Physical properties

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal veins, where trace elements and microscopic inclusions create the pink color; most specimens are Precambrian to Phanerozoic in age. This piece has been rounded and polished by tumbling.

Uses & applications

Used for beads, carvings, cabochons, ornamental objects, and inexpensive collection specimens; rarely used as an industrial quartz source.

Geological facts

The color may result from nanoscale dumortierite-like inclusions or other trace materials, rather than simply manganese. Strongly colored transparent material is uncommon and more valuable than ordinary massive rose quartz.

Field identification & locations

Identify it by its pink color, glassy polish, lack of cleavage, and ability to scratch glass; confirm with hardness and specific-gravity tests. Important sources include Brazil, Madagascar, India, South Africa, and the United States.
