This natural bi-color tourmaline is cut in an elongated octagon shape and presents a deep, inky blue-green teal color that sits at the boundary between indicolite and verdelite. The stone is richly saturated with a dark, almost forest-teal depth that shifts between deep blue and forest green depending on the angle and light source. One small natural inclusion is visible at one corner, while the rest of the stone shows clean transparency for its deep tone.

Originating from Tanzania and fully untreated, this is a genuinely rare piece with a teal indicolite character that appeals to collectors and jewelry designers who work with bold, dark-toned gems. The elongated octagon shape makes it especially suitable for baguette-style settings or as a center stone in an art deco inspired ring.
