| Mineral: | Bismuth with Dolomite and Erythrite |
| Locality: | | Gang Opal, level 371, Niederschlema, Bad Schlema (Schlema), Schlema-Hartenstein District, Erzgebirgskreis, Saxony/Sachsen, Germany |  |
|
| Dimensions: | 9 x 11 x 8 cm / main crystal: 2.2 cm. |
| Description: |
Mass: 1250 g
MIM number:2151
Group of very sharp and separated gray bismuth crystals, with small scattered white dolomite rhombohedra offering a beautiful contrast. Some faces of the bismuth crystals have a hopper formation. The base is coated with micro-crystallized erythrite of purple-red color, which is characteristic of this mine. This sample was found as is and was not acid-etched to free it from its gangue as shown by the perfect state of the dolomites.

Translucent leiteite composed of stacked quadratic crystals of nacreous appearance on a black granular matrix. Orange legrandite crystals (the largest measuring 0.7 cm) have grown on some sides of the leiteite, adding to the contrast of the sample. Legrandite (an arsenate) is rare in Tsumeb, and it is even rarer to see it associated with leiteite (an arsenite), as both species result from two different oxidation states of arsenic.

| Description: |
Mass: 14150 g
MIM number:2155
Nicknamed "The Giza Plateau" for its striking resemblance with the famous pyramids of Egypt. Huge perfectly formed transparent octahedron of burgundy-red color, with smooth faces, on a plate made of prase quartz crystals (the color of which is due to green asbestos inclusions), with four small octahedra nested on its faces. Ten other small pink fluorite octahedra developed on nearby quartz points. This unusual configuration (large octahedron and second generation of smaller octahedra) is the signature of this exceptional discovery in Inner Mongolia. Löllingite covers certain quartz points, and lamellas of white calcite have developed at the back of the large octahedron.

Like all MIM specimens, this piece is just incredible! For sure one of the best and largest Gremmelsbach pyrolusites ever found, I have never seen a piece that large and that good. At first sight I thought it was a Wuning Mine stibnite ;-)

Nicknamed "Emerald City" because of its striking resemblance to the mythical city of the movie "The Wizard of Oz". Group of large parallel stalactites (the largest measuring 44 cm) of a beautiful, very shiny green, on an earth-colored matrix (it is probable that this set was detached from the ceiling of the vein and therefore pointed downwards). The stalactites give a “wet” impression under lighting due to the microcrystals which form their surface. It is rare to find such a large and aesthetic group in this condition.

Perfectly formed and symmetrical octahedron with sharp points and faces augmented by very flattened 6-sided rounded pyramidal shapes. The crystal weighs 92.58 carats, is light yellow, and is surprisingly clean (a single 1mm inclusion is visible very close to the surface, the interior being completely clear). It is astonishing that this crystal, found in the diamond-bearing gravel of a river, has survived so intact.

Aesthetic group consisting of several copper “feathers” with perfect natural brown patina. Crystals are elongated along one or more of the cubic axes with repeated growth along their lengths, which results in this 3-dimensional arborescent form with "branches" at right angles to the "stem". It is rare to have so many “feathers” together in one piece: usually this locality just produces single copper “feathers” with no matrix.
