We have grabbed every specimen of this amazing stuff we could find, yet we have seen only a handful. I believe this is our last one. The crystals are an amazing shocking pink - in this case, isolated from one anotheron the matrix rather than massed together. 6.8 x 3.8 x 2.4 cm
This superb calcite did not photograph well at all - in person, it is GEMMY, not milky as the photo seems to suggest due to the reflections! It is a gorgeously-formed scalenohedral crystal intergrown with a smaller one, both complete all around, pristine and beautifully terminated, on a perfectly-trimmed matrix. This is a superb Dalnegorsk specimen, and because the shots are not so good, we will GUARANTEE super satisfaction if you win this piece! 6.2 x 5.0 x 4.9 cm
A 1.5-cm, deep red, super-lustrous crystal of cinnabar of excellent form, against a background of calcite wrapped around a quartz point. 5.4 x 3.5 x 2.2 cm
A STRIKING and DRAMATIC, two-sided CABINET specimen of highly lustrous, colorless to milky-white, stepped, blocky calcite rhombs preferentially dusted with chalcopyrite crystals. One side is nicely accented by a 3.5 cm, salmon-pink barite blade. This is CLASSIC, OLD-TIME material from the famous St. Joe #3 Mine at Balmat, New York. Very minimal bruising on such a large piece. Ex Gene Bigwarfe and Ken Hollman Collections. 14.2 x 9.5 x 8.3 cm
A beautiful and showy specimen of two generations of calcite with pyrite from the W.H. Leithauser Collection. A cream-colored calcite rhomb is partially covered with lustrous, pyrite cubes and is surrounded by lustrous, colorless nailhead calcite crystals. 5.8 x 4.7 x 3.5 cm
Three intergrown balls of calcite tinted a pretty grey color by inclusions of boulangerite. Floater! Exquisite! 3.0 x 1.7 x 1.6 cm
Pretty green malachite crystals on bursts of gemmy calcites - a wonderful old Bisbee thumber, obviously hard to get these days! 3.0 x 2.7 x 2.3 cm
A complex, stepped crystal of purple fluorite decorated with little rice-like calcites. 2.8 x 2.7 x 2.5 cm
From a onetime find in Peru in the early 90s, this is said to be one of the very best specimens (the other being a famous thumbnail in the Ralph Clark Collection). This specimen, from the Peruvian subcollection of Cal and Kerith Graeber, is an attractive miniature overall and features two SHARP, LEMON-YELLOW crystals of 4.5 to 6 mm on edge. The helvites are sharply tetrahedral in form, and they are so sharp and colorful they look fake. It is a supremely good rarity, and a classic form Peru that is almost unobtainable. 5 x 4 x 3 cm
Colorless rhombohedrons of calcite from Tsumeb are generally cloudy and, therefore, only translucent. This, however, is an exceptional difference. A series of 3.0 cm across calcite rhombs are colorless, mostly transparent, lustrous, and perched aesthetically across a ridge of matrix which has been dusted a pale green, possibly by mottramite. There is minor peripheral contact, but it does not affect this superb display specimen. Fine Tsumeb specimens, like this one, have been harder to find since the closing of the mine. The line of crystals is very 3-dimensional, and dramatic - better in PERSON! 13.6 x 6.3 x 4.1 cm
An incredible piece for the size! This has the finest quality and gemminess you can ask for. the tips of the crystals are sharp, and lustrous, and to 4 cm. It has highest luster, gemminess, and just superb 3-D aesthetics! Marty was one of the locals around when Collectors Edge was mining this material, and bought one of the best of the finds. This IS superb, and worthy of the collection he built, and any other. 5.9 x 5.4 x 4.8 cm
Over the past year, a batch of really fine, gemmy cobaltian calcites has leaked out of Bou Azzer and made its way to various dealers. I have been grabbing the good ones as I see them at a decent price, because specimens of this quality are just so desirable and otherwise hard to come by. This one has a rounded matrix COVERED with gemmy pyramidal crystals. 5.4 x 4.5 x 3.5 cm
A fine and uncommon calcite butterfly-twin from Dalnegorsk, complete all around, with good transparency. The Bor Pit has been turning out calcites in a dizzying array of forms, but twins like this are still very rare. 3.5 x 3.5 x 1.3 cm
It was just impossible to capture the dazzle of this JEWEL-LIKE large calcite crystal, capped with a second crystal that grew right on the termination. It is so much like fine crystal that it actually throws off flashing spectral colors in person. The side faces are glassy-smooth, and the faces of the termination have gorgeous striations on them. SO MUCH better in person – satisfaction absolutely guaranteed! 7.5 x 7.1 x 5.3 cm
Is this not COOL!? It is a large and super-showy example of a very unusual crystal form for calcite, difficult to describe, but basically doubly-terminated, golden crystals (to over 10 cm!!) that look as if they are composites of dozens of smaller crystals. The calcites are completely exposed on a dramatically contrasting matrix of dark fluorite that really lends them pizzazz. The fluorite is composed of flat shards, out of an Escher painting, one atop another and cemented together by calcite. On the back is a minor amount of limestone matrix, as well. Basically, the piece is just dramatic and weird....and quite good, i think. There are crystals on both the front and back. This wonderful specimen came out of the collection of Tom Wiesner. 18.5 x 16.9 x 9.8 cm
