4.7 x 3.8 x 2.4 cm. Water-clear, extremely glassy, purple fluorite cubes with outstanding interior zoning from the fluorite mines of Berbes, Spain. The cubes reach 2.3 cm on this superb cluster.
8.0 x 5.6 x 3.7 cm. A superb cluster of glassy, transparent, emerald-green fluorite cubes with fabulous purple color zoning from the famous Okorusu Mine of Namibia. The cubes reach 3.6 cm on this beauty, which is seriously accented with a pristine, tan fluorite crystal. The two, opposing, large fluorite cubes are striking.
11.2 x 4.9 x 4.9 cm. This is an elongated knob completely covered with sharp glossy crystals of fluorite, from recent finds at the Okorusu. If you peer inside these crystals, you will see that they are beautifully zoned, with a violet-colored center, and then a thin band of teal sandwiched by clear fluorite.
16.8 x 12.3 x 7.8 cm. As with the pink fluorites from the same locality, until these creedites were discovered, good crystallized specimens were exceedingly rare any locality. Then, last year, the mining was finished, apparently for good. This is a big specimen covered with unusually thick, sturdy crystals. It is also distinguished by having intergrown crystals of purple/green fluorite, which a small number of specimens did, adding a lot to the overall aesthetics.
5.8 x 5.4 x 5.4 cm. From a recent find where the fluorites had an unusual combination of the teal blue very familiar from some of the Blanchard shafts and the purple usually found in separate shafts. This one has mostly purple, with just a bit of the teal. This specimen has razor-sharp, very pretty crystals.
16.8 x 12.2 x 9.5 cm. This find really shocked the mineral collecting world, because botryoidal fluorites are rare, and here you had not only purple ones (which had rarely been seen before), but sometimes in huge sizes. This specimen weighs 5.7 pounds. These translucent specimens glow a luscious purple under good light. Those flattish sides are NOT damage or cleaves, they are natural deformations.
14.9 x 12.9 x 3.2 cm. Until these pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite. Now, the mining here is finished. The octahedra on this large plate measure up to 1.8 cm on edge.
9.6 x 6.9 x 3.4 cm. A plate of lustrous golden-yellow crystals of fluorite from Spain. The crystals are wonderfully transparent.
12.3 x 6.9 x 2.4 cm. Until these pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite, and the cost of a specimen such as this was (and still is) astronomical from those localities. Occasionally, such as with this particular piece, you get fine clarity approaching Alpine pieces. These octahedrons measure up to 1.5 cm on edge.
9.5 x 7.5 x 5.6 cm. Shimmering discs of snow-white baryte have grown on a field of the gemmy golden-yellow fluorites that are familiar from this locality.
20.9 x 11.9 x 10.9 cm. A huge specimen of super-transparent, lustrous crystals of golden-yellow fluorite from Spain. This is the side of a meandering pocket complete lined with crystals.
8.3 x 8.2 x 7.4 cm. This is a huge crystal of fluorite from the Elmwood Mine. It is actually colorless to a very slight cream color in the center - the purple is on the outer rind. There is a peppering of very tiny sphalerites on the surface as well. You can see that the corners are transparent - a phenomenon characteristic of the Elmwood (sometimes, the fluorites actually etch away, leaving only these gemmy corners). There are complex stepped sub-faces all over the sides of this big crystal. The front of the crystal is complete, with only a very few tiny contacts; the back is the matrix attachment/cleave from removal - there is some sphalerite attached on the back. From the old dealer stock of Consie Prince of Houston Texas.
11.0 x 7.0 x 6.3 cm. A superb, 4.8 cm, translucent, sea-green, rounded fluorite octahedron aesthetically perched on quartz matrix from the Ed David Collection. The internal refractions within the fluorite are beautiful and there is even a touch of rose quartz (close-up) to the left of the fluorite. This outstanding cabinet piece is from the less well-known Kavalerovo Mining District, near Dal’negorsk, Russia. This is a much rarer locale for specimens than the nearby Dal’negorsk mines.
11.0 x 7.3 x 2.2 cm. A spectacular and rare cabinet combination specimen from the Blanchard Mine of New Mexico. Electric-blue linarite richly covers the quartz matrix plate and is accompanied by rarely seen together translucent, purple fluorite cubes to 6 mm. Material of this richness and rarity came out in the 1960s or 1970s. Ex. Mullane Collection.
7.8 x 5.2 x 3.7 cm. A beautiful 3.5-cm-across botryoidal fluorite perched like a fried egg as we fondly call them on lustrous quartz crystals. Modern classics from India, these were more abundant a few years ago and not around as much now. Ex. Charlie Key.
