Physical properties

Formation & geological history

Rose quartz forms mainly in hydrothermal veins and granitic pegmatites, with pink color associated with microscopic inclusions and trace elements. Most specimens are Precambrian to younger quartz-bearing material, then cut and polished for sale.

Uses & applications

Used as an ornamental stone, paperweight, cabochon, bead, and metaphysical collectible; quartz is also important industrially in glass, electronics, and abrasives.

Geological facts

The specimen appears to rest on a coarse granite or pegmatite matrix containing abundant white quartz, feldspar, and dark minerals. True rose quartz commonly has a cloudy, even pink tone rather than distinct crystals.

Field identification & locations

Identify by its pink color, glassy feel, lack of cleavage, and ability to scratch ordinary glass; a steel blade should not scratch it easily. Common sources include Brazil, Madagascar, India, and the United States.
