Physical properties
Hardness: 7-7.5 (Tourmaline), 7 (Quartz); Color: Pink to rubellite red embedded in white or translucent matrix; Luster: Vitreous to greasy; Crystal structure: Trigonal/Hexagonal; Cleavage: Indistinct; Specific gravity: 3.0-3.2
Formation & geological history
Formed in lithium-rich igneous pegmatites through hydrothermal processes. Most specimens are from the Phanerozoic eon, often found in granitic intrusions where boron-rich fluids crystallize late in the cooling process.
Uses & applications
Used primarily in jewelry as a gemstone, as lapidary rough for carvings, and as a popular collector's mineral specimen. Pink tourmaline is also used in metaphysical practices.
Geological facts
Pink tourmaline is often called 'Rubellite' when the color is deep and saturated. This variety is pyroelectric, meaning it can generate an electrical charge when heated or cooled, which often causes it to attract dust.
Field identification & locations
Identify by the characteristic elongated, striated prismatic crystals of tourmaline embedded in a hard, glassy quartz matrix. Commonly found in Minas Gerais (Brazil), Madagascar, Afghanistan, and San Diego County (USA). Look for the vertical striations on the crystal faces.
