Physical properties

Formation & geological history

Rose quartz forms mainly in granite-related pegmatites and hydrothermal veins, where trace elements and microscopic inclusions produce its pink color. Most specimens are Precambrian to younger, depending on the host granite.

Uses & applications

Used as an ornamental stone, carving material, tumbled stone, and inexpensive jewelry or décor; this small polished piece has modest commercial value.

Geological facts

The pink color is often linked to microscopic inclusions of dumortierite-like minerals or irradiation-related defects rather than a single universal coloring agent.

Field identification & locations

Identify it by its soft pink color, glassy luster, conchoidal fracture, and inability to scratch with a steel knife; quartz can scratch glass. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
