Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with its pink color commonly caused by microscopic inclusions or trace elements. The specimen’s exact geological age and locality cannot be determined from the image.

Uses & applications

Used as a lapidary and ornamental stone, in carvings, cabochons, beads, and mineral collections; quartz also has major industrial uses in glass, ceramics, electronics, and abrasives.

Geological facts

The color of rose quartz is often relatively stable but may fade with prolonged heat or intense light. It is commonly confused with pink glass, calcite, or feldspar.

Field identification & locations

Check for glassy luster, conchoidal fracture, hardness, and lack of cleavage; quartz should scratch ordinary glass, though this test can damage the specimen. Common sources include Brazil, Madagascar, India, and South Africa.
