Compreignacite was found on this piece when I broke a sample off for analyzing. Becquerelite, Schoepite Gummite with dense powerful Uraninite. Yes I hit a late 1800s to Early 1900s piece of material with a hammer. Now more people can share in its glory! I have one big piece left and so I will be keeping the antiquated label.
This is likely the sort of material that the Curies were working with in the Early days of Uranium mining in Bohemia!!
Historic as it gets.
