Rose quartz crystal cluster

Quartz, silicon dioxide (SiO₂), likely pink quartz; crystalline variety may be rose quartz

AI-generated identification · may be incorrect

Mohs hardness 7; pale pink to lilac, transparent to translucent, vitreous luster, typically hexagonal/trigonal quartz crystals with conchoidal fracture and no cleavage. Color commonly comes from trace inclusions of dumortierite, iron, or irradiation effects.

Physical properties

Formation & geological history

Forms when silica-rich hydrothermal fluids crystallize in cavities and fractures, commonly in granitic pegmatites; specimens may range from Precambrian to younger geological ages. The pictured piece appears partly crystalline and may include associated quartz matrix.

Uses & applications

Used as a collector specimen and, when attractive and translucent, in cabochons, beads, carvings, and ornamental objects; ordinary rose quartz has modest jewelry value.

Geological facts

Rose quartz is usually massive rather than sharply crystallized; distinct crystals are less common and may instead be pale amethyst or included quartz. It is not the same as pink glass or dyed quartz.

Field identification & locations

Identify by glassy luster, hardness sufficient to scratch ordinary glass, lack of cleavage, and quartz-like fracture; common localities include Brazil, Madagascar, India, and the United States. Avoid relying on color alone.
