Musonoi Mine, Kolwezi, Kolwezi mining district, Lualaba, DR Congo

Dimensions: 45 mm x 50 mm x 38 mm

Cuprosklodowskite: Cu(UO2)2Si2O7 - 6H2O, Hydrated Copper Uranyl Silicate.

Green flower of cuprosklodowskite on matrix.

Cuprosklodowskite is a rare uranium mineral formed from the oxidation of copper and uranium-bearing minerals.

Named in the mistaken belief that it was the copper analogue of Sklodowskite, which in turn was named for Marie Curie (née Maria Sklodowska), (1867 - 1934), 1903 Nobel Laureate in Physics, and 1911 Nobel Laureate in Chemistry.

Activity: microSieverts/hour: 13.6 (1 gram, fully aged).

A beautiful piece that, sadly, has to live outdoors.
