Tumbled pink quartz (likely rose quartz)

Quartz, silicon dioxide (SiO₂), commonly microcrystalline or massive rose quartz

AI-generated identification · may be incorrect

Mohs hardness 7; pale pink to peach, translucent, with vitreous-to-waxy luster and no visible cleavage. Quartz is trigonal and has specific gravity about 2.65; the rounded shape and surface scratches indicate tumbling.

Physical properties

Formation & geological history

Forms mainly in silica-rich pegmatites and hydrothermal veins, with pink color usually caused by microscopic inclusions of dumortierite or related minerals. Its exact geological age cannot be determined from the photograph; deposits range from Precambrian to younger rocks.

Uses & applications

Used as an inexpensive ornamental stone, beads, cabochons, carvings, and metaphysical specimens; it is not generally used as a major construction aggregate in this form.

Geological facts

Rose quartz commonly has hazy translucence rather than strong crystal faces. The specimen could also be pale pink chalcedony or pink calcite, but its appearance most strongly suggests tumbled quartz.

Field identification & locations

Identify by hardness: it should scratch ordinary glass, while a steel blade usually will not scratch it; calcite would fizz weakly in acid and be much softer. Common sources include Brazil, Madagascar, South Africa, and India.
