Microcrystalline red-orange billietite microcrystals with rich coverings of dark green Vandenbrandeite crystals, amongst malachite . Not so great a billietite, but a very good Vandenbrandeite for the price and the billietite is a bit of a bonus
ex. Bill Pinch ex. Charlie Key
A really rich specimen , beautiful, with orange curite microcrystals completely covering the Vandenbrandeite within protected vugs on 2 faces of the specimen. The rest of the specimen shows solid Vandenbrandeite - and is thus among the richest examples of the species I have seen. This can, obviously, be broken up into several pretty good specimens of both minerals, and sold fo rmor emoney
12.2 x 8.2 x 6.1 cm. Vandenbrandeite usually occurs as microcrystalline druses, but here we have a large cluster measuring approx 1.7 x 1.5 cm, with eye-visible crystals to 6 or 7 mm in size in a rich aggregate.
6.9 x 6.7 x 2.8 cm. A representative species specimen of cuproskodowskite Cu[(UO2)(SiO2OH)]2 - 6(H2O) and fellow uranium mineral vandenbrandeite Cu(UO2)(OH)4 from the Musonoi Mine. The Bob Byers label accompanying this piece shows it to have been mined in the 60s, and that he acquired it from Bill Pinch.
9 x 6 x 6 cm. A large Cuprosklodowskite vug filled with very well formed dark green Vandenbrandeite crystals. These are dusted over with the rare uranium selenite Guilleminite in good yellow crystals. Such association is not common. Musonoi is the type locality for Guilleminite and in this specimen the crystals are very well formed but under one millimeter.
5.5 x 2.2 x 4 cm. This is an unusually good specimen of large Vandenbrandeite crystals, well isolated on matrix. Well developed dark green Vandenbrandeite crystals gathered together in unusual "bowtie" shapes, with small yellow Kasolite flakes decorating them. Kasolite occurs in Musonoi in this form and is easily recognizable because it shows a highly pearly lustre. Some small yellowish frosted Baryte crystals are associated. The Vandenbrandeite bowties reach 5 mm.
11 x 5 x 4 cm. A fine combination piece of green Torbernite crystals associated with typical green Cuprosklodowskite tufts and yellow Sklodowskite aggregates. The Torbernite crystals looks dark green but on close examination, one can see that they are covered with thousands of doubly-terminated Vandenbrandeite crystals. Some of them are also implanted in the Cuprosklodowskite tufts. The Torbernite crystals reaches 6 mm on edge. The Vandenbrandeite crystals are in the 1-2 mm range but very sharp.
4.8 x 3.2 x 1.9 cm. Here we have a very interesting specimen of Type Locality Vandenbrandeite with accent of pale green Cuprosklodowskite. The very fine Vandenbrandeite crystals are reaching 3 mm and are quite large for the locality. Vaes discovered these minerals in the early 1930’s in this remote area of Katanga (Kalongwe is located 60 km south of Kolwezi and was not very well accessible in that time because it lies in full jungle), and some few came back with his expeditions. This is why the deposit has never been mined, and will probably never be mined. And, so very few specimens reached the collectors. In sum this is not only a superbly crystallized example of this species but is also a very good and rich locality piece for the collector who values locality data and rarity. Few are likely to exist.
4.0. x 3.7 x 2.5 cm. This is a fantastic specimen of Cuprosklodowskite with Vandenbrandeite from the Type Locality for both species. The very good Cuprosklodowskite crystals are very large for the locality. The Vandenbrandeite builds sheaves to 8 mm, huge for the locality. Vaes discovered these minerals in the early 1930’s in this remote area of Katanga. Kalongwe is located 60 km south of Kolwezi and was not very well accessible in that time because it lies in full jungle. This is why the deposit has never been mined, and will probably never be, so very few specimens reached the collectors.
10.1 x 5.3 x 2.8 cm. This rare Copper Uranyl Hydroxide is best known from the various copper deposits in the Congo, and was first discovered in 1932. The species is named after Pierre Van den Brande a geologist from Belgium who worked in the Congo (Zaire). The intense deep emerald green color of these crystals along with their relative rarity is what attracts collectors. This specimen is filled with small sparkling crystals of Vandenbrandeite with Malachite on matrix. Ex. Richard Kosnar Collection.
Microcrystalline red-orange billietite microcrystals with rich coverings of dark green Vandenbrandeite crystals, amongst malachite . Not so great a billietite, but a very good Vandenbrandeite for the price and the billietite is a bit of a bonus 3.3 x 2.9 x 2 cm
A super thumbnail, that displays a large upper area covered in Vandenbrandeite. 2.2 x 1.3 x 0.9 cm
A really rich specimen , beautiful, with orange curite microcrystals completely covering the Vandenbrandeite within protected vugs on 2 faces of the specimen. The rest of the specimen shows solid Vandenbrandeite - and is thus among the richest examples of the species I have seen. 5.6 x 5.5 x 4.3 cm
Vandenbrandeite usually occurs as microcrystalline druses , but here we have a large cluster measuring approx 1.7 x 1.5 cm, with eye-visible crystals to 6 or 7 mm in size in a rich aggregate. The association on the bright neon-green Cuprosklodowskite is gorgeous. A significant concentration of this rarity, and beautiful as a specimen overall.
