Species: Uranophane & Rutherfordine ps. Uraninite Crystal Locality: Lukwengule, Morogoro Region, Tanzania Dimensions: 3.0 cm x 2.8 cm x 2.7 cm, 104 grams
Outstanding, very large sharp cubic uraninite crystal that has been extensively replaced by uranophane and rutherfordine from the classic and uncommon locality of Lukwengule, Morogoro Region, Tanzania. These amazing uraninite psuedomorphs are true classics of uranium mineralogy and this is perhaps the best (certainly the largest) I have ever seen! Ex. Eric Quinter Collection. Rare!!
