A brilliantly lustrous, intensely gemmy, "yellow tanzanite" with a unique yellow-green color that comes only rarely from these famous mines for blue tanzanite. The color on these, at their best like this one, is really more like brazilianite than any other zoisite find you might have seen. Crystals of this material tend to be very glassy and lustrous, as this one. It is complete all around and has a superb termination.
