The blue color of tourmaline is known by the name indicolite. It is one of the rarest colors in tourmaline and fine blue and bluish-green specimens are sought after by collectors.

How much is fine blue tourmaline worth? The value of natural blue tourmaline can vary greatly depending on size, quality and color. Buying direct from AJS Gems you'll get the best value in the market.

Indicolites can range from light to dark saturated blue. Although color grading is a judgment call, I think many tourmalines sold as blue are misrepresented. In my opinion, an indicolite can be any shade or color as long as blue predominates. For example, most indicolites have some degree of green in them. (See below). I would call a blue/green stone with dominant blue a blue tourmaline. If the green dominates, I’d call it a green tourmaline or verdelite. Generally, blue brings more money, which explains why some in the trade are eager to call blue/green tourmalines indicolites even if the green predominates.
