These fluorite crystals (to over 1 cm) are so gemmy-clear that you see right through them! And inside them are very sharp purple PHANTOM crystals that you see inside the glassy exterior. 8.0 x 5.7 x 4.2cm
A EXCELLENT fluorite thumbnail of two, intergrown, near-transparent, lustrous octohedrons of the VERY BEST rose-pink color from the Argentiere Glacier at Chamonix, France. This is CLASSIC and very desirable material from a sought-after locality. A trivial wilbur on one termination certainly does not detract from this beautiful piece. 1.9 x 1.3 x 1.1 cm
A very showy and rich specimen of botryoidal, yellow, smithsonite on massive fluorite from the famous Sheshodonnell East Mine, Carron, The Burren, County Clare, Ireland. A bit of periphery damage is insignificant as it displays so nicely and colorfully. This fine piece was recently collected from the dumps produced by old workings 5.4 x 4.0 x 4.0 cm
A sizeable combo specimen of gemmy purple fluorite crystals to over 2 cm with equally gemmy quartz crystals, some of them with an unusual flattened form, wiith chlorite inclusions that add a pretty moss-green accent. The fluorites are beautifully set off against the quartz cluster, and this cluster is complete all the way around - with attachment only on the bottom. 11.9 x 9.7 x 5.6cm
Look at these perfect pastel-green balls of fluorite, nestled like eggs on a plate of contrasting light-gray quartz crystals! A large and dramatic specimen! The fluorites measure to 1.7 cm across. These came out in one find of about 4 years ago anow and are unobtainable 12.2 x 10.0 x 3.9cm
A LARGE plate of purple fluorite, from Weardale. It is very tough to get large plates of English fluorite of this size and richness today! And, these crystals are in superb condition - very few dings, and those pretty minor. The crystals measure to over 5 cm on edge! They have unusual white inclusions that look like clouds inside, and other parts are very gemmy. In places, there is a coating of microcrystals of what appears to be quartz and hematite. As with all English fluorites, this specimen is HIGHLY fluorescent! 15.3 x 14.6 x 4.8cm
A BIG, thin, slightly convex matrix completely covered with beautiful pink fluorite crystals! We had not been able to get decent specimens for some time, until we met up with our contact at the Tucson show. Until these pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite, and the cost of a specimen such as this was (and still is) astronomical from those localities. Occasionally, such as with this particular piece, you get the wonderful clarity of an Alpine piece as well. These octahedrons measure up to 1.5 cm. 20.9 x 14.4 x 5.1cm
GEM-LIKE, deep purple cubes of fluorite, razor-sharp and pristine, isolated on a matrix of dark muscovite. The fluorites measure to 1 centimeter, and are wonderfully isolated on the contrasting matrix. 7.9 x 6.1 x 1.8cm
I was sorry to see these dramatically-zoned fluorites disappear from the market over the past couple of years. The phantoms inside often, as in this case, have a growth of quartz microcrystals that sharply demarcates their faces – creating superb examples of the phantom phenomenon. This crystal is just superb in terms of its phantom, its transparency, its fine condition, and the way it sits on the matrix. 4.5 x 3.9 x 2.3 cm
An AESTHETIC and beautiful stacked cluster of lustrous and gemmy, interpenetrating, sea-green fluorite cubes from Weardale, England. The right side of the face on the top right cube is contacted, but is out of sight and the couple of trivial edge bruises are certainly not detracting. SUPER PURPLE fluorescence, as you would expect. You can even see the purple fluorescence in the photos. 2.9 x 2.8 x 2.3 cm
This fluorite specimen, mined in 1991 at the Minerva Mine, shows some gorgeous zoning! The larger crystals have yellow interiors with purple outlines. The smaller ones have purple interiors, with a stripe of teal-blue in the clear part outside the purple core! Somehow, these crystals, though in the same cluster, formed at different times when the solution in the pocket varied, leading to the differences in hues as the crystals grew. Note the little calcite decorating the crystal faces as well! 9.1 x 7.8 x 7.5cm
A jewel-like, water-clear crystal of fluorite on matrix from Dalnegorsk. The crystal does have a natural contact in one place, but it does not detract. Can be trimmed in an instant into a stunning thumbnail if you wish! 4.9 x 2.8 x 2.4cm
We saw no more of these at the Tucson show, and wonder if there are any more coming out? At any rate, they were one of the most sensational finds of last year - distinct, euhedral crystals of purple fluorite floating clearly inside of fine, terminated quartz crystals! It is interesting to look inside the quartz and see air-filled spaces where fluorites once were that we later dissolved by the solution, then covered up again by quartz. There must be 10 or 12 little fluorite crystals in this quartz crystal - better in person, hard to photograph! 7.1 x 1.8 x 1.2cm
This is a large plate of transparent, light-purple fluorite crystals, very sharp and lustrous, many of them with a perfect phantom inside, of a milky white, in a sharp cubic shape! The solution in the pocket changed during the growth of these crystals to result in the ealier milky crystals being wrapped in the more traditional (for Shangbao) transparent fluorite. These crystals measure to a little over one centimeter across the edge. 16.5 x 14.5 x 6.3cm
This is the second of two large plates of fine pink fluorite we got from our contact in Tucson, after an interval of not being able to get any decent ones. The other sold in the auction for $815 after fierce bidding last week. This big specimen is completely covered with beautiful pink fluorite crystals! We had not been able to get decent specimens for some time, until this meeting in Tucson; they had cherry-picked some pieces for us from the latest mine production. Until these pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite, and the cost of a specimen such as this was (and still is) astronomical from those localities. Occasionally, such as with this particular piece, you get the wonderful clarity of an Alpine piece as well. These octahedrons measure up to 2 cm. 3.7 x 2.5 x 2.2cm
