Relatively sharp pseudomorphed crystals to about 1 cm, of Uranophane pseudo. Uraninite from this unusual location. Nice for the replacement from any locality, too!
This large, rich specimen has THREE species for which this is the type locality: Masuyite (in red spherical aggregates), Fourmarierite (dark red/umber crystals underlaying the BQ and embedded in the matrix), and superb, large sprays of Becquerelite with crystals to a whopping 5mm . The matrix is uraninite. Many are freestanding! In person, this is a beautiful specimen worthy of a display shelf, but its also an important combinatorial piece.
TYPE LOCALITY material of these VERY rare species! The kamotoite are the vibrant yellow crystalline sprays with individual flat-laying crystals to 6 or 7 mm, accented by microcrystalline uranophane around their periphery and by a small bit of subcrystalline Astrocyanite (blue). Aesthetic, rich specimen, of some significance. TYPE LOCALITY for both Kamotoite and Astrocyanite
A Large and colourful specimen with an unusual combination: bright yellow Uranophane crystals are filling a large vug of green Cuprosklodowskite crystals. Very interesting about this piece is that the Cuprosklodowskite crystals are partially imbedded in the Uranophane crystals and on some crystals, the green Cupro is passing THROUGH the terminations of the Uranophane crystals. Thus, this is not pseudomorphing, but growth together in the same pocket! At a close look, one can observe that many of the Cupro crystals are terminated, which is not often seen. This piece was recovered during the removal of the U-dump in the early 90ís. Musonoi has ceased producing minerals since then.
A Small but extremely rich specimen of Uraninite covered with powdery, microcrystalline yellow Uranophane. On the Uranophane one can see a few straw yellow Studtite crystal clusters up to 4 mm in size. Shinkolobwe is the Type Locality for Studtite, a mine closed since decades. Valid , photogenic studtites are NOT common and so this is an extremely rare chance to own one for a good price range, that is something visibly interesting.
Although this is "just" a Small specimen of Uraninite it is well covered with Studtite sprays up to 3 mm on a bed of Uranophane with orange Fourmarierite. The contrast is amazing and helps to make this a significant, photogenic, Studtite specimen among the best youc an obtain. Fourmarierite is best known as red pseudo hexagonal crystals but also as orange needles or "grains". On this specimen it is seen as this orange form which is much rarer but mostly overseen or taken for Curite and thus mislabelled if ever it wsa found in some collections. Shinkolobwe is the Type Locality for the Studtite and the Fourmarierite, a mine closed since decades. This superb combo specimen is a chance to own each, in beautiful mix, at one stroke. We think there are few such validated specimens of these rare species out there, of quality, let alone on the same specimen.
