Tourmaline

Tourmaline is a diverse borosilicate mineral group offering collectors remarkable variety in color, crystal form, and geological significance. These trigonal minerals exhibit an extraordinary spectrum of colors—from black and blue through green, pink, red, and colorless—with some specimens displaying multiple colors in single crystals (polychromatic tourmaline). Tourmaline specimens are essential for collections exploring mineral diversity, crystal structure variation, and color phenomena in minerals.Tourmaline deposits occur worldwide in granite pegmatites and metamorphic rocks, with major sources in Brazil, Madagascar, Afghanistan, Maine, and California. Each tourmaline variety—elbaite, schorl, dravite, liddicoatite—forms in distinct geological environments and displays characteristic color and properties. Notable tourmaline-producing localities yield specimens with size and perfection rivaling fine gemstones.
