A striking crystal of rhombohedral calcite with the shocking pink color that made this find so obviously desirable! BETTER and even more intense color, in person!
I have never seen another calcite quite like this from the location - while the curvaceous form is not unusual, the sparkling coating of secondary calcite IS most unusual, and gives the piece a unique appearance. It is a truly elegant, colorful specimen that is better in person
This specimen is a large 3-dimensional knob that USED to be calcite but has now been entirely converted into sparkly purple fluorite. The color stinks in the photos but in person it IS rather purple, I assure you. It also is prettier. The calcite scalenohedrons are small, to 1 cm, and in person you can see tha tht especimen is literally made up of them though here it looks like a lump. BETTER IN PERSON! I think, given the size and condition of the specimen, that this is a really significant piece!
This unique specimen has such startling color contrast between the green and the white that it looks fake, almost. The piece features a wonderful gem green fluorite that is translucent to transparent, on which is perched smartly a doubly-terminated crystal of calcite that has been changed over to quartz! I have never seen the like from China and it seems a one-off specimen that I found in amongst a lot of fluorite with just a few other specimens showing association with quartz casts but no sharp pseudos like this one. Oh - almost forgot to mention those two internal white spots you see in the fluorite are actually 2 more small pseudos, INCLUDED INSIDE THE FLUORITE!
A surreal stalactitic growth of calcite, culminating in a crystallized knob atop, and with a bizarre and very eyecatching satellite system of "rings" rotating around it like hula hoops! Never seen a calcite quite like this!
Another bizarre and asymmetrical stalactite with secondary growth in a halor or hoop pattern around the main stalk, just plain weird! It looks like a spinning dancer with arms up around the chest
From the same pocket, a LARGER and more dramatic, complex specimen built up of iron-stained rhombohedral calcites with a pleasing reddish hue , perched atop an earlier generation of hematite-coated , matte-textured calcite of a different habit entirely (scalenohedral).
An intricate, animal-like "sculpture" of calcite that is NOT a stalactite as these are fully crystallized and not formed by drip action, though you may think at first glance they are. Each of the major upright crystals is 4 cm or so! This is complete and pristine all around!
This specimen was one of the first pieces out to market, last year, in a trickle tha tcame out which led me to pursue this find. It has a muted, but beautiful, tangerine color to the crystals which is quite nice. The white is calcite, which has not been burned off. Probably, it can be taken off, but I liked the contrast! Very little damage, and unique aesthetics, make this a special prize.

Illustrated in ExtraLapis: Calcite issue, page 8, AS THE STEREOTYPICAL EXAMPLE OF A SHARP CALCITE RHOMBOHEDRON in a discussion of the forms of calcite, this is a truly spectacular example of the classical rhombohedral form of calcite, from Tsumeb. The huge calcite rhomb is colorless, lustrous, transparent and measures to 4 cm on edge. The matrix of copper has a green patina, and is laced with tiny copper included calcite crystals. This is an elegant calcite matrix piece from the heyday of Tsumeb. It is perfect in form and symmetry and undamage save for a VERY minor bruising along one edge of the lower left (that could be ameliorated with acid if desired. its so minor i wouldn't bother). This was exchanged by me recently from the well-known calcite collection of Francis Benjamin.
A rare, classic ullmanite from this important locality! It is not the type locale, but is probably the more famous as many fine specimens were collected here in the early to mid-1800s. Recently, some friends of mine have reworked these old mines and found a few specimens I was happy to get. This is one of the more dramatic and showy, featuring bright, starkly cubic ullmanite crystals (to 4mm) on contrasting calcite. I have not seen good ullmanite for sale in 4-5 years, now, so this is a good chance to grab one! Also, the piece is very richly covered, as a bonus.
This matrix specimen, one of the best from Morocco that I have yet seen for sale, is covered with rose-pink, sparkling, translucent crystals of cobaltoan calcite to almost 1.0 cm in length. The color is so vibrant that it almost has a neon effect. The pink is the hue of the best rose quartz, better than almost any other specimen of this style I have seen. The lustre is like glass, sparkling! The piece is NEARLY pristine, with just a small bit of the periphery contacted, and a few very minute dings; but as you can see the display face is awsesome. In person, this is a very 3-dimensional specimen as well, with great visual impact - it is hard to convey in the photos the depth , because the crystals stick out every which way.
From a small find that was brought out at Munich, these are specimens I bought there a tthe show in 2006 but only got ahold of in a shipment back to me at Tucson. These are VERY unusual crystals in that they are hollow casts after calcite, and the coating is a true mixture of sphalerite and siderite (almost an amalgam?!). They have been extensively analysed in South Africa, to come up with this conclusion. So far as I am awware, this is a first. I selected just a few specimens on the run at Munich with regards to getting pieces with superior 3-dimensional form, a good surface shimmer (almost metallic!), and no damage. I think these pieces were, from what I saw, among the best for quality that could be had. This one is a complete crystal, all around, very 3-dimensional (more so in person!)

This specimen is one of the bettre clusters I saw, for the size, and has a wonderful surface sheen and shimmer to it, much more evident and almost golden, in person!

Much great material has come from this mine recently, including a new cache of intense, saturated pink cobalt-rich calcite specimens. I love the stuff and bought a lot of it, but one piece really stood out to me amidst all i have seen (including at Tucson). This piece, which I actually bought from a dealer during setup at the Munich show, and only just got back at Tucson trimmed and cleaned, is for my taste the best example I know of in this size range combined with overall quality. It is a double-ended stalactitic growth, perched on a stalk of calcite below. Although contacted in back, it is complete and absolutely pristine on the front, sides, and top. The display value in a case, for sheer color alone, is stunning. But really, at the end of the day, so many of these new pieces are just flat plates, and so few have the kind of 3-dimensional relief which we have here, that I think it a highly special piece worthy of advanced collections. Comes with custom lucite base for display. There are few minerals you can buy, that are of high quality and pack so much color saturation punch in a case as this one.
