8.1 x 6.0 x 4.2 cm. A 1.6 x 1.4 x 1.3 cm, light "Blanchard-blue" fluorite cube beautifully set on vuggy quartz crystal matrix from the Blanchard Mine of New Mexico. The isolation of the single, lustrous, translucent and lightly frosted fluorite on this large of matrix is uncommon and exceptional. A specimen of this size usually has multiple fluorite crystals. The scattering of smaller, "ice-blue" fluorite cubes is a very nice accent. Contemporary classic material.
6.4 x 5.2 x 1.9 cm. A showy and excellent plate richly covered with very glassy, transparent, golden-yellow fluorite cubes to 1.3 cm from recent finds at the Moscona Mine, Spain. This excellent, highly representative piece is very nearly pristine.
11.6 x 7.9 x 2.2 cm. Until these lustrous, translucent, pink fluorites were discovered in Mexico, Peru and the Alps were the only sources for pink fluorite. These octahedrons measure up to 1.9 cm, and have fine deep pink color against the beautifully contrasting white matrix. An excellent, sculptural cabinet plate.
7.4 x 6.8 x 4.5 cm. A fine cluster of intergrown, translucent, "Blanchard-blue" fluorite cubes set on colorless fluorite from the Blanchard Mine of New Mexico. The cubes have beautiful blue color and reach 1.1 cm. Contemporary classic material.
3.4 x 2.6 x 1.5 cm. A classic cluster of two intergrown, gemmy and lustrous, rose-pink fluorite octahedrons from a renowned Swiss locale - St. Gotthard. The large crystal is 2.5 cm. The terminations are particularly gemmy and the crystal faces are lightly frosted. Ex. Jamie Bird Collection.
4.2 x 3.0 x 2.4 cm. A showy specimen of totally gemmy, bi-colored, light sea-green and colorless, cuboctahedral fluorite crystals. Some crystals have distinct, stepped-growth faces and the piece is nicely accented by a bit of sphalerite at the base. Many of the cuboctahedral crystal faces are lightly frosted, but some are water-clear, giving a neat television-like view into the crystal interior. From the recent find at Naica.
7.8 x 7.0 x 5.2 cm. Fluorite specimens from the Kentucky portion of the famed Illinois-Kentucky Fluorspar District were seldom preserved and hence, are seldom available. This is a showy, 3-dimensional cluster of intergrown, translucent, light gray fluorite cubes, with a hint of interior yellow, grading upward to a very pleasing, light purple. The darker purple edges are particulary striking and add great beauty. The large, purple cube on the crest is 2.5 cm. Ex. Mullane Collection.
15.4 x 7.2 x 6.4 cm. An excellent, two-sided cabinet specimen of translucent, green fluorite octahedrons. The large, dominating octahedron is 6.0 cm. These fluorites came out in modest numbers for only a short time, and have essentially disappeared form the market (see recent Min. Record China issue for more on these). It is quite hard now to find nice-looking, undamaged crystals, on or off matrix, and the Chinese dealers value them highly.
11.8 x 6.4 x 5.8 cm. Ice-like, water-clear, light green fluorite cubes form a very showy and excellent, 3-dimensional, mounded cabinet specimen from recent finds at the Xianghualing Mine of Hunan Province. The largest cube is 3.5 cm and all of the crystals have interesting, modified, serrated edges. This superb, two-sided piece is pristine.
2.7 x 2.2 x 1.5 cm. A rare, excellent and showy thumbnail combination specimen from the Tong Wha (Tae Hwa) Mine of South Korea. A cluster of water-clear, "invisible" fluorite cubes is set in the middle of a triangular matrix of lustrous muscovite books, with nicely framing, off-white dolomite rhombs. This is surely older and very uncommon material from the well-known locale. Ex. Carl Davis Collection.
4.0 x 3.8 x 2.9 cm. A very aesthetic, classic fluorite on sphalerite specimen from the Elmwood Mine. A gorgeous, 2.7 x 2.4 cm fluorite cube is perched on iridescent sphalerite. The translucent, highly lustrous cube has super purple color, scintillating, stepped-growth faces and beautiful, darker purple, color-zoned edges. This is classic, color, form and habit from Elmwood. These were found in one pocket, long ago.
4.7 x 3.9 x 3.8 cm. A beautiful cluster of lustrous, transparent, purple fluorite cubes with a yellow core from the famous mid-1990s finds at the Minerva #1 Mine of Southern Illinois. These are certainly one of the most sought-after fluorite varietals from the very well-known and now, essentially extinct, Southern Illinois Fluorite District. The fluorite cubes are in super shape, with only trivial edge-wear. Ex. Jaime Bird Collection.
2.7 x 2.7 x 2.7 cm. A gorgeous, 1.9 x 1.9 cm fluorite cube is nicely set on a carpet of sparkly, gemmy baryte microcrystals. The translucent, highly lustrous, cube has super purple color, scintillating, stepped-growth faces and beautiful, darker purple, color-zoned edges. A smaller fluorite is perched, like a cap, atop the large cube, on another carpet of sparkly baryte crystals. This is classic, color, form and habit from Elmwood. This is a totally pristine, 360 degree specimen. Ex. Jaime Bird Collection.
An interesting, starkly geometrical plate composed of quartz that has completely cast over and replaced fluorite . The quartz varies from 8 mm or so to several cm in thickness. The backside (negative cast) of the specimen is completely covered with sparkling sphalerite in a dense coating of small crystals, while the front has an ENTIRELY different sulfide deposition consisting of isolated galena crystals and isolated sphalerite crystals. Why the front and back should be so different, I hav eno idea. Anyways, though, it is darned neat to look at and is certainly an oldtimer! Ex. Scott Williams dealer stock, too. 14 x 13.1 x 2.5 cm
8.7 x 7.4 x 5.7 cm. The beautiful and distinctive, sharp, light green, fluorite octahedrons from the Homestake Mine of Arizona were in high demand at the 2001 Tucson Show. A 3.5 cm octahedron dominates the showy cluster of translucent, lightly etched fluorites nicely placed on the complimentary matrix. Ex. Dave and Emily Stoudt Collection and according to their catalogue, was purchased at the 2001 Tucson Show. It is excellent for this find.
