10.9 x 8.9 x 3.4 cm. Uncommon on the market, a specimen of yellow fluorite from Argentina. The crystals are to 1.2 cm, a pretty golden-yellow color with faint internal phantoms with thin purple outlines. The fluorites sit on a field of sparkly chalcedony. From a small private collection of long-collected Argentine minerals built up by a US expatriate down there.
15.9 x 14.5 x 11.2 cm. A large plate of sparkly quartz showcases a 13 cm x 9 cm cluster of fine English fluorites! These wonderfully transparent fluorites measure to 1.5 cm along the edge. Intermixed with them, you can see some gray octahedrons of galena. The Rogerley is a classic English locality that has been re-mined over the past five years, turning out a new generation of fine specimens - highly welcomed by collectors, since English fluorites have a special panache and desirability, and have been just so hard to get. The contrast of deep green crystals with the white quartz makes this large specimen truly special. Highly fluorescent. Fluorites from here on such nice contrasting matrix are hard to obtain.
6.7 x 5.9 x 3.8 cm. This Illinois old-timer is a super-sharp corner of a fluorite crystal that has been completely covered with snowy white calcite. Then, on the calcite grew these micro-crystals of blue-gray celestite - a very unusual Illinois combo specimen! Ex. George Feist Collection.
10.4 x 6.4 x 5.4 cm. Two complex octahedrons of fluorite to 3.5 cm on edge, with thousands of surface microfaces, on a coated, euhedral crystal of quartz. The fluorites are green, with highlights of purple. Rare material from an abandoned Soviet-era military-run tungsten mine!
6.5 x 4.9 x 3.9 cm. A cluster of fluorite crystals from earlier finds at the Okarusu, not the recent ones. The crystals measure to over 2 cm on edge. They have a nice transparent teal color, with purple highlights. A couple of small contacts, but overall in very good shape. From the well-known California collection of Charles Hansen.
17.0 x 15.0 x 7.4 cm. A BIG plate of transparent green fluorite crystals, from China. These crystals are in fine shape, some with natural corner and edge stepped modifications. The crystals measure to 2.5 cm on edge. FLUORESCENT. Beautiful, big and green!
5.7 x 4.9 x 2.4 cm. Incredibly complex, compound fluorite crystals composed of modifications of the cubic form, surrounded by bursts of milky calcite. The fluorites, with pretty purple blushes deep in their interiors, measure to 1.7 cm.
10.4 x 8.4 x 4.9 cm. This was a very limited find of a unique translucent, honey-colored fluorite that formed a thick crust, with the surface consisting of thousands of sparkling micro-faces. This is a large specimen from the find.
27.8 x 14.4 x 6.5 cm. This is a monster specimen of the famous "water-clear" fluorite mined in the early 1980s at Dalnegorsk. The surface of the specimen is completely covered by hundreds of these clear fluorite cubes (maybe 200?). They are accented by little bursts of tan-colored quartz. The fluorites measure to 1.5 cm, though most are smaller. THERE IS ALMOST ZERO DAMAGE! These clear cubes have stopped coming out, and it is too bad, because they are amongst the most pristine fluorites that have ever been found. Have you ever seen hundreds of them together on one specimen? This is just an astonishing piece for its size and richness. Ex. Fersman Museum of Moscow back in the early 90s, probably 93-95.
9.5 x 7.5 x 7.0 cm. A LARGE, 5.3 cm, translucent, lightly frosted, green and pink fluorite octahedron jaunitly perched atop matrix of muscovite and albite from Chumar Bakhoor, Pakistan. This is classic and excellent material from this famous pegmatite locality. The fluorite is complete all-around, but is contacted on the back, which is out of sight. Ex. Chris Korpi Collection.
9.0 x 7.2 x 5.2 cm. Two very glassy, translucent, intergrown, chocolate-brown fluroite cubes form an EXCELLENT and showy specimen from the famous White Rock Quarry at Clay Center, Ohio. The sharp righthand crystal is 4.5 cm on both edges, has EXTREMELY gemmy corners and is nicely accented by a DT calcite crystal cluster on the front. This is CLASSIC material from this famous locality. SUPERB fluorescence and phosphorescence. Ex. George Elling collection.
9.0 x 5.6 x 3.6 cm. A strange quartz specimen that seems to have beta-quartz shaped smoky crystals, on matrix with little green fluorites. These smokies are REALLY dark, opaque, and strikingly sharp. The contrast on the green is interesting, too. Never seen one like it, myself. Ex. Richard Hauck Collection.
14.4 x 10.8 x 8.6 cm. Dark gray limestone with a layer of banded, massive, quartz, is host to large lustrous and translucent crystals of fluorite, to 4 cm across. Individual crystals exhibit both a rich emerald green at the core and gemmy purple even in daylight (from the slight UV rays they catch and fluoresce to). In addition, the crystals clearly show off penetration twinning. This specimen features some of the largest fluorite crystals yet found in the recent mining at the Rogerley mine, and come from the last pocket found in the digging season of 2007.
12.9 x 10.3 x 5.4 cm. This is a sculpturally dramatic plate of penetration-twinned crystals of lustrous and translucent fluorite, to 4 cm across. The core of the crystals is a rich emerald green color while the crystal edges are a rich gemmy purple even in daylight (from the slight UV rays they catch and fluoresce to). Very showy piece, though it has no matrix, for the overall form! There is very minor edge wear only, nothing seriously detracting, but it is there. This specimen features some of the largest fluorite crystals yet found in the recent mining at the Rogerley mine, and come from the last pocket found in the digging season of 2007.
17.4 x 12.4 x 11.5 cm. A matrix of banded white quartz hosts this very large cluster of twinned, lustrous and translucent fluorite crystals to 3 cm across. Rarely do you get such a LARGE specimen with no damage of note and such good coverage, in fact 360-degrees around?! The core of the crystals is a rich emerald green while the gemmy crystal edges are a rich purple even in daylight (from the slight UV rays they catch and fluoresce to). The total visual impact/effect of this large specimen is really amazing. Historically, there just is not much available of this size and quality.
