Physical properties
Hardness: 7-7.5 (Tourmaline) / 7 (Quartz); Color: Pink to rubellite inclusions in white/clear matrix; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: Indistinct; Specific Gravity: 3.0-3.3
Formation & geological history
Formed in granitic pegmatites through hydrothermal processes during late-stage igneous cooling, often where lithium and boron are concentrated.
Uses & applications
Used for carvings, tumbled stones, jewelry (cabochons), and as a popular metaphysical or collector's specimen.
Geological facts
The pink color in the tourmaline is caused by natural irradiation or manganese impurities within the crystal structure during formation.
Field identification & locations
Identified by the needle-like or massed pink hexagonal crystals embedded within a translucent white quartz matrix. Found commonly in Brazil, Madagascar, and Afghanistan.
