Perfectly formed crystal of light blue translucent sodalite (hackmanite variety) on a white marble matrix. The crystal has all its faces and is smooth and shiny (which is not common for these sodalites released from the marble in which they were formed). In addition, it shows a very strong orange fluorescence under long UV, and a pale yellow phosphorescence.

Large, cream-gray beryllonite wheel developed on a matrix made of 7 large, well-formed white pollucite crystals (the largest measuring 18 cm). It is very unusual to find these two rare minerals in association, let alone in such a large and well-formed sample. The whole is reminiscent of a reclining lion whose body and legs are pollucite and the mane beryllonite, hence the nickname "The Lion of Kashmir" given to this piece.

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.

| Description: |
Mass: 306 g
MIM number: 2212
Double terminated quartz with multiple secondary terminations. This crystal contains an uncommon 4-phase inclusion consisting of a gas bubble trapped in the petroleum, the yellow petroleum itself, a darker brown organic material, and black carbon inclusions. The gas bubble formed as the petroleum contracted more than the quartz after cooling, thus pulling a vacuum within the fluid which vaporized the lighter cuts of the petroleum and created this bubble. This sample is highly fluorescent under both short and long wave UV.

In fact, close examination shows that the terminations of these crystals are cream-white colored scepters primers.

It is the largest crystal to come out of an aberrant pocket in this mine which is not at all known for this mineral (the other bertrandite crystals that have been found there are much smaller and have been cut).

The likely geological history of the formation of this superb sample can be easily read by inspection: A large crystal of red topaz measuring at least 13 cm formed first, then got cleaved into 4 pieces by the tectonic deformations of the medium in which it was found (hence the nickname "the rocket" as they look similar to the stages of a spatial step rocket). These were subsequently displaced from their initial position by the natural movements of the medium and then “frozen” in calcite (more precisely in a light-colored tectonic breccia, which formed above a grey carbonatite). The 4 pieces do not show the same width: the section of a topaz crystal being rectangular, these pieces probably rotated before getting frozen. Part of the breccia was removed to expose the pieces of topaz that show a superb red color that is very rare for this mineral (coloration due to chromium which also imparts a strong UV fluorescence, and to the absence of natural radioactivity which would have transformed it into a sherry color as is the case for the Brazilian imperial topazes).

Beautiful crystal totally transparent and without veils, smooth and shiny, with a perfect top termination. The crystal is trichroic even if the colors are a little pale (the crystal has not been heated): the purple is well expressed, the blue is not very saturated, and the red is rather pink. The advantage is that this crystal is perfectly visible without special lighting, and that under polarized light (such as that coming from a LED screen) one can see a whole series of amazing colors by rotating it.

The main crystal of this sample, considered very large for this species, is a beautiful translucent light amber color. Its surface is composed of abundant vicinal faces (the position of which varies very little from that of a fundamental plane of the form). The major rhombohedral face is aesthetically positioned (facing the front of the specimen) and shows a subtle four-petaled rosette pattern. The intersection of the rhombohedral faces reveal a subparallel offset of crystals, producing the satiny reflectivity of the vicinal faces. The sides and back of the specimen have similar large smithsonite crystals.

Two crystals in the shape of a pentagonal dodecahedron, slightly shifted and parallel, well formed and considered large for the species. This specimen was found by serendipity in a wooden treasure chest under a house built in the 1630s. It was therefore probably mined before the element cobalt it contained was identified.
