Impress any Uranium enthusiast. There will not be another one of these amazing specimens. This is the best material from a long ago exhausted mine that created the Uranium boom in Utah. The Mi Vida Mine yielded up its goods about 80 years ago and lies in a state of collapse and without any ore. It will live on in history books and collections. 
This is truly beyond a Museum Grade specimen from the Holy Grail of Uranium Mines as far as the US localities go.  The secondaries include Uranopilite on a thick vein of High Grade Uraninite that runs through the sandstone. Beautiful under magnification.
