A sharp, gemmy, freestanding 2.2-cm fluorite with subtle color gradations and phantoms is perched upon porcelain dolomite crystals, on this superb miniature. The fluorite is complete in back, but covered by a thin druse of quartz. On the front and sides, it is free and clear of any obstruction and perched remarkably upright. The dolomite plate is also free of damage. This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009. It should be remembered as a very distinct style, something different from any we have seen before for the mine or a fluorite combination. NOTE: these exhibit the photographic property of metamerism. They change colors from halogen and professional bulbs (more blue) to indoor fluorescent lighting and even natural sunlight (more green). Examples from both are shown here. The change is startling if you do not expect it, and quite pronounced in the right lighting.
Dramatic purple-cored, cuboctohedral fluorites to 2.6 cm across, are perched on a thin, elongated crystal of dolomite, a floater that is complete all around! This is a well-balanced specimen with contrast that is much more evident and 3dimensional in person. Overall, a very unique association I have not seen before and with two minerals both of high quality. The dolomites have a porcelain-like look to them and the form contrasts to the fluorites vrey nicely. This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009.

This is one of my favorites of the lot, for its graceful elegance. The fluorites are perched n a rather large, slightly curving, twinned dolomite crystal clustre. The gemmy, freestanding fluorites have subtle color gradations and phantoms , and are elegantly perched upon the rim of the porcelain dolomite crystals. The three-dimensionality is MUCH more evident in person, and it has "style" in its flowing form. The fluorite is complete on back faces, and the dolomite plate is also free of damage and complete so the whol epiece taken together is a floater!

Dramatic purple-zoned, cuboctohedral fluorites to 2.5 cm across, are perched on a thin, elongated crystal of dolomite, a floater that is complete all around! Overall, a very unique association I have not seen before and with two minerals both of high quality. The dolomites have a porcelain-like look to them. Purple crystals in this pocket were few and far between, it seems. The Chinese asked a huge premium for them, I am told. I have seen only a few amidst the green-blue colors more common in the pocket.

Dramatic purple-zoned, cuboctohedral fluorites to 1.8 cm across, are perched on a beautiful cluster of 2 crystals of dolomite, a floater that is complete all around!

This specimen features a single, jewel-like, purple-zoned, cuboctohedral fluorite (1.7 cm across) perched on a dramatic plate of dolomite. Except at the periphery, the dolomites are in good shape. Quartz association is a nice bonus! Overall, a very unique association I have not seen before and with two minerals both of high quality. The dolomites have a porcelain-like look to them.

This is a choice, stunning fluorite because of the complex form, and the subtle contrasts and symmetries of the stepped faces and oriented color layers on many edges. The large fluorite cluster, which is absolutely pristine, is perched atop a cluster of sparkling, clear quartzes. It is, overall, a most unlikely assemblage, especially to survive in this condition. There are a few internal fractures, but the surface is unamarred and the interior is otherwise completely transparent. One of the highlights of this collection, it is also one of the larger pieces here.
This is a translucent/transparent vertical stack of superb, razor-sharp, gem crystals growing one atop the other. The piece is even a floater, contacted or partially rehealed on back, and so technically complete all around. The quality, the clarity, is amazing...you do not expect to see it in a piece of this size, and so much at once on one piece. The piece is pristine save only for edge wear on only one edge, of a bottom crystal in the cluster. In person, this has a subtle color that is blue-green-lavender, and frankly seems to change depending on the lighting. In any case, it IS more colorful, and interesting in person, though the photos convey the geometry well.
Dramatic purple-zoned, cuboctohedral fluorites to 3 cm across, are perched on a beautiful cluster of lustrous dolomite and quartz. The dolomites have a porcelain-like look to them. This piece is 3-dimensional and complete, all around. It can be displayed horizontally or vertically as you wish, with equal effect (and would be complete on all sides except the bottom, if horizontal). Purple crystals in this pocket were few and far between, it seems. The Chinese asked a huge premium for them, I am told. I have seen only a few amidst the green-blue colors more common in the pocket.

This specimen is an oddball for the pocket, with a 5-cm-across GEMMY, transparent, complex cuboctohedral crystal just beautifully displayed on a pedestal of more translucent, rough fluorite. The smooth , glass-like surfaces of the dominant crystal are amazing, about the best polished look you can ask for in a fluorite specimen. Minor dolomite and pyrites accentuate the fluorite, giving it a needed accent. This is a very unique, and sparkling, specimen. Purple or lavender-colored crystals in this pocket were few and far between, it seems. The Chinese asked a huge premium for them, I am told.

An exquisite miniature with total transparency to the crystals. In person, you can see that their faces, which are glassy and lustrous, have an unusual slight curvature to them. The color in person is a pale lavender hue. The cluster is 2 cm across, making this a very balanced miniature specimen
This nearly 2-cm crystal has an unusual "crackled" effect on the surface when looked at very closely, or in strong light, but looks smoothfaced from far out. It has a rich purple phantom in the middle. The edges are razor-sharp, very dramatic. The matrix of yellow muscovite is uncommon from this mine and contrasts nicely
Razor-sharp phantom edge lines make these crystals dramatic. Each is about 1.3 cm. The sparkling brown crystals are sharp scheelite octohedra, rare for this locality in association with fluorite.
Absolutely transparent, purple crystals like purple ice cubes, coated with a contrasting carpet of thin, translucent, bladed calcites, , really makes this piece stand out. The edges are razor-sharp. This well-balanced miniature is from a one time pocket, several years ago, with this nice association
A riveting thumbnail specimen, for the stark contrast of the phantoms, and the razor sharp symmetry - blue/purple combos are quite unusual for the mine, too. Actually in person the color is a green-blue shade
