11.0 x 8.7 x 7.5 cm. Glassy, pearlescent baryte spear-points in en echelon bundles are richly and attractively mounded on the bit of fluorite matrix on this classic and aesthetic cabinet specimen from the Annabel Lee Mine of Southern Illinois. An excellent and highly representative large example of the species and noted locale. Always these were rare and highly treasured and valued, by the local miners.
9.9 x 9.8 x 4.3 cm. This superb specimen consists of three Fluorite spheres (to 1.3 cm) and a 2-cm scalenohedron of Calcite, all perched on literally ropelike stalactites of translucent quartz crystals. Many of the quartz crystals actually comprise very attractive and visually delicate stalactites within the Chalcedony/basalt vug.
14.0 x 10.6 x 4.6 cm. This is a very important locality specimen. Open for only ten years in the mid-1900s, the Deardorff Mine is not one of the household names when it comes to Illinois fluorite. However, it had a unique association of fluorite and quartz which remains one of the most sought-after Illinois classics to this day. For whatever reasons, quartz is rare in the other nearby mines, particularly in association with good fluorite. This association is both dramatic and classic for the mine - if in somewhat larger size than we usually see. The fluorite cubes, to 3.75 cm across, exhibit good luster and near-transparency along with a fine pastel- blue color. When viewed from the side there is a hint of color zoning with purple overtones. The lavender fluorescence adds to the beauty of this specimen. I have purposefully chosen to leave the piece un-cleaned with modern technology which could remove the iron pocket-staining and make the piece look too modern and sparkly. Ex. Dr. Edward David Collection.
Translucent crystals to 1.5 cm on edge, with a pretty light purple blush along the edges. There are corner cleaves, but this is a nice specimen nonetheless. 8.2 x 5.8 x 1.1 cm
Transparent-to-translucent crystals to 0.8 cm cover the face of this undulating matrix. A relatively large specimen of really nice crystals! 10.9 x 8.0 x 6.5 cm
I bought most of the top specimens from this small 1-time, unprecedented pocket. This specimen features lustrous, black 1-cm size tedrahedrite crystals associated with tufted ,bright green malachite,an occasional frosted lilac fluorite crystal and a few mm size light pink rhodo rhombs. This colorful combination sits on white quartz vein matrix. For the pocket, it is quite rich in good isolated malachite balls. 5.8 x 3.2 x 2.8 cm
An excellent, doubly-terminated, lustrous and pristine ferberite crystal with fluorite from the famous Yaogangxian Mine of China. 5.6 x 0.9 x 0.7 cm
10 x 8.4 x 4.8 cm. This is a very appealing rhodochrosite, unusual in its combination with both fluorite and tetrahedrite. The tetrahedrite occurs as sharp, metallic crystals and may actually be overtopping large bornite crystals, it seems. The piece is very nearly pristine, and no restoration or repairs whatsoever. The large central crystal is 5 cm across, and it is draped with fluorite and smaller rhodochrosite crystals. The lustre is high, and the color saturation is uniform. This is an excellent piece overall, and has a huge amount of color, considering what else I have seen on the market these days. The fluorites are sparkling and a nice lavender hue, in person. I acquired this piece for my private collection, of fine large Sweet Home rhodochrosite specimens, in 2006 at the Munich show. Ex. Rob Lavinsky Collection.
5.5 x 4 x 3 cm. This specimen is to me one of the most elegant fluorites I have ever handled. It has so much contrast: of the sharp cubic form so unlikely to be perched atop curving barytes; of the stunning purple color set against a chalky white pedestal; and of the clarity and gemminess contrasted to the opaque barytes on which this crystal sits. The piece is a very large miniature at 5.5 cm. Perhaps more properly it is a small, small cabinet piece. The crystal is 2.2 cm by 2 cm on front, and extends at most 2 cm deep to the rear. The specimen was perhaps for 2 decades in the miniatures collection of Dr. Steve Smale, known for his finicky taste for pure perfection when at all possible. He exchanged it long ago to another local collector in the Bay Area, Steve Smith, from whom I have recently obtained it. Photo by Joe Budd.
10.1 x 7.8 x 4.4 cm. An extremely aesthetic and unique cabinet specimen of a gem, yellow fluorite corner enclosed in lustrous, colorless calcite rhombs from the Minerva #1 Mine of Illinois. The water-clear, rich yellow fluorite corner has hints of purple as an interesting accent. Outstanding material from the Duncan Elliott Collection.
7.5 x 5.3 x 3.8 cm. An aesthetic fluorite cluster from the Elmwood Mine. Lustrous, translucent, pretty purple cubes to 3.3 x 3.3 cm have deeper purple edges and colorless interiors. The striking, stepped-growth faces really add character to this excellent piece, which is on sphalerite matrix. Classic material from this noted locale. Ex. Consie Prince Collection.
A beautiful, mostly water-clear, floater cluster of pastel sea-green interpenetrating fluorite crystals from the famous Yaogangxian Mine of China. Two slightly dinged crystal corners are totally out of sight from most viewing angles. 2.5 x 2.1 x 2.0 cm
Crust of two generations of lustrous and translucent octahedral fluorite crystals on massive fluorite. Sea-green fluorite octahedrons were overgrown by the smaller golden to yellow octahedrons. 11.8 x 7.0 x 6.4 cm
A VERY DRAMATIC and SHOWY specimen. A lustrous, 4.0 cm long amethystine quartz crystal rises centrally above a beautiful 2.5 cm quartz pseudomorph after fluorite crystal. Some of the smaller, lustrous amethystine quartz crystals on the matrix are iron stained. Quartz after fluorite pseudos are rare. Very trivial edge wear on the large crystal tip. 8.5 x 8.0 x 4.0 cm
10.5 x 8.8 x 3.8 cm. Discrete, translucent, "Blanchard-blue" to purple fluorite cubes are aesthetically scattered on the quartz matrix of this fine cabinet specimen from the Blanchard Mine of New Mexico. The striking, dominating cube is 3.0 cm and the cubes have nice purple edges. This is uncommonly fine Blanchard material, as most fluorite specimens are intergrown clusters of crystals. Contemporary classic material.
