Description/Interesting Notes:
A terrific example of these rare uranium-bearing species from the Congo!!! This specimen consists of a matrix comprised of chalcocite and malachite that hosts vugs
of sharply formed, dark green crystals of vandenbrandeite in association with intense yellow guilleminite!!! There are numerous areas of
guilleminite throughout the matrix scattered throughout the matrix and, upon close examination with a loupe or scope, one can see some tiny well formed
crystals in protected cavities!!! The vandenbrandeite crystals are significant and much better than the pics show!!! The specimen hosts an area of
acicular malachite crystals with a few torbernite crystals scattered among them as well!!! There are some areas of crystalline chalcocite intergrown into the
matrix as well!!! There is a LOT going on with this specimen!!! This is older material that dates to the 1950's!!!
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!! MORE AUCTIONS WILL BE ADDED MONDAY NIGHT FOR A SPECIAL 3-DAY AUCTION, ENDING THURSDAY OCTOBER 27th!!!
