Physical properties

Hardness: 7 (Mohs scale); Color: Pale pink to rose red; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (usually massive); Cleavage: Indistinct; Specific Gravity: 2.65

Formation & geological history

Forms in late-stage crystallization of granitic pegmatites. It is often found in massive form rather than individual crystals. Most specimens are found in precambrian rocks dating back over 500 million years.

Uses & applications

Used primarily in lapidary work for cabochons, beads, and carvings. Also used as a gemstone in jewelry, decorative ornaments, and widely collected by mineral enthusiasts for its color.

Geological facts

The pink color is traditionally attributed to trace amounts of titanium, iron, or manganese, although more recent research suggests microscopic inclusions of pink borosilicate fibers (related to dumortierite) create the color.

Field identification & locations

Identify by its characteristic pink hue and lack of flat crystal faces (it usually occurs as a massive lump). Common locations include Brazil, Madagascar, South Dakota (USA), and India. Collectors look for clarity and deep color saturation.
