Description

A spectacular slab of uraninite from Argentina!   This specimen is a thick, dense slab of uraninite with bequerelite veining, and partially crystalline bequerelite along the edges of the slab.   Very heavy, and very hot.   International shipping charges will need to be higher on this one.   This specimen was recently deaquisitioned from the radioactive mineral collection of the legendary Dave Wilber, who acquired it in trade with Yale University.   Unfortunately, no labels accompanied the specimen.
