Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed in late-stage crystallization of pegmatites (igneous) through cooling of magma under high pressure. It can also be found in hydrothermal veins.

Uses & applications

Used primarily in lapidary work for cabochons, beads, and carvings. Also popular in jewelry, as an ornamental stone, and in metaphysical collecting.

Geological facts

The pink color is traditionally attributed to trace amounts of titanium, iron, or manganese, though recent research suggests microscopic needle-like inclusions of a fibrous silicate mineral cause the color.

Field identification & locations

Identify by its characteristic pink hue, high hardness (will scratch glass), and lack of cleavage. Commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
