RM1887   Curite and heterogenite
Pb3+x[(UO2)4O4+x(OH)3-x]2·2H2O

Very rich curite specimen, with some intense orange color crystals and the rest black due to being coated by heterogenite. The sample comes from the former Coune collection and according to its owner was adquired from the 90s, but specimen could be older. Curite crystals are disposed in a very contrasted way on the white matrix. From the type locality for the species.

RM789   Curite with soddyite
Pb3+x[(UO2)4O4+x(OH)3-x]2·2H2O

Small but interesting specimen of curite that presents groups of brilliant acicular prismatic crystals with an intense orange color. Observed under the microscope we can see that they have transparency and are accompanied by yellow crystals soddyita. This radioactive mineral is named after Pierre Curie (see wikipedia) and this sample is from Shinkolobwe, the type locality for the species. A chance to get a piece with curite crystals.
