An unusual specimen of a style I have not seen since the 1980s, this is so-called "angle-plated quartz" in which the quartz has filled seams and preserved the gaps between some other mineral species' crystals. It is a weird thing, in perso, and I cannot recall anybody ever giving me a solid explanation of how these form beyond guesses as to what mineral replacement or mineral cavity they were filling. This is an excellent specimen with dramatic form, and good size, and clean stark white color. It has a sugary sparkle to it from a coating of microcrystallized quartz atop the larger gridwork.

A very unusual citylike cluster of elongated, tapering aquas, from a new locale. This was picked up by Dr. Emanuele Marini on site, in his travels there. I have not see others, and he told me the find was quite small. It is slightly etched, and looks frosted on the surface, thus. They are quite unique! The piece is complete all around except a small bit in back, and sits nicely on its own. A small quartz crystal sits atop

This specimen, in person, looks much more complex and mesmerizing. For my taste, it is one of the better miniature sized examples of this species I have seen, because of the balance and association. It features a nearly 3-cm-long gem phenakite crystal perched on a tree-like smoky quartz, that comes to a stepped, sharp termination. The whole quartz point is complete all around. The termination is accented be small gem phenakites at its tip, and behind like bracing struts. The aesthetics are striking, and the contrast of white on dark makes the piece MUCH more appealing to my eye than the rest of these specimens I saw, which are generally white phenakite on white matrix. This exceptional miniature was cherrypicked by a European friend travelling in Burma, who has obtained and exported much of this material over the years. They only come from very tough rock, mined with hand tools, and in very small pockets.

Usually, papagoite is dispersed in veils, but in this piece it is extremely concentrated in richness and in color saturation, right at the tip! This is a phenomenal crystal with unusually vivid coloration. The termination is sharp and complete, unusually pristine. Note also the slight wisps of copper inside, dispersed in the zone of deep blue papagoite. A classic, unique to this locality, such crystals are highly desirable in this quality. Papagoite is much rarer, here, than the ajoite inclusions. MUCH better in person, this is one of the sharpest such examples that I expect to be able to offer. It is from new finds in late 2009.

This is a razor-sharp crystal with a termination so sharp you can literally cut yourself on it. The quartz hosts an internal phantom generation of quartz, that is richly included by powder blue ajoite. Now, often the inclusions are dispersed in the quartz , but seldom do you see a phantom within, concentrating the color as this one does. The crystal is complete all around, and shows extraordinary clarity looking through to the phantom zone within. I have seen literally hundreds of these, and in this size range, few have stood out to me as starkly as this piece, which I saw at the Munich show with a direct source. Moreover, it is complete and sharp, and shows off the inclusions without need of polishing. It really is one of the sharpest and finest in its size class. After cleaning, we found that it is technically a floater - rough at the bottom, but microcrystallized and complete.

This unusual specimen has BOTH rare blue species included within it, AND is a floater cluster of quartz, as a bonus. Clusters in good condition are not so common, and usually they are bigger anyhow. Most small pieces from here are singles - the mine likes to grow its quartz big. Only rarely do you get both minerals included within the same piece, and here you have it in both of the conjoined quartzes. The papagoite is the darker blue, and ajoite the lighter blue. Both are present at the edge boundary of an unusual, internal phantom in the upright crystal. The quartz cluster broke away from its matrix in geologic time an drehealed on the bottom, thus making this a floater, complete all around. Remarkably, it is pristine.

This is a natural jewel! A 3.25-cm-across, doubly-terminated quartz is just floating on the surface of this lustrous, reflective quartz shard - the whole thing a floater! It is "just quartz " on quartz, at som elevel. But on another level, it’s a very special and unique piece that really captured my attention. ex Franz Saller collection

The quartz hosts an internal phantom generation of quartz, that is richly included by deep blue papagoite. Now, often the inclusions are dispersed in the quartz , but seldom do you see a phantom within. Here, the phantom somehow concentrated the papagoite, so that the papagoite marks the entire right edge of the original phantom crystal inside. The crystal is complete all around, and shows extraordinary clarity looking through to the phantom zone within. I have seen literally hundreds of these, and in this size range, few have stood out to me as starkly as this piece, which I saw at the Munich show with a direct source (these few i offer here all apparently came from the same pocket, as they are similar in size and unusual sharpness and transparency). Moreover, it is complete and sharp, and shows off the inclusions without need of polishing.

I have seen only a very few blue topaz in matrix from Brazil, and not another such as this, with a sharp blue gem perched on a large quartz crystal! At 8 x 7.5 x 4 cm, the topaz is a good size and significant on its own, and it is literally stuck in a crevasse between two intergrown quartz points. The quartz is terminated, thought etched in back. It is even nearly pristine - just a few very trivial dings mar the large quartz. The topaz itself is pristine and complete all around except for a few very nearly invisible contact points where it attached to another bit of quartz. Even its underside is floating free and clear of the quartz and is roughly terminated, making it a "floater". The top termination is SHARP and has a broad chisel-point termination, leading to razor-sharp, etched side faces. Small bits of sparkling, micaceous-looking lepidolite cling to the center of the topaz and run down its front in a vein , to the quartz. Overall, this is a unique specimen, large and impactful as it sets the topaz high up and easily lit. In fact, the photos do not do it justice. When backlit, the light goes through the quartz and topaz both, and the piece glows. I have not seen another like this, and certainly I feel at the price point, another is unlikely. It could as easily be twice the price, but that I got it reasonably myself in a large specimen, in need of a trim. So we took off a big chunk of massive quartz at the bottom, and now the piece stands quite nicely on its own, and is more balanced.

This is an outstanding, GLASSY AND GEMMY cluster of amethyst from this famous and very sparsely producing locale. It has the deepest purple, grape-juice colored amethyst cores you could want, grading to a clear zone at the very tips. The display face you can look right down into, as the glassy, transparent surfaces facing front let you look deep within. Having handled a number of these, including the famous Romero collection pieces, I can say that while not the biggest, this is among the best for quality you can ask for. It is nearly pristine, and in fact you have to look really close to find just one ding on the front at all (a tiny nick off the smaller sub-termination). Although larger amethyst crystals occur elsewhere, for my tastes the combination of the color and qualities in great Guerrero material make them the world's best of species. This is an excellent example of why I say that. It is from the Marc Weill collection, but would have been most likely mined in the 1970s or 1980s.

Firstly, this specimen is NOT REPAIRED as so many of these classic combos are, today on the market. Also, it is from the older classic locales near Florissant, near to but not from the modern Smoky Hawk claims. It is probably 1960s-1970s vintage, but no way to tell for sure now. The specimen has all the qualities you would want in a combo from here, but without the typically high prices they go for (all things being relative) as i exchanged it from a collection at a fair trade price: great color amazonite; great color smokies; translucence to the quartz; and overall good aesthetics. AND, it has no repairs, which i find remarkable. It is pristine and undamaged, with a great horizon edge to any display angle. At 5 inches across, its of good size, too. A modern specimen of such aspect (with repairs) might run around 20k on the open market these days. ex Steve Neely collection, with label.

This is a stunning specimen of rutile included inside quartz...rather, in a giant elongated , floater quartz crystal! THE RUTILE NEEDLES ARE 7 INCHES LONG! I have never seen a piece like this, with such large rutiles, included precisely along the c-axis so that their whole length is enclosed. Usually the inclusions are not lined up on the long axis, and so the quartz cannot possibly hold the full terminations (even of small rutile crystals). Here, we have rutile complete from tip to tip, 7 inches later. The color of the rutile is red-orange, a RICH hue, not the usual yellow-orange or brown shades of rutile. So, it really stands out to the viewer. The contrast of symmetries and color, and of the acicular rutile inside to the sharp faces of the enclosing quartz, is more dramatic than one normally sees (usually there is just no alignment, no symmetrical relationship). I have seen literally thousands of rutile in quartz specimens and few transcend to this level of import and interest to me. I showed it to other sophisticated colelctors who normally would not register a "common oddity" such as this , and all were equally impressed. In fact , I elicited a few choice phrases from one normally conservative and polite collector. The piece is 735 grams, and complete all around except for a small growth contact on one terminal face. A remarkable, rare quartz specimen of the top calibre to my mind. Apparently an older specimen kept in teh stash of a Brazilian source, this turned up at the Tucson 2010 show.

This rutilated quartz is unusual in that the quartz itself has a tabular shape, like a flattened parallelogram almost, that we call "tabular." Tabular quartz is seen often from some locales, and is rare from others. From the rutilated quartz localities, I simply have not seen such a piece before. The rutile is rich and bright inside, and the piece has good color overall. The contrast of the spraying needles inside to the flat faces outside makes the specimen appealing, visually; but the knowledge of the rarity of the tabular , elongated quartz habit also adds a level of interest to me (and I would not care as much if it were bashed or incomplete - but this IS a terminated-all-around floater in good condition, too !).

Probably dating to the 1980s heyday here, this is a 2 kilo GEM crystal of alpine smoky quartz, of a quality normally only associated for brightness and clarity with the Swiss and French Alps. However, Russia also had a few! This locality, in its heyday, produced an exquisite suite of alpine cleft type minerals. The smokies were generally smaller, and more pale, smoky to gray in color. This bright quality and intense color, combined with gemminess, are a rarity. In excellent condition, this is complete all around with no significant wear, save only at the lower part of its base (and that is mostly contact, not damage). This specimen was exported from Russia by dealer Daniel Trinchillo in the 1990s, and was then appropriated/purchased by his father , a well-known quartz collector, before it ever hit the market.

This is a highly important specimen for what it is, not just for the massive amount of crystallized silver present but also for the locale. Silver Islet is a famous old location mined circa early 1900s. It is now closed and gone forever. It was one of those funny stories in mining that you hear about and cannot believe - they actually mined this silver from an islet in the Great Lakes, while pumping water out from behind barricades. Verifiable Silver Islet specimens are few and far between. This is typical of the style and matrix association, and comes from the private silver species collection of a dealer known to specialize in such pieces, and verified by Rod Tyson (an expert on such). However, one seldom sees anything beyond small pieces from here. This monster, at 455 grams and complete all around as a display quality specimen, is truly significant. Comes with custom lucite display base. Ex. Charles Leavitt Collection (well known for a large and diverse silver suite).
