Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins when silica-rich fluids crystallize; many deposits are Precambrian to younger. The specimen’s exact locality and age cannot be determined from the image.

Uses & applications

Used as an inexpensive ornamental stone, beads, carvings, cabochons, and meditation or gift items; it has limited industrial value compared with ordinary quartz.

Geological facts

Pink color is often linked to microscopic inclusions of dumortierite-like materials or other mineral defects, rather than manganese alone. Strongly transparent pink quartz is uncommon.

Field identification & locations

Identify by its uniform pink color, glassy surface, hardness, and lack of cleavage; it should scratch glass but not be scratched by a steel knife. Common sources include Brazil, Madagascar, India, and South Africa.
