This UNUSUAL Chinese specimen consists of a thin crust of fluorite upon which grew, nearly-colorless, transparent, lustrous, intergrown crystals of fluorite, to 1.5 cm across. Very pretty and eye catching, liks cubes of ICE ! 11.5 x 5.7 x 1.2 cm
On a matrix of sugary-looking, white quartz are aesthetically perched, several,brown, lustrous, scheelite crystals, to 2.5 cm across. All the sparkly, sugar-like material from the halfway point of the piece down is a thin druse of colorless, beautiful, sparkling FLUORITE overlaying the qartz matrix and part of the scheelite pocket! The scheelites are supremely good for the locality and have a rich wet lustre to them! This is a spectacular specimen for the locality for both the size overall and the perch on quartz as you see it. Most unusual also, because of the fluorite association. A few scheelite crystals are even doubly terminated. Normally the Colorado scheelites do not do a lot for me, but this is special! Comes with base. 8 x 7.2 x 6.5 cm
A fantastic, I’d say even competition-quality Elmwood fluorite specimen. It was incredible how quickly the good specimens disappeared from the market after the mine closed, especially with the mine having been so prolific. Now, sadly, you just don’t see that many killer specimens around for sale. The crystal here measures 1.7 cm on edge, is perched perfectly on a bit of matrix, and is accented by a smaller fluorite and some little red sphalerites. You do not see many Elmwood fluorites better than this in this size range. 4 x 3.2 x 3 cm
These spherical yellow fluorites are cool enough on any matrix, but check this one out on light purple AMETHYST! The fluorite measures 3 cm across. 8 x 5.5 x 4 cm
These spherical yellow fluorites are cool enough on any matrix, but check this one out on AMETHYST! This specimen has a smaller fluorite than the other in this update, but it is nicely perched over a field of gemmy (in this case) amethyst crystals. Another ball of fluorite is encased in the amethyst behind it. 11.5 x 9 x 6.5 cm
Dalnegorsk fluorites are notoriously hard to photograph, so they always look better in person than the pics show. At any rate, this specimen is from 2003 mining, and the crystals show the super-complex modifications to the octahedron that characterized the specimens from the Nikolaevsky that year. The crystals are WATER-CLEAR on the interior, with glassy faces – like cut glass! The crystals measure to 1.5 cm and are piled up richly on the matrix. A flashy Dalnegorsk classic, BETTER IN PERSON! 9 x 8 x 5.5 cm
A fine specimen of the rare and desirable pink shade of fluorite, from Peru. These transparent octahedrons (to 1.5 cm) are made particularly attractive by a blush of green in the center of the specimen. The crystals are wrapped 360 degrees around a small bit of matrix in the center-bottom of the specimen, which you can actually see through some of the crystals. These were found in the late 1980s. Beautiful! 5 x 4.5 x 2.5 cm
This Elmwood piece has SO much going for it. The fluorite is not only large, but it is distinguished by prominently showcasing two (and a smaller one) of the distinctive clear "gem window" corners unique to Elmwood fluorites, providing windows into the gemmy interior. It is these corners that sometimes remain when the fluorite crystals etch away due to corrosive solutions in the pocket that attack corners differently than center faces. In this case, the etching has only just begun on the side faces leaving this pretty contrast between the frosty sides and the glassy corners. This BIG crystal measures 4.5 cm along the edge, so it is truly impressive! It is beautifully wrapped around the sphalerite matrix. There is a small ding on one of the corners. 9 x 7.1 x 5.5 cm
This is an unusually large and significant specimen from a very short-lived mining operation in a very inhospitable part of the Sahara Desert. In fact, the two guys who were mining these eventually gave up, because they could only find specimens few at a time, through great labor in the horrible heat or cold (depending on the season), and could not find rich pockets. So, there are very few of these out there. They are VERY distinctive fluorites, with a gorgeous silky luster, glowing purple transparency, and flattened rectangular crystals. There are just a few small cleaves here, but none too visually detracting and in any case quite forgivable considering the size and rarity. 9 x 7 x 6 cm
You just do NOT see many pieces like this left around on the market, with the rush to lock up good Elmwood pieces over the past two years. This combo piece has it all: the MOST desirable fluorites, with unusual transparency and super luster, to 2 cm; and, highly lustrous crystals of sphalerite that form a perfect setting for it. I could find only a couple of little contacts on the fluorites, but you have to look for them. 8.5 x 6.5 x 5 cm
Octahedrons of fluorite with purple and green hues. Matrix covered with dozens of crystals measuring up to 4 cm along the edge. 24 x 21 x 3 cm
11.5 x 9.2 x 7.5 cm. A cluster of tall, slender, elegant quartz crystals, sparkling with little apophyllites, and with phantoms of green fluorite inside the terminations. A sizeable and dramatic Dal'negorsk piece. These interesting combination pieces came out around 2005.
3.7 x 3.0 x 2.6 cm. Vertical cluster of intergrown crystals, extremely translucent, with fluorite association (rare).
4.5 x 3.8 x 2.5 cm

This is a wonderful combination piece, with the clear to frosted Fluorites perched beautifully on the Scheelite. Not only are the Fluorites partially gemmy, but they contain a sharp narrow purple zone and included needles of what may be Ferberite. A very aesthetic and well-balanced thumbnail specimen, indeed. The locality is not only classic, but is long-defunct!
