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.
An older piece (60's vintage) from the John Marshall collection, this is distinctly different from more recent materials from Naica. Clear, transparent Fluorites are well placed on a contrasting matrix. The crystals are undamaged, bright, gemmy and have slightly curved faces. Displays very well, this will be a great addition to any Fluorite collection.
Metatorbernite with Kasolite
stock #8 -13 AFR-909
Musonoi Mine, Kolwezi, Western area
Democratic Republic of Congo (Zaire)
6 x 4.2 CM (small cabinet/ large miniature)
Brilliant sparkling crystals of emerald green Metatorbernite fill a vug nearly 4 cm across. Tiny but eye-visible crystals of Kasolite are scattered inside as well. In excellent condition overall, these Uranium minerals make a brilliant display on this piece. Shippable worldwide by Fed X this will be sent wrapped in lead foil. Good value in a very displayable radioactive.
A gemmy 4 CM aqua in perfect condition is penetrating a 4.8 CM albite crystal sitting on Muscovite. From the now famous Mt Xuebaoding area, this is a fine combo piece. Unusual relationship is prominently displayed in a very esthetic specimen. There are a lot of Aquas on the market from this area, this one is distinctly different and nice.
