Tumbled pink quartz (likely rose quartz)

Rose quartz, quartz (SiO₂)

AI-generated identification · may be incorrect

Pale pink, translucent-to-opaque, with a smooth tumbled surface and vitreous-to-waxy luster; hardness 7 Mohs, hexagonal crystal structure, no prominent cleavage, and specific gravity about 2.65. The rounded shape indicates human tumbling.

Physical properties

Pale pink, translucent-to-opaque, with a smooth tumbled surface and vitreous-to-waxy luster; hardness 7 Mohs, hexagonal crystal structure, no prominent cleavage, and specific gravity about 2.65. The rounded shape indicates human tumbling.

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal veins, commonly as massive quartz rather than visible crystals. Its pink color is associated with trace elements and microscopic inclusions; ages vary by deposit, often Precambrian to younger.

Uses & applications

Used as an ornamental stone, beads, carvings, décor, and inexpensive jewelry; industrial quartz is used for glass, ceramics, and electronics, though attractive rose quartz is primarily decorative.

Geological facts

Rose quartz commonly displays a soft pink color and may show star-like asterism when cut as a cabochon. The pictured specimen could also be pink chalcedony or dyed quartz, which cannot be confirmed visually.

Field identification & locations

Identify by its glassy hardness, lack of cleavage, pale pink color, and resistance to scratching by steel; it should scratch glass. Common sources include Brazil, Madagascar, India, and South Africa.
