Uraninite with Uranophane and "Gummite" (ex Foote Specimens)

Item Description

A cool mixed box of black Uraninite, pale yellow Uranophane and beige-tan "Gummite" which is classified now as a mixture of Boltwoodite, Clarkeite, Curite, Kasolite, Soddyite, Uraninite and Uranophane, but was a valid species at one point in time. There are over a dozen pieces in the original A. E. Foote box, which states that the specimens were examined by "W. M. F.". If you collect old Foote material, or just classic documented U.S. minerals, don't miss out on this box of specimens.
