A specimen of surpassing quality, with both gemminess and GEM VALUE going for it. This is a NATURAL tanzanite without having been heated to enhance the blues at the expense of the red hue. This piece is the most strongly trichroic tanzanite crystal I have ever had to offer. It glows with rich colors: blue, purple, and particularly red/maroon along the c-axis. The pictures only approximate the intensity. Moreover, it is a super-sharp, fully terminated crystal of the highest quality in terms of sharpness of form and fine termination. It has luster like glass. this is a KILLER and of such quality that it is a miracle it was not cut for facet rough (certainly, though, it could be). This is the finest tanzanite I am aware of that is currently on the open market - I have seen 3 larger and more expensive (one heated, among them), but this is the finest in overall quality. I obtained this from Ed in a deal some time ago and he told me at the time that he had gottne this by request, upon asking Bryan Leees to find him the best possible miniature at the time (mid-1990s).
