Physical properties

Formation & geological history

Forms mainly in silica-rich pegmatites and hydrothermal veins, with pink color caused by microscopic inclusions or trace elements. It is generally Precambrian to younger, depending on its host deposit.

Uses & applications

Used as an inexpensive ornamental stone, cabochon, bead, carving material, and decorative aggregate; less commonly used industrially than clear quartz. Typical tumbled pieces have modest collector value.

Geological facts

Rose quartz is commonly cloudy and massive, unlike rare transparent pink quartz crystals. Color may fade with prolonged intense light or heat.

Field identification & locations

Common in Brazil, Madagascar, South Africa, India, and the United States. Identify by its pink color, glassy luster, hardness, and inability to scratch it with a steel knife; definitive identification may require testing because pink calcite or dyed stone can look similar.
