pegmatites, where it crystallizes from silica-rich hydrothermal fluids. It can also be found in hydrothermal veins and metamorphic rocks. Most specimens date from the Precambrian to Cenozoic eras.

Uses & applications

Used extensively in jewelry as cabochons, carvings, and beads. In industry, high-purity quartz is used in glassmaking. It is also a popular specimen for metaphysical collectors and lapidary art.

Geological facts

Rose quartz is unique among quartz varieties because it rarely forms distinct crystal faces; it typically occurs as massive aggregates. It is often referred to as the 'Heart Stone' in folklore. The pink color is believed to be caused by submicroscopic inclusions of fibrous dumortierite silicate.

Field identification & locations

Identify in the field by its distinct conchoidal (shell-like) fracture, greasy luster, and inability to be scratched by a steel knife. Commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota). To collect, look for pink stains in white quartz veins.
