This comes from the Type Locality of Francevillite and Curienite, home to the only known Natural Nuclear Reactors! Research Oklo Natural Reactor if you do not already know about this fascinating discovery. Rare crystallized and highly sought after Francevillite. Likely associated with Curienite and other rare minerals.
Very richly crystallized with other unidentified minerals including strange "hairy" formations. Very unique! Truly an excellent specimen and something that I can hardly ever find, even if I wanted to pay unlimited money for it.
