Mass: 511 g
MIM number:1969
Group of parallel gray-black crystals on a rocky matrix. The crystals of this rare species are generally lying against the matrix. It is uncommon to find them protruding from it as visibly as on this specimen.

MIM number:1971
Beautiful divergent sheaf of blue, perfectly formed and pointed transparent crystals, developed around a large, richly faceted main crystal, inside a geode. The shape of these crystals is unusual for this mine, which generally produces crystals with chisel shaped terminations. The celestine crystals of Madagascar, among the most beautiful known, are found in geodes that are old gas bubbles formed by the decomposition of organic matter contained in 65 million years old marls and sandstones.

Doubly terminated, perfectly formed yellow crystal on a matrix of hard limonite with a smaller crystal jutting out from it at oblique angle. The terminations of these crystals are transparent. A tuft of fine and transparent crystals has developed on the matrix nearby. It is rare to find crystals as well formed and intact on matrix: this mine has often produced isolated crystals or friable and unstable matrices.

I too am a big galena fan and when I first looked at the photo my first impression was - "I have one like this - why would the MIM want it?" - THEN I looked at the size of the specimen and the size of its blinding crystals - OK, it may be the best in the world.

That is what I call the LaMIMMME - the Looking at MIM Museum Minerals Effect:
You take a look and you are stunned by the beauty and perfection of the specimens ... than you read the size information and you are even more stunned and completely awestruck when you realize the dimension of these masterpieces.
Congratulations, Bob, you have been successfully LaMIMMMerized ;-)

A group of bright, very sharp, amber-colored transparent crystals on a cream-colored matrix made of hardened mud riverbed. A small crystal on the right has "lifted" a matrix tongue to form. This sample is unusual as it consists of a bouquet of crystals whereas usually the crystals of this provenance are isolated.

Sharp hexagonal prism of calcite which has been completely coated with small amethyst crystals on top of which a large, superb, translucent elongated rhombohedral calcite grew later. What seems to be another elongated calcite rhombohedron parallel to the large one on the left has been completely coated with larger amethyst crystals, likely from a different growth phase. This entire masterpiece specimen, with its perfect proportions, was attached to the basalt geode in which it formed by the thin elliptical, horizontal section on the bottom front!

6 well-formed cumengeite tips developed in epitaxy on the faces of a boleite crystal, all forming a symmetrical sample of beautiful blue color. A smaller cumengeite (4 mm wide) has formed on the lateral face of one tip, which earned this sample the nickname "Kangaroo" in reference to this animal which carries its young in its marsupial pocket.
