Indicolite

Indicolite — Blue-Green Tourmaline

The word Indicolite is derived from the Latin word "indicum," meaning indigo or blue, and the Greek word "lithos," meaning stone. Indicolite is a type of tourmaline that belongs to the elbaite group, which is known for its complex chemical composition.

Color

Blue tourmalines are found in different shades, ranging from light blue-green to rich dark blue. In the gemological community, there is a debate from time to time about how to categorize stones as indigolites. More often the debate is about the acceptability of a certain amount of greenish hue in the samples in question. Visually pure, bright-blue tourmalines with minimal or no green are considered the rarest, and their price is comparable to that of the Paraiba tourmalines. The value of specimens is determined by their color and purity. Turmalines with bright blue coloring are less common and cost much more than the common green and yellowish stones.
