Tumbled rose quartz
Quartz, silicon dioxide (SiO₂), pink variety
AI-generated identification · may be incorrectHardness 7 Mohs; pale pink to salmon, translucent, with a vitreous-to-waxy luster and no cleavage. It is microcrystalline quartz, so distinct crystal faces are usually absent; the surface appears polished or weathered rather than naturally crystalline.

Physical properties
Hardness 7 Mohs; pale pink to salmon, translucent, with a vitreous-to-waxy luster and no cleavage. It is microcrystalline quartz, so distinct crystal faces are usually absent; the surface appears polished or weathered rather than naturally crystalline.
Formation & geological history
Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with its color commonly attributed to microscopic inclusions of minerals such as dumortierite or related phases. The specimen appears human-shaped or tumbled; its exact geological age cannot be determined visually.
Uses & applications
Used as an ornamental stone, beads, carvings, cabochons, and inexpensive jewelry; attractive polished pieces are popular among collectors.
Geological facts
Rose quartz commonly shows weak translucency and may display asterism when cut as a cabochon. Its pink color can fade with prolonged strong sunlight or heat.
Field identification & locations
Identify by its pink translucent quartz appearance, glassy luster, hardness, and lack of cleavage; it should scratch glass but not be scratched by a steel knife. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
