Uses & applications

Used for ornamental carvings, beads, cabochons, decorative stones, and inexpensive jewelry; polished specimens are popular with collectors. It has limited industrial value compared with clear quartz.

Geological facts

Rose quartz commonly shows internal fractures and cloudy color, and some specimens exhibit asterism when cut as cabochons. The pink color can fade with prolonged sunlight or heating.

Field identification & locations
