Exceptional, L-shaped Fluorite crystal intergrown with another Fluorite forms a strikingly unusual specimen. The Fluorites' good luster and nice gray-blue color are highlighted by sharp, first-rate, purple and blue bands. I have not seen a habit like this so well-formed from here. The aesthetics and unusual habit make this an outstanding small cab. It is one of the most dramatic of its style, I have seen, and really stands apart from the rest due to its shape and gemminess/transparency. The RCL collection number came off in cleaning, although it is surely Minerva Mine.
