This is a one of a kind calcite specimen. Dark tan, translucent and lustrous calcite rhombs growing one atop the other in perfect linestep , formed what appears to be a stalactite. On the other side, is a growth of tan chalcedony which parallels the calcite growth. This is really a neat oddball specimen!
You want a unique Indian calcite??? This is as unique as it gets; a self standing rocketship! From a pedestal of golden calcite around which grew a layer of colorless, drusy quartz, perches an angled, doubly terminated scalenohedron. The color is fascinating, with gemmy, transparent golden calcite accented by the overgrowth of dark brown-black calcite which the calcite crystal later developed on preferential faces. The calcite measures a full 8 cm from tip to tip and has good luster. This is all topped off by a cute accent: a colorless, doubly terminated, stilbite crystal. The stilbite is 1.5 cm across. I HAVE NOT not seen another specimen like it. This is really too "cool" for more words! 2 sides and a down-view are shown.

A 3-dimensional and highly unusual group of large calcites from Cornwall! Surprisingly at first, calcite is quite rare from Cornwall, at least in surviving specimens. This is attractive and nearly pristine. It is complete 3-D, all around, 30 degrees. It was exchanged fro mthe Bally Museum before its dissolution by dealer Simon Harrison, and then sold to collector Tim Sherburn a few years ago. It is one of a VERY FEW good Cornwall calcites I have ever seen of this size and aesthetics.
This gorgeous, display-sized specimen features a totally gemmy 1-cm-long emerald perched dramatically out of sparkling crystallized calcite matrix! A beautiful matrix emerald for the price and size range, and hard to get with such nice calcite as well. In fact, this is good simply as a calcite specimen for the locality. Aside from the front-lower area which is more flat, all the framing crystals along the top are 3-dimensional (more so in person), in good shape, and complete around the edge, even
This one is hard to convey in pics. It is actally a very displayable calcite specimen, no problem. However, it is ALSO a very neat pseudomorph piece! The large discshaped calcites sit ON a cluster of large scalenoedhral crystals that turn out to be FLUORITE that had encased an original calcite crystal, filling in the space and crystallizing on the inside of the growing internal cavity as the calcite dissolved away over time. It reallly is much better in person and in fact, could be photo'd the other way with the sharp calcite-formed pseudo on top, as well. To me, though, its primarily a calcite with the replacement as an interesting "surprise" bonus.
A very cute, sharp as heck, DEEP GREEN emerald crystal perched amongst contrasting calcite. The emerald is 8 mm tall and extremely well-terminated. This has super deep color, especially for a smaller crystal (small ones are usually more pale)..
A super sharp specimen, with the deepest green color you can ask for in an emerald and gemminess to boot...I think that is obvious from the photos! The gem crystal is 1 cm tall and perched nicely in matrix of crystallized calcite to make for a very balanced thumbnail specimen. Small, but of the utmost quality!
A fat, barrel-shaped, 1.4-cm emerald crysatl is perched on contrasting stark white calcite, making for a wonderful display piece that gives you a good matrix emerald crystal without breaking the bank. As with teh above, this is one of the best quality emeralds for the price that I have been able to offer. It is hard now, to find reasonably priced specimens
An intricate, complex, twinned calcite crystal that is nearly a complete floater, with just a small attachment in the bottom -rear. The symmetry and patterning, in person, is really mesmerizing and this is unlike anything I have yet seen from Dalnegorsk! MUCH BETTER IN PERSON. I know it LOOKS curvy and cockeyed atop, but that is a visual illusion of the twinning - in person you can see it is pristine and sharply terminated all around, with a bit of included matrix near the base casting shadows from within.
WOW! THIS IS THE SINGLE MOST IMPRESSIVE EMERALD I HAVE EVER OFFERED under $5000. It just came to me a t a good price, and I am trying to pass it on. This glowing green crystal is as thick as a finger and dramatic as hell. It measures 1.5 cm across and is just over 2.5 cm long complete, and then a bit longer with a slender tapering into the matrix. It has top, glassy lustre and a juicy rich color you always want in an emerald. The termination is wonderful, and has a few intricate bevels on the side by way of accent. The black calcite provides the best possible contrast and visual enhancement of the deep green hue, on emerald specimens, and this matrix is very rare. You would think that white works best as background but, in fact, the black calcite somehow visually enhances the green hue of the emerald. The specimen is a miniature, but the crystal is huge and the piece has visual impact that can be seen from across a room.

This is an Elmwood specimen from the famous late 1970s "jewel pocket", that was recently traded to me out of the collection of the Benjamins, friends in France known for their exquisite taste in fluorite nad clacite in particular. It was formerly owned by Keith Proctor, who obtained it from the Steve Neely Collection, which was sold in 1997. This pocket remains one of the most famous and desired of all Elmwood calcite finds, and the gemmy quality, sparkling lustre, and sheer transparency of the crystals sets a standard hard to beat. I think its pretty obvious why they nicknamed it, that. Most crystals were 1-2 inches. some few in good condition reached 4-6 inches. I showed it to Steve Neely recently, just after my trade with the owners, and he recognized it immediately. Most have damage. THIS ONE does not. not a ding. Most specimens from this pocket consist of a single isolated crystal sitting flat on shards of gray dolomite, which detracts from the light transmission through the crystals, and means that too much ugly gray rock is often present. Not this one. In this piece, the calcite itself is central, and a few shards of the matrix extend elegantly from the calcite and behind it in a way that enhances the calcite by immediately conveying how damned gemmy it is. It is GEM CLEAR throughout. you are looking right through the whole crystal in the photo, in its core over 3 cm thick, to the extension of matrix on its backside which reaches out to host the accessory crystal. The real prize, though,is that this piece has a secondary crystal which is even jewellier and gemmier than the first, just a perfect gem hanging off the extended matrix. The large crystal has the sharpest terminations you can ask for, and the smaller one has the more rare, fat termination with multiple facets. So you have two slightly differnt styles on the same specimen, complementing. Overall , it is simply one of the most elegant such pieces I have seen, is a good size, and displays impressively well without the usual bulk of matrix required to stably show such a large gem crystal. This piece, its a miracle it survived intact. And then getting it home on the plane through post-1-small-bag security through Charles de Gaulle, ugh. But I can say that it even impressed the security people on the jetwayin Paris, at least. Bottom line, this is one of the finest calcites from ANY locality that i have ever owned or offered - and I am/was a calcite collector. The pedigree of previous owners could mean nothing if the value wasn't there as a specimen, but since it IS a killer, you can see why it fit in each of those collections. Proctor specialized in Gem Crystals and it certainly fits the bill there more than most calcites; Neely in just damned good small cab and cabinet sized specimens period, but particularly Elmwood material; and the Benjamins specialize in calcite - but mostly in PRISTINE and elegant aesthetics. The price is POR not because it is so much money i am embarrassed to say, but rather because a lot of people have an understandable difficulty in evaluating Elmwood material at this price and quality range, given that the mine produced so much tonnage and the next tier down in quality is, frankly, kinda cheap for what you get in quality. But here is the rub...it WAS only a perception that good things were cheap all along. Elmwood closed years ago now, and the good stuff stopped flowing much earlier, but even at the time a piece like this commanded a super premium over the bulk mine-run material, make no mistake. Truly oustanding Elmwood material is not available today, at any price, near as I can see.

From the noted collection of Chinese minerals assembled by Steve Smale, this is a superb and very unusual fluorite for the location. NO DAMAGE AND COMPLETE ALL AROUND! Seldom do you get crystals so large and gemmy! Also, it has an almost neon, saturated color intensity like you seldom see. The top picture conveys it best, but even that pales in comparison to the real specimen in person. Note also the sharp internal phantoms, again rare in a Chinese fluorite of such size. The piece is a floater! It is symmetric on front and sides, and then roughly complete all around the backside where it has many microfaces formed where the fluorite grew against another mineral. This is NOT your average China fluorite!!! I recently exchanged this from the Smale collection.
A stunning, gemmy, WATER CLEAR crystal with incredible lustre, on a pedestal of smalle rones. NEW FIND of shocking quality from France! I have seen just a few on the market, from only one source, recently. This is some of the finest gem calcite I have yet seen, and i am told the find was very small!
A beautiful spray of gently curved, 2.7-cm-tall emerald curving up the face of these large, sharp calcites! The piece is very unusual, in its aesthetics, and makes for a very balanced miniature wiht incredibly bright color to it. the sharp form of the calcite contrasts starkly with the classic hexagonal beryl crystals in the middle . The emeralds are a rich and vibrant green, of high gemminess and brightness, and BETTER IN PERSON!

A truly unusual specimen! This calcite, doubly-terminated and in a cluster of smaller calcites, somehow glommed on to one of those usually floater etched corners, formed from strange chemical processes in which large cubic fluorites from this mine sometimes decay into 4 corners that then come apart and fall gently into the pocket over time. Somehow, the corner must have gently landed on this calcite as it was forming ,as the two are intergrown and totally attached. The fluorite must have formedlong before, thus. This fluorite corner is complete and features the full stalk into what would have been the center of a cube. It has the sharp corner, however, remaining...when I was a kids some people labelled these as "fluorite pseudo after calcite," because they looked so crudely scalenohedral themselves. But, they really are fluorites, just of odd form. Try finding another one in matrix! Let me tell you, they are rare anyways in a cluster or attached to fluorite, but VANISHINGLY rare attached to a calcite like this! And, aesthetically attached, to boot.
