Tumbled rose quartz

Quartz, silicon dioxide (SiO₂), pink variety

AI-generated identification · may be incorrect

Mohs hardness 7; pale pink, translucent to opaque, with a vitreous luster and conchoidal fracture rather than cleavage. The rounded shape indicates mechanical tumbling and polishing; microscopic inclusions commonly cause the pink color.

Physical properties

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal quartz veins, with coloration generally attributed to microscopic mineral inclusions or structural defects. The specimen’s exact geological age and locality cannot be determined from the image.

Uses & applications

Used for inexpensive cabochons, beads, carvings, ornamental objects, meditation stones, and collector specimens; it has limited industrial value compared with clear quartz.

Geological facts

Rose quartz is widespread and usually cloudy rather than strongly transparent. Natural crystals are uncommon; most commercial material is sold as rough pieces, polished stones, or carvings.

Field identification & locations

Identify by its consistent pink color, glassy luster, hardness sufficient to scratch ordinary glass, and absence of obvious cleavage; do not confuse it with pink calcite, which is softer and cleaves readily. Common sources include Brazil, Madagascar, India, and South Dakota, USA.
