Uraninite -large cube
Cardiff U Mine, Wilberforce, Halliburton
8.8 x 6.2 x 5 CM (cabinet)
A large Fluorite and Calcite matrix with a very big (1.6CM) single cube of Uraninite well exposed on the top edge. This cube is a bit unusual as it shows some corner modifications. The Luster is moderate to dull as were most of the larger crystals from this area, and there is a crack visible from some angles but the crystal seems still quite solid. As this is a quite radioactive specie there are limits on shipping but we can make hand delivery to major shows or use a special courier (more expensive) for shipping. This locality has been reclaimed and there will never be more of these.
