This is a whopper of a large crystal of tanzanite, showing an exceptionally sharp, steep termination and good color throughout. Uniform blue color like this indicates that, like most specimens of the material, it has been heat-treated to intensify that hue. However, this is considered par for the course for most tanzanites and is one of the few times in minerals I accept such treatment for the beauty it creates, so long as it is disclosed. The crystal is complete on front and sides, contacted only a bit on the backside. The steep termination is awesome from any angle and draws the eye. This is a giant for the price, too, considering what has been available of late (not much!).
