An excellent rich specimen loaded with little yellow balls of Uranopilite full of acicular crystals to about 0.5mm. The Uranopilite is on orange crystals of Rutherfordine in groups showing elongated radial spikes like a sun. Great contrast and beautiful piece. Analyzed specimen with EDS spectra shown in provenance tab.

A very rich specimen with lemon drop-like crystal groups of Schumacherite to 1mm throughout the spongy matrix. I suspect as old as this specimen is since it was collected (ca 1880's) the Uranosphaerite is a bit dehydrated. It's a fabulous specimen taken from a group specimens from the Georg Gebhard collection.
