Extremely high-quality green fluorite, for the locality, perched atop a matrix of sulphides nad rhodochrosite. There is some possible pseudomorph casts under the fluorite, as you can see. Classic old material, and beautiful!

This pastel green, sparkling fluorite, exhibits unusual penetration twinning that APPEARS to be the product of two spinel-twinned crystals exhibiting some complex intergrowth between themselves. I don't know for sure...NEVER seen anything like it! The twinning actually appears to be more like cinnabar, which often exhibits star-shaped radial twins. The fluorite crysatl is almost 4 cm in length so this is a full miniature, and it is complete ALL around as well as perched on a small bit of muscovite matrix. This really puzzles me! To that end, it is all the more valuable intellectually as well as for its striking symmetry. This is a unique piece, and a competition quality miniature of fluorite from ANY locality.

Named after Orlando J. Benston, an ore dressing metallurgist with the University of Illinois, this is a very rare and COMPLEX carbonate species that was found only sporadically, i nsmall pockets, in the odler days of this mine. This is a niec specimen showing the paragenesis of the mineral, on altering fluorite matrix.
This is an unusual specimen in that it is a complete floater: a crust of translucent, pastel pink, inetergrown fluorite octahedrons to .5 cm across, COMPLETELY covers one face of a flattened, gemmy, light smoky, quartz crystal. The quartz crystal measures 8 cm across and again, is complete all around. The fluorite is preferentially only on one side, while the back of the specimen is the flat major face of the quartz crystal. VERY RICH AND COLORFUL with lots of pink for the price!
This combo piece features several cubes of fluorite, to 2.8 cm across , which have been coated by drusy, lustrous pyrite crystals. All this is aesthetically perched on a lustrous, radiating knoll of quartz crystals, reaching 1.0 cm across. COMPLETE ALL AROUND and brighter in person! An unusual yet interesting Moroccan piece!
The best small cabient from the find to date, in my opinion; this is the piece I showed at Munich that was illustrated in the Mineralogical Record report from the show. It features a gorgeous 3.5-cm dodec of fluorite perched atop a stalactitic cluster of quartz points. Desmond Sacco obtained this piece while travelling in South Africa, and brough tit to the show where he exchanged it with me. The pics say it all, except that i should add it IS complete all around!
Light green, translucent, satiny , fluorite has grown all around a thin slice of rock on this extremely rich locality specimen. I have not seen a more richly covered example of fluorite from teh locality. The best viewing side exhibits interlocked crystals to 1 cm across, and two knobs or rosettes of fluorite, the largest of which is 2.5 cm across.
This is a gracefully curved specimen of matrix which displays about a dozen SHARP AND GEMMY fluorites to 2 cm, showcasing deep internal phantoms of a vivid purple color! This habit and style is NOT common from the mine, and is much more vivid and bright in person.

A glittering, attractive combination specimen featuring a gemmy, clear fluorite crystal perched on a pedestal of galena crystals, and itself draped gently by a glistening coating of sparkling white calcite. This is a striking combo piece from a localitythat, while not quite defunct, now longer produces this assemblage.

A very strange Illinois specimen that is evidently an old specimen, said to have come from surface workigns near the mine and from a well-known Illinois collection. Deep purple cubes, some possibly pseudomorphosed (associated with a yellow mineral that turns out to be Smithsonite), occur on matrix. The largest of the lustrous, translucent, cubes is 1.5 cm across. With this mining district kaput, good to great specimens will become rarities. NOTE: FROM THE TOM WIESNER COLLECTION, NOT ZINN. got mixed into the update, though. NOTE: according to Ross Lillie, this weird find was a single boulder about two-three feet across with pockets inside. It was found in the Spar Mountain area with outcrops on the side of a hill. He assumes there where maybe a couple of dozen specimens. The find wasen't anything important in 1959 so that probly why there was no record.

This is a truly unusual and attractive mineral specimen which exhibits THREE generations of fluorite. Deep green, frosted, octahedrons, up to 3 cm in length, are topped by a layer of drusy purple fluorite, which, in turn, appear to have colorless crystals, to .5 cm, epitactic on the corners of the underlying octahedral crystals. All I can say is WOW!

Translucent, rich pink rhombs of rhodochrosite, the largest of which is 5 cm across, are studded with stunning, gemmy, light-purple, cubes of fluorite to .6 > also accenting the red color are 1 cm, sparkling, colorless quartz crystals. There is only trivial edge wear and a small 4 mm spot of minor damage to the very rear edge, at the visual periphery of the large rhomb and to the back from its front angle of display; but that is to be expected for such a soft mineral and a crystal of such size. There are no repairs or plastic fill, which is notable and also quite unusual for a specimen of this size and exposure. The crystal is very 3-dimensional, and perched as if upon a natural pedestal of smaller crystals and a big of galena-rich matrix. The overall effect is stunning , and there is a lot more sparkle and color flash to the piece in person than you gather from teh picture. Now that the Sweet Home Mine is closed permanently, specimens of this quality are rapidly escalating in price and i CANNOT replace a piece like this at ANY price. Frankly, they are like money in the bank which is why I now post so few of my stash of these critters, and accumulate others to save in the bank. As far as any mineral I have ever seen. good Sweet Homes are an appreciable asset to high degree.

Attractive, translucent, color zoned, fluorite crystals, with dark purple cores and lilac edges, measure 5 cm across. In addition, there are euhedral galena and sphalerite crystals on the back side of the specimen. It is a stunning example of classic, purple zoned fluorite from these now defunct mines! NOTE: FROM THE TOM WIESNER COLLECTION, NOT ZINN. just got mixed in
This is one of the finest and most unique fluorite groups I have seen from Berbes. A transparent, lustrous, lilac cube, to 2.5 cm across, exhibits deep purple color zoning in the center of the crystal. This is pretty damned good already! The color and zoning are sharp and rare ! Moreover, associated with the cube is a 3.0 crystal of different habit: cubic highly modified by the octahedron. This crystal also is lustrous, slightly deeper purple, and translucent. Outstanding, in every way!
This UNUSUAL Chinese specimen consists of a thin crust of fluorite upon which grew, nearly-colorless, transparent, lustrous, intergrown crystals of fluorite, to 1.5 cm across. Very pretty and eye catching, liks cubes of ICE !
