Physical properties

Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: Indistinct/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Forms in pegmatites through the slow cooling of silica-rich magma. The pink color is caused by trace amounts of titanium, iron, or manganese.

Uses & applications

Mainly used for ornamental carvings, gemstones in jewelry, lapidary art, and as a popular metaphysical or decorative stone for collectors.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms well-defined crystal faces and is typically found in massive chunks. Large deposits were first found in the United States, but it has been used since ancient Roman and Egyptian times.

Field identification & locations

Identify by its translucent pink color and lack of well-formed crystal faces. It is common in Brazil, Madagascar, and South Dakota. It will easily scratch glass but cannot be scratched by a steel nail.
