4.4 x 4.4 x 3.3 cm. A classic, old-time combination specimen from Ehrenfriedersdorf, Germany, which is the Type Locality for apatite. A fine cluster of euhedral, lustrous, translucent, pastel-green to gray apatite crystals is capped by a small group of purple fluorite cubes and a couple of cassiterite crystals. Accompanied by an old, handwritten label in German. Highly representative of the species and locale.
5.8 x 4.8 x 4.2 cm. Specimens from the much less well-known Kavalerovo Mining District, near Dal’negorsk, Russia are much rarer than from the much more famous nearby Dal’negorsk mines. A 3.1 cm, very distinctive and diagnostic, blue-green fluorite octahedron is nicely set on and partially enclosed by glassy quartz crystals. The fluorite is nicely translucent and the lightly frosted crystal faces have moderate lustre. The quartz crystals are peppered with fluorite microcrystals and a single, fine, small fluorite octahedron. Specimens of this quality came out in the early 1990s, with none since.
Superb bi-colored fluorites, with wonderful big green octahedrons on lavender-gray fluorite. The green crystals measure to 4.5 cm on edge. 18.5 x 16 x 6.25 cm
A WHOPPER crystal of deep purple, technically a floater since it shows microfaces all across the back and therefore was loose in the pocket for a time. You can see the nice zoning in one of the photos. A tiny bit of edge wear in a couple of spots, VERY minimal for a specimen of this size. 12 x 8.5 x 7 cm
A SIGNIFICANT European fluorite specimen, both for its size and the quality of the crystals, which measure to 3.4 cm along the edge. They are a transparent light blue-grey in hue, and show fine internal phantoms as well. Big French fluorites such as this just do not come along very often! I have seen smaller specimen from the locality, usually without such nice quartz matrix but rather broken off from the matrix. This is , however, one of the better large matrix pieces I have had. I am told that the mine is now defunct, though I am not sure when it closed. 17 x 16 x 6 cm
From perhaps the most exciting new mineral find of the past year -- extremely sharp crystals to 2.3 cm along the edge, nicely balanced on the matrix. The color is a fine balance of purple and green, the ideal from this mine in my opinion. Damage only at periphery with no damage to the display-face crystals. Wonderfully isolated crystals. A fine piece from this super find! 12 x 11 x 3 cm
A solid plate of HUGE crystals, to 4 cm along the edge (!) – sharp and damage-free! The piece has been backlit to show the fine deep purple-and-green color. This one is darker purple-green when in overhead fluorescents but goes a lighter green color with purple highlights when backlit as shown (using just a normal lightbulb, nothing fancy). 13 x 10.5 x 5 cm
Two intergrown, translucent purple cubes from the Elmwood. Contacted on the back and sides but has a nice display face. Mine now closed so stash them now while you can! 6.5 x 4.3 x 4 cm
The largest crystal on this specimen measures almost 4 cm across the edge, and like the other crystals, is as clear as green glass! They are razor-sharp and undamaged, too. Despite the flow of fluorites from China, really superb large plates such as this remain QUITE the exception, are very desirable and stunningly eye-catching. I mean, an 18-cm plate of big, superb, clear crystals? What would this cost from Dalnegorsk. The crystals here, unlike with many specimens, are well-isolated, and stand well out from the matrix. Contacts are limited to the periphery. A sprinkling of small white quartz crystals on the matrix provides a nice contrasting backdrop for the crystals. We have all seen tons of fluorite from china of many varieties, but this recent batch is one of my favorites yet. 18.5 x 11 x 5.2 cm
A superb example of a type of fluorite that has been exceedingly expensive and hard to get in quality specimens. There are three intergrown crystals here of a glowing purple, isolated in the center of a field of contrasting quartz. The largest crystal measures 3.3 cm. These have been amongst the fluorite finds causing the most excitement over the past 2 years, and one can find them on various websites reaching into some really high dollar figures. Occasionally, though, we find a fixerupper at shows and vcan still get them affordably if you put a little work into cleaning. VERY NICE AND VERY INTERESTING MATERIAL - these are worth stashing away as they are so distinct from any other chinese fluorites! 13 x 9.5 x 3 m
I have been harangueing people to pick up good Elmwood pieces while they can with concrete now having been poured down the shaft, ending its run for good. Specimens were scarce at Denver, not surprisingly. This specimen is from a pocket that is unique in my experience. The intergrown crystals here are not only in the very top percentage for clarity - UNUSUALLY light and clear - but there are TWO distinct phantom lines inside each crystal! For someone who has yet to get an Elmwood piece because they have seemed to prosaic, or someone who collects Elmwood and hasn''t seen anything like this, you probably won''t see another one! There is one contact about halfway down on one of the crystals; other than that, they are pristine and sharp. 4 x 4 x 2.8 cm
This is one of the very exceptional pink fluorite plates where a cluster of fine crystals are isolated on matrix with a rim of the contrasting white matrix setting off the crystals in a gorgeous manner. We get very few of that nature even though we keep close tabs on teh mining to select them as they come out. The crystals here have the best deep pink color, and measure to 2 cm on edge. There is NO damage. These fluorites have been a welcome addition to the world of pink fluorite, which up to now has included only super-expensive and rare specimens from Peru and the Alps, largely in very small sizes. 15.5 x 8.5 x 3.7 cm
A STUNNING specimen in every way. It features lustrous, doubly-terminated calcites to over 3 cm that have grown on a cluster of blue-green fluorite that is layered with a coating of bright, sparkly pyrite selectively deposited on various faces of the fluorites! VERY COMPLEX AND INTERSTING associations here, that are better in person...! 12 x 8 x 4.3 cm
This is the biggest and best specimen we saw at Denver from a new find of HUGE, glass-clear purple fluorites! The octahedrons here measure to 5 cm (!). Not only that, but their form is beautiful, like cut glass with ornate modifications (including bevels, epitaxial growth and repetition of the triangular form in stepped growth on the faces). Note that ALL specimens from this find we have seen have heavy contacts around the periphery of the outer crystals (that is the only way to excavate them), and this one has only one or two little cleaves in the main part of the display face that are hard to find. Overall, for the size, we thought it very fine. 17 x 10.5 x 7 cm
Ccluster of crystals in the center measuring 6 cm (with individual crystals to 3 cm along the edge). It is darker matte-purple when in overhead fluorescent lights, but goes more towards a green color with purple highlights when backlit as shown (using just a normal light bulb). 17.5 x 14.5 x 4 cm
