Physical properties
Mohs hardness 7; pale pink, translucent to semi-translucent, with a vitreous to waxy luster and conchoidal fracture. Quartz is trigonal, though massive rose quartz typically lacks visible crystal faces; cleavage is absent or very poor, and specific gravity is about 2.65.
Formation & geological history
Forms mainly in granitic pegmatites and hydrothermal veins, commonly colored by microscopic inclusions of dumortierite or related minerals. The specimen is rounded and polished by human tumbling; quartz formed during Precambrian to Phanerozoic geological events.
Uses & applications
Used for beads, cabochons, carvings, meditation stones, and ornamental objects; it has limited industrial value compared with clear quartz. This appears to be a common polished fragment rather than gem-grade material.
Geological facts
Rose quartz is usually massive rather than well crystallized, unlike amethyst or rock crystal. Its pink color may fade with prolonged sunlight or heat.
Field identification & locations
Identify it by its consistent pale pink color, translucency, glassy appearance, hardness, and lack of cleavage; it should scratch glass but not be scratched by a steel knife. Common sources include Brazil, Madagascar, South Africa, India, and the United States.
