These specimens of large, bright green fluorite octahedrons on an earlier generation of purple-gray fluorite represented one of the most exciting finds of the past year. But they disappeared soon after they arrived – no more have come out and there is no indication that they ever will. This is a small cab, of very high quality. The crystals are sharp and very transparent for this find, and sit nicely up on the darker fluorite. There is a rough spot on a corner of one of the crystals, which might be a rehealed area or just a very complex termination – it is not clear which – but it certainly does not detract, as this is the large lower crystal that sits at the bottom and the best crystals are more prominent, in a row along the top. Damage is limited to the normal stuff around the periphery (the large crystal at bottom is not complete on the back as that is where the specimen was removed from matrix). The large crystal measures over 5 cm, the ones along the top around 3.5 cm. 8.8 x 6.3 x 4.6 cm
2.3 x 1.6 x 1.5 cm. This is a fine combination piece consisting of gemmy clear-to-purple Fluorite cubes (partially coated with drusy Quartz for accent) arranged enechelon along a pair of gemmy and highly lustrous Scheelite crystals. Very distinctive, not only for the aesthetics but for the location, as well. Ex. Marilyn Dodge Collection.
This is such a good combination piece. The Fluorite is a partial and very sharp octahedron with flashes of green and pink, which bears an uncanny resemblance to the famous Peruvian Fluorites. Place this on two sharp cream colored Baveno Twin Feldpars, and you have an amazing thumbnail. 2.1 x 1.5 x 1.5 cm
Botryoidal fluorite is relatively uncommon, worldwide, known from a very few localities of which this is most famous. This particular specimen is translucent, purple, and fluoresces a lovely green color. The largest sphere is 1 cm across. Complete on both sides, and quite elegant as these oldtimers go! 7.1 x 5 x 2.4 cm
This is an aesthetic specimen of botryoidal, purple fluorite from one of the few localities in the world that produce these unusual fluorites. The largest sphere is 1.5 cm across. Complete on both sides, and quite elegant as these oldtimers go! 6 x 3.2 x 2.6 cm
I have never seen a piece quite like this...This is a fascinating mineralogical oddity. The form of the white crystal is obviously that of celestine, which has been altered. In fact, on the underside, are some very light blue primary (original) celestine crystals along with minor dark purple fluorite.The celestite had evidently grown upon the fluorite, and some remains attached. Even for the pseudomorph collectors, this one is definitely different. NOTE: NOT ZINN . FROM THE TOM WIESNER FLUORITE COLLECTION (a major Illinois stash), part of which i got at the same time. 5.3 x 5.8 x 4.8 cm
This fine, sky blue, transparent, fluorite specimen has deep purple centers, which give it an ethereal quality because they look phantomlike tucked back behind so much blue zoning. This is a great display piece of an increasingly rare American classic! The largest crystal measures 6 cm across. It also fluoresces a deep, rich purple color. The label indicates that this piece was mined in 1981. NOTE: NOT ZINN . FROM THE TOM WIESNER FLUORITE COLLECTION (a major Illinois stash), part of which i got at the same time 12.5 x 12.5 x 6 cm
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 6.2 x 5.1 x 4.9 cm
A remarkable piece for the location, featuring a fat, unusually large octohedral fluorite of classic grape juice color, perched on sparkling matrix of drusy quartz. I have never seen such a large, freestanding crystal from this locality! This is a major US fluorite, for intrinsic quality aside from the locality value itself 6 x 4.7 x 3.4 cm
This mine is noted for fine calcite crystals on fluorite. However this is an especially fine cluster of slightly radiating crystals of amber-colored, lustrous, bladed barite which is perched on purple fluorite. In turn, the fluorite is studded with tiny calcite crystals. The longest barite is 3 cm in length. There is one slight (natural?) divot in one barite crystal that is hard to notice but nevertheless is there; otherwise the group is in good shape. The largest of the intergrown fluorite crystal is 1.5 cm across. A label notes that it was collected in 1984. 6.9 x 6.3 x 5.9 cm
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! 9.3 x 7.1 x 4.9 cm
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. 8 x 5.8 x 3.8 cm
6.4 x 5.1 x 4.6 cm. A very strange Illinois specimen that is evidently an old specimen, said to have come from surface workings near the mine and from a well-known Illinois collection. Deep purple cubes, some possibly pseudomorphed (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. Ex. Tom Wiesner Collection. NOTE: according to Ross Lillie, this strange 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 wasn't considered important in 1959 so that’s probably why there was no record.
Bright, lustrous, black, sphalerite crystals to 1.5 cm across, form the matrix for a magnificent, translucent, deep purple fluorite cube (2 inches or 5 cm across!). The equant fluorite even exhibits slight color zoning at the crystal’s edges for added visual impact. I know this is "just" fluorite and sphalerite, once common from the mine, but try to find a better one for the price today and you will be hard pressed. This specimen is superb in its aesthetics and even when the mine was producing would have been a top-notch specimen 11.1 x 7.6 x 6.5 cm
A frosted, light emerald-green fluorite crystal combined with a gemmmy, shimmering and mirrorlike muscovite crystal, form a V-shape which frames a well developed , colorless and transparent quartz crystal. VERY DRAMATIC AND 3-DIMENSIONAL! In addition, there is a minor schorl peeking out from behind the muscovite. Complete on the front and sides, contacted diagonally along the back face of the quartz and fluorite. The fluorite and muscovite crystals each measure 3 cm and the quartz is 6 cm tall. The combination of mineral species and aesthetics really stand out in this specimen! 6 x 5.1 x 2.5 cm
