The pics pretty well convey here the stunning 3-dimensional crystalography of this specimen, featuring a large "doublet" cuboctohedron with a strangely elongated horizontal axis perched atop a smaller crystal showing more cubic and less octohedral faces. The large crystal is 5.5 cm across and is totally transparent and clean. The crystals stick out dramatically from the underlaying sphalerite matrix (crystallized), which you can look through the smaller crystals and see on the bottom, plus from the underside and sticking out around the edges of the lower fluorite clusters. The piece has a pale color, mostly colorless but with a hint of pastel green floating in the core. For overall geometry, this is one of the most dramatic pieces I have seen from the place, and REALLY leaps out at me.
