Physical properties

Formation & geological history

Quartz crystallizes from silica-rich hydrothermal fluids and igneous melts; rose coloration commonly comes from microscopic inclusions or trace elements. Its precise geological age and locality cannot be determined from the image.

Uses & applications

Used as a decorative and lapidary stone, in carvings, cabochons, and inexpensive jewelry; quartz is also important industrially in glass, electronics, and abrasives.

Geological facts

Rose quartz is commonly massive rather than forming sharply defined crystals. Color may fade with prolonged strong sunlight, and reddish-brown surface staining may reflect iron oxides.

Field identification & locations

Common sources include Brazil, Madagascar, South Africa, and the United States. Identify it by its pink color, hardness, glassy fracture, and inability to scratch it with a steel knife; testing is needed to distinguish it from dyed glass or other pink minerals.
