13.1 x 6.7 x 6.3 cm. This is from a new pocket found at the end of 2008. It is a fine piece featuring subtly phantomed, green-blue fluorite perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The fluorite is pristine over the length of the display face and the crystals measure to 2 cm. 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.
11.6 x 6.8 x 6.4 cm. This is from a new pocket found at the end of 2008. It is a fine piece featuring cuboctahedral purple crystals phantomed with deep purple cores. Only a handful of specimens in this pocket were purple. The fluorite is perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The larger fluorite, 3.4 cm across, is pristine and the smaller one is nearly so. The dolomite on the display face has excellent lustre, and is complete except for only a few peripheral crystals.
13.8 x 10.4 x 5.2 cm. This is from a new pocket found at the end of 2008. It is a fine piece featuring subtly phantomed, green-blue fluorite perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The fluorite is pristine over the length of the display face and the crystals measure to 4 cm. They are extremely 3-dimensional. The dolomite plate is complete on the display face. 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.
11.4 x 8.3 x 8.1 cm. This fine piece features a pristine, 3.8-cm-across fluorite with intense green-purple zoning. No subtle phantom here. The crystal is one of the best and biggest of this style. It is pristine, complete, and totally translucent. The dolomite next to it is 6 cm. It is perched on both quartz and porcelain-like dolomite, making for a great contrast. This is from a new pocket found at the end of 2008. 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.
9.5 x 7.4 x 4.9 cm. This fine piece features a pristine, 3.4-cm-across fluorite with complicated, subtly layered, green-purple zoning. The crystal is pristine, complete, and totally translucent. The dolomite holding it up is very dramatic and 3-dimensional, complementing the fluorite by its very different shape and color. This is from a new pocket found at the end of 2008. 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.
14.6 x 11.8 x 7.5 cm. This bizarre specimen is from a very small mine that I am told played out quickly and produced few specimens. This piece, despite its size, is remarkably pristine. It is also a floater, complete all around, and even on the backside (where it broke from the pocket, and some later crystallization healed the wound). The piece is a vivid green color and it glows when backlit. In stronger lighting, it is entirely transparent. The whole display face, and all those outstanding gemmy cubes at the major octahedral points, is nearly pristine. Mined in 2005.
12.3 x 12.0 x 7.2 cm. This fine piece features a pristine, 8-cm-across dolomite cluster splaying from a cluster of gemmy, lavender-colored fluorite of very unusual form and color for this mine. The fluorite is very unusual...only a few of this style were recovered. It is pristine, complete on the display face although contacted in back, and totally translucent. The dolomite is a very good size and has a sparkle to it; a sheen of pearlescence, which is appealing. This is from a new pocket found at the end of 2008.
9.7 x 7.3 x 5.7 cm. This fine piece features a pristine, 3-cm-across fluorite with complicated, subtly layered, green-purple zoning. The crystals atop are both freestanding, pristine, complete, and totally translucent. The dolomite underneath it is very dramatic and 3-dimensional, complementing the fluorite by its very different shape and color. It is also a rather large dolomite crystal, too. A sprinkling of small, green-blue fluorites run downs its saddleback, for accent. This is from a new pocket found at the end of 2008.
10.3 x 7.4 x 5.3 cm. A large plate of sheer color, this gorgeous and unusually rich example from the pocket has deep, rich color. In halogens it goes blue and in inside fluorescent lighting it goes a rich sea-foam green with blue/purple cores. The whole nest of fat fluorites sits on a massive, large dolomite crystal. This is from a new pocket found at the end of 2008.
9.9 x 6.5 x 4.2 cm. This is a fine small cabinet featuring a balloon-like 4 cm fluorite perched snugly atop an elongated dolomite crystal. The fluorite is riveting in its complexity on the surface and internally, hidden within simplicity of overall form. It is transparent despite its thickness, and glows like a jewel atop the dolomite matrix. This is from a new pocket found at the end of 2008.
8.5 x 7.7 x 4.2 cm. This beautiful and unusually rich example from the pocket has deep, rich color. In halogens it goes blue and in inside fluorescent lighting it goes a rich sea-foam green with blue/purple cores. The whole nest of fat fluorites sits on a massive, large dolomite crystal underneath, and the fluorite coating is complete all around. In person, it is much more 3-dimensional than it appears here. This is from a new pocket found at the end of 2008.
9.2 x 6.3 x 4.7 cm. A large, 3-cm crystal sits in a cluster with smaller fluorites, on a bed of small dolomite crystals, all on massive dolomite. This piece has unusually rich sea-foam green-blue color and really for color impact is among the best here, though its phantoms are minimal. This is from a new pocket found at the end of 2008. 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.
7.9 x 6.4 x 6.0 cm. Sharp, gemmy, freestanding fluorites to 1.75 cm, with subtle color gradations and phantoms, are perched upon porcelain dolomite crystals, on this fine small cabinet. The fluorites are complete-all-around and perched on beautiful, contrasting dolomite crystals. A quartz shooting up next to one fluorite is a welcome accent. This specimen has crystals with particularly deeply colored purple cores in sea-foam green cushions of later fluorite around them. It is more 3-dimensional and colorful in person. This is from a new pocket found at the end of 2008.
6.1 x 5.4 x 4.3 cm. This balloon-like, fat crystal of fluorite measures 4 cm across. It has a deep purple core and blue-green zones around it, leading to very complex, stepped faces on the surface. This is one of the larger cuboctahedral crystals in the find, and of a very high quality because of the color saturation, size, and the complete-all-around aesthetics. The fluorite is perched on, impaled on, a single dolomite crystal and stands upright as shown. The dolomite is complete all around and in fact, even on the bottom - so the whole combination is a floater. This is from a new pocket found at the end of 2008.
6.8 x 5.7 x 2.5 cm. A sharp, gemmy, freestanding 2.2-cm fluorite with subtle color gradations and phantoms is perched upon porcelain dolomite crystals, on this fine 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. 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.
