8 x 8 x 3.8 cm. You have probably noticed that we have not had much Elmwood material lately, because there is not that much to be had since the mine closed. Here, however, is a large and beautiful combo piece from the mine - gemmy crystals of fluorite with a flowery barite ball of high quality for the barite itself in any case! The fluorites here, to one centimeter, are light purple with very unusual (for the Elmwood) speckles of intense deep purple inside.
6.4 x 4.9 x 4.5 cm. A SUPERB 2-cm cube of gemmy fluorite, sharp as a razor, with a beautiful purple blush centered in the crystal, surrounded by muscovite. Henry Minot specimen.
9.2 x 8.1 x 3.2 cm. From the new finds at the Okarusu - a plate of translucent crystals with purple and green tones and a silky luster - with one crystal that stands out at 3.5 cm with a sharp green and purple phantom inside! (That chinky you see in the corner is a natural modification and is NOT damage).
3.4 x 1.9 x 1.7 cm. This is from the recent find at Clay Center, and is just a pristine and ADORABLE example from the find, perfect for a thumbnail collector (could hardly be better). The pristine fluorite (1.3 cm) is perched on a shard of celestine; as you can see, it has a sharp golden phantom inside a more light-colored exterior. Fine luster, too.
22.2 x 15.0 x 8.6 cm. A very large, very rich specimen of fluorite from a CLASSIC American locality! This cluster of translucent green fluorites includes crystals that measure to over 4 cm across! They are not the most beautiful crystals in the world for color, but there is only minimal wear and it’s remarkably well preserved, overall still very impressive for the SIZE of the crystals and their significance. This is certainly a very impressive locality piece.
20.1 x 17.4 x 11.9 cm. A VERY LARGE showstopper of a fluorite specimen from China! These crystals are superbly sharp, with a beautiful silky luster. They are in wonderful condition. The crystals measure to 3 cm along the edge, though most are closer to 2 cm. As you can see, the matrix shows between the crystals in places, adding to the attractiveness of the specimen (rather than their being simply massed and piled up). Magnificent!
8.9 x 6.1 x 4.5 cm. You might be familiar with the wonderful translucent, spherical yellow fluorites from here that are prized by collectors. But here is a large one (3.75 cm across) that is wrapped in lustrous amethyst crystals - adding even more appeal! Extremely rare association!
4.9 x 1.9 x 1.4 cm. This glassy (in person) quartz crystal is decorated with colorful little crystals of iridescent pyrite, as well as micro lavender fluorites, with a really beautiful result!
8.4 x 6.6 x 4.9 cm. The crystal forms on this specimen of light blue fluorite from China are so modified that it is hard to distinguish the underlying forms - except for one perfectly-formed and sharp octahedron on one side of the specimen! There are pretty little gemmy poker-chip calcites accenting the area of the octahedron. No damage, just a landscape of micro-stepped faces intermixed with small flat faces, and the one octahedron. Ex. Smale collection.
6.3 x 1.8 x 1.4 cm. This find of around two years ago in Madagascar was just so exciting - because rarely do you get inclusions as striking and dramatic as this. Inside this clear quartz crystal, you can clearly see three purple fluorite crystals (one of them smaller than the other two) that formed on the surface of the quartz crystal as it was growing, and then were engulfed when the quartz continued to grow after that. Now there they are, floating mysteriously inside the quartz! This one is in great shape, too.
10.5 x 7.9 x 4.5 cm. Sorry about the color in the pic - it was very hard to capture the fluorites and the matrix together without one or the other going haywire. But, in person, these fluorite crystals are a pretty light green, with a rough cuboctahedral form, on a matrix of colorless fluorite that sits on a base of quartz. The fluorites measure up to 2.4 cm.
3.2 x 2.4 x 1.5 cm. A gemmy and lustrous, 1.2 cm, cuboctahedral, dark purple fluorite crystal aesthetically set on matrix. This fine fluorite is from a very small find at an UNCOMMON Argentina locality - Laguna Brava in Cordoba Province. A textbook and pretty cuboct. No telling if and when I will get more, this was a onetime find, perhaps.
5.4 x 4.9 x 4.8 cm. Pretty, lustrous, translucent and frosted, purple fluorite cubes to 1.5 cm are nicely set on contrasting white matrix and beautifully complimented by lustrous, brass-yellow pyritohedrons on this showy and fine specimen from the famous and historic San Martin Mine of Zacatecas, Mexico. This ancient mine is still operational after 400 years!
19.3 x 12.6 x 5.3 cm. A translucent plate of unusual quality in terms of both its aesthetic horizon at the top, and the translucency of the fluorite itself. Most larger "bubbles" are thicker, and so transmit little light through the core. This one, however, has formed thinly to start with the bubble rising only so much from the crust as to make it look spherical when in fact it is hemispherical. For my tastes, this is one of the best specimens of this material I have seen come out in a trickle since they first appeared at Munich 2006. It is pristine, beautiful, and just plain unusual material!
6.2 x 5.7 x 4.3 cm. A beautiful thick hemisphere that glows when backlit, not quite completely formed but contacted, not damaged, at the edges.
