Frequently asked questions
Is predominately blue tanzanite rarer than violet?
Tanzanite shows different colours from different crystal directions. Because the blue colour is usually located on the short axis of the crystal, it’s often more difficult to cut a large, predominantly blue gem. Cutters have to decide whether to cut a larger, predominantly violet gem or a smaller blue one. As a result, tanzanites that face up blue are rarer than those that are predominantly violet.
