Mogok, Sayaing district
5.9 x 3.6 CM (small cabinet/ large miniature)
A single sizable (3 CM) crystal of rich green Chrome tremolite sits on a calcite matrix. The crystal form is impressively sharp for one of such size, this is not the typical "blob" of tremolite! Great color and gemmy on thin edges, these are not common in general and rare in such aesthetic specimen.
As a rule, black Sphalerite is not a very desirable mineral, but this one is something special! Lusterous and sharp glassy Sphalerites to almost 3 CM are decorated with treelike growths of slender quartz crystals. In great condition and with killer esthetics, the Sphalerites are well positioned and show complex growth hillocks on many faces. Careful examination finds only minor edge wear on some sphalerites, nothing distracting from the impact of this piece. Great for this specie and exceptional for this famous mineral region!
A very old and very fine Tri-state classic! Ex collection of the Arizona-Sonora Desert Museum, This is a true top shelf specimen. Sphalerites here reach to 4 CM and are exceptionally well formed. The smaller crystals are a fine ruby red (rubyjack) while the larger ones are darker and coated with chalcopyrites. Some faces are noticably irridescent and over all the luster is outstanding. The only damage is at the outer edges where it would be expected, the display face is pristine, three dimensional and very esthetic. The old Tri-state area produced a lot of materials in its time, but this quality was excellent even in its heyday.
An exceptional Spinel galena from the John Marshall Collection. Textbook perfect clusters of Spinel twins reaching 4 CM are esthetically placed on a complex matrix of fine quality Chalcopyrites and minor quartz, sphalerite etc. One large Chalcopyrite (2.4 CM) is also a textbook perfect crystal and is perched at one end of the specimen. There is a lot of Galena from Dalngorsk but fine spinel twins from there have become quite rare (they were never common in top quality). This one has both excellent condition and esthetics.
Fantastic array of fine, orange red Sphalerites covering the contrasting matrix. Formerly in the John Marshall collection with his labels and catalog card, he obtained this piece in 1984. This type and quality has not been available for many years now. Esthetic and with uncommon color, this is very eyecatching. Most crystals are in perfect condition except near the outer edges. A very good investment for any collection.
A single, big, elongated chalcopyrite crystal showing fine striations and luster. Most faces are perfect and shiny, but there is slight chipping on a few edges, not significant given the size of the crystal. Although Chalcopyrite is a common mineral, crystals that are complete of this size are rare. Madan has produced a few superb examples.
Galena on Sphalerite
Krushev Dol Mine, Madan, Rhodope Mts.
8.4 x 6.9 CM (cabinet)
A sizable (4.4 CM) galena sits in a sea of lusterous Sphalerites. Clean and esthetic, the Galena has some hoppered areas and elaborate growth phase lines. Nice contrast and no damage on the display side.
Chumar Bakhoor, Hunza Valley
Gilgit, Northern Areas,
5.1 x 4.9 CM (miniature)
A single pink octahedron with frosted faces and very good transparency. The crystal is contacted on the back and base and has some adhering muscovite. The display side however presents well with sharp faces, clean edges and good light pink color. A good value for a crystal of this size.
