Tumbled rose quartz

Quartz, silicon dioxide (SiO₂), pink variety

AI-generated identification · may be incorrect

Mohs hardness 7; translucent pink with a glassy/vitreous luster and irregular internal fractures. It has a trigonal crystal structure, but tumbled pieces show no visible cleavage and exhibit conchoidal fracture; the color commonly comes from trace titanium, iron, or manganese.

Physical properties

Formation & geological history

Rose quartz crystallizes mainly in granitic pegmatites and hydrothermal veins as silica-rich fluids cool, typically during Precambrian to younger geological events. The specimen has been mechanically polished into a rounded cabochon-like shape.

Uses & applications

Used for ornamental carvings, beads, cabochons, décor, and inexpensive jewelry; it has no major industrial use beyond quartz-related silica applications.

Geological facts

Rose quartz is usually massive rather than well-crystallized; transparent, well-formed crystals are uncommon and often called pink quartz. Its color can fade with prolonged intense light or heat.

Field identification & locations

Common localities include Brazil, Madagascar, India, South Africa, and the United States. Identify it by its soft pink color, quartz-like hardness, glassy luster, and lack of cleavage; the image also includes a separate metallic-looking specimen above.
