Impress any Uranium enthusiast instantly. 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. There  is rarely a piece of high grade ore on the market and I was lucky enough to acquire all of the remaining pieces from the last find of ultra hot and dense Uraninite.
The material from the original 14 ft thick vein of Pitchblende was hauled away and crushed for Uranium production and little survives. This is truly beyond a Museum Grade specimen from the Holy Grail of Uranium Mines as far as the US localities go. Definitely in the top ten if not top 5 locations for Uraninite in the whole entire world and likely one of the largest and best privately owned specimens in existence for this locality. The secondaries require analyzing to understand the full scope of the minerals that have formed on the Uraninite.
Beautiful under magnification. Forgive my poor microphotos while my macro set up is in storage! Serious buyers can ask for video and better pictures and I will be happy to oblige.
