Uraninite occurs as a primary mineral in granitic and syenitic pegmatites. Well-formed crystals are rare but cubes, octahedrons and modified forms occur. Uraninite is also found as a high-temperature precipitate in hydrothermal veins, often as a crust exhibiting a botryoidal or granular habit. Uraninite is also found in sedimentary rocks.
This massive, blocky cluster of Uraninite, which used to be called Pitchblende, is radioactive being a Uranium-rich mineral and ore. This chunk features well-formed geometric crystals with a dark gray to blackish color. This piece comes from the Shinkolobwe Mine - known for highest-grade Uranium ores.

A beautiful example of galena with tiny red crystals of "ruby jack" sphalerite, on a chert matrix. Galena is not rare, but these old (all date before the mid 1960's) examples from the Tri-State district are by far my favorites-- the sharp edges, clean faces, and relatively "not busy" chert matrixes really set them apart from the modern Viburnum pieces, or for that matter, examples found pretty ...
The important radium sources were uraninite from the historic Joachimsthal mines in what is now the Czech Republic and the carnotite (hydrous potassium uranium vanadate) ores of western Colorado. By 1912, radium was the most valuable commodity in existence and cost $100,000 per gram—nearly $2.5 million in today's currency.

Specimens consist of vitreous luster, brown-black massive Samarskite-(Y), often accompanied by small amounts of a light colored matrix, probably massive Feldspar. Items 2572, 2575, and 2576 exhibit some partially developed crystal faces along with the massive Samarskite-(Y).
The granite pegmatites at Topsham have produced some of the finest Uraninite crystals known, although certainly not the largest. This crystal, contacted along the bottom, is a tabular, heavily modified cuboctahedron with good sub-metallic luster and brownish-black color.

Uraninite is found in many geographical areas, although mostly in small quantities. A classic European occurrence is Pribram, Bohemia, in the Czech Republic, which has produced fine botryoidal agglomerations. The occurrence of Katanga (Shaba), Congo (Zaire), has produced some of the finest and most lustrous crystals of Uraninite.
