Uranosphaerite with Schumacherite from Schneeberg dist., Erzgebirge, Saxony, Germany
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.
