A translucent plate of unusual quality in terms of both its aesthetic horizon at the top, and the translucency of the fluorite itself. Most larger "bubbles" are thickert, and so transmit little light through the core. This one, however, has formed thinly to start with with the bubble rising only so much from teh crust as to make it look spherical when in fact it is hemispherical. For my tastes, this is one of the best specimens of this material I have seen come out in a trickle since they first appeared at Munich 2006. I have seen several hundred specimens now, at all kinds of price points both direct at the mines and from resellers, and in the end I did find a source in China to buy them directly - this is still among the best I could obtain.It is pristine, beautiful, an djust plain unusual material!
