More Information




Indicolite is a blue variety of Tourmaline, that is usually, but not always, the Elbaite variety of Tourmaline. A true Indicolite color is a light to dark, saturated blue. Of course a true Indicolite will be a pure blue, but the name has come to be used for just about any shade of blue ranging from grayish blue to violet-blue.

Indicolite was named in 1800 by Brazilian mineralogist José Bonifácio de Andrada e Silva (1763-1838). The name Indicolite is from the original indigolite, which is from the early 18th century French word indigo, meaning deep blue color, and the Greek word λίθος, (lithos) meaning stone. The French word indigo referred to a blue dye obtained from a plant of the genus Indigofera. Indigofera is a large genus of over 750 species of flowering plants belonging to the family Fabaceae, commonly known as the legume, pea or bean family,
