{"title":"Cuprosklodowskite","description":"\u003cp\u003e\u003cstrong\u003eCuprosklodowskite\u003c\/strong\u003e is a rare secondary uranium silicate, a copper-uranyl mineral of the \u003cstrong\u003esklodowskite group\u003c\/strong\u003e with the formula Cu(UO2)2(HSiO4)2·6(H2O). It forms by the oxidation of primary uranium and copper ores, typically as grass-green to yellow-green acicular or bladed crystals, often gathered into radiating sprays and crusts. Strongly radioactive, it is prized by advanced collectors for its vivid color and delicate needle-like habit rather than for size.\u003c\/p\u003e\u003cp\u003eThe species was first described in 1933 from the \u003cstrong\u003eKalongwe\u003c\/strong\u003e deposit in Katanga, then Belgian Congo, its type locality, and named — mistakenly, as it turns out — as the copper analogue of \u003cstrong\u003esklodowskite\u003c\/strong\u003e, itself honoring Marie Skłodowska-Curie. The finest specimens in the world come from the \u003cstrong\u003eMusonoi Mine\u003c\/strong\u003e near Kolwezi in the Democratic Republic of Congo, where bright acicular sprays occur on siliceous matrix alongside \u003cstrong\u003evandenbrandeite\u003c\/strong\u003e, \u003cstrong\u003ekasolite\u003c\/strong\u003e, \u003cstrong\u003eschoepite\u003c\/strong\u003e, \u003cstrong\u003euranophane\u003c\/strong\u003e, and \u003cstrong\u003etorbernite\u003c\/strong\u003e. Additional classic occurrences include the \u003cstrong\u003eShinkolobwe Mine\u003c\/strong\u003e and \u003cstrong\u003eKambove\u003c\/strong\u003e, also in Katanga, as well as \u003cstrong\u003eJáchymov\u003c\/strong\u003e in the Czech Republic.\u003c\/p\u003e\u003cp\u003eBecause well-crystallized, aesthetic material is confined to a handful of localities, documented Congolese and Jáchymov specimens are especially sought after by uranium-mineral and micromineral collectors, systematic silicate collectors, and anyone assembling a suite of \u003cstrong\u003eKatanga Copperbelt\u003c\/strong\u003e secondary uranium species alongside becquerelite, brochantite, and compreignacite.\u003c\/p\u003e","products":[{"product_id":"lz-uranium-cuprosklodowskite-0","title":"URANIUM CUPROSKLODOWSKITE – Uranium Silicate Crystal from Congo – Rare Mineral","description":"\u003cp\u003eRare natural Cuprosklodowskite specimen from Musonoi, Kolwezi, Lualaba, Democratic Republic of Congo.
