Blue Tourmaline
The Tranquil Blue Tide of Calm
Also known as: Indicolite
About the stone

Blue tourmaline, commonly called indicolite, ranges from pale blue to deep indigo and blue-green and usually belongs to the elbaite species of the tourmaline group. Its first discovery is uncertain, but Brazilian mineralogist José Bonifácio de Andrada e Silva named indicolite in 1800, drawing on the word for “indigo”; historically, tourmalines were often mistaken for other gemstones before mineralogical identification improved. Important sources include Brazil, Afghanistan, Namibia, and Nigeria, while Brazil’s vivid copper-bearing Paraíba tourmalines became famous following discoveries in the late 1980s. In modern crystal lore, blue tourmaline symbolizes honest communication, emotional balance, and calm reflection.

Like all tourmaline it becomes electrically charged with heat or pressure and may attract dust, so wipe it regularly. Avoid ultrasonic cleaners, steam and sudden temperature changes.
