11.1 x 6.4 x 5.4 cm. A large cluster of transparent quartz crystals from Romania - which we hear is on the verge of being shut down for mineral mining. These crystals measure to 2.5 cm, and have super luster.
6.7 x 5.5 x 4.1 cm. Kyanite is well-known from North Carolina, though not nearly as common as from Brazil in specimens of course. However, unlike with the Brazilian ones, it is VERY rare to find an intense blue GEMMY crystal like this -- which explains why it was in the Barlow Collection (specimen #B210). This fine, beautiful crystal, terminated on one end, measures 6 cm. It is not only comparable in crystal quality to Brazilian material which in this quality is already uncommon and expensive, but from a US locality not known for this kind of quality by any stretch. It surely is a standout one would not expect in a US minerals collection, I would say. It is surely an old specimen. It came from the collection of F. John Barlow, dispersed in 1998.
14.5 x 4.9 x 3.8 cm. A complete stalactite, and a sizeable one, covered with sparkling amethyst crystals. This stalactite is undamaged, with the tip intact. Underneath, where it was removed from the pocket wall, you can see the "core" with concentric rings indicating that deposition that formed it until the crystals began to grow on the periphery as a final decoration.
6.7 x 2.6 x 1.5 cm, 6.2 x 2.1 x 1.9 cm, 5.4 x 1.6 x 1.5 cm, 4.9 x 1.4 x 1.2 cm.
FOUR fine crystals of Brandberg amethyst, with the characteristic brightness and glassy luster. They show a variety of internal appearances, including smoky and amethystine blushes. One of them has little red inclusions of lepidocrocite inside.
11.3 x 10.3 x 3.6 cm. A showy and excellent CABINET Pennsylvania copper with quartz and matrix! This sculptural and uncommonly large copper has a nice patina. The copper is platy and hackly. This is a fine piece from a recent, small find.
4.7 x 3.5 x 3.0 cm. A BEAUTIFUL and AESTHETIC divergent spray of very gemmy and glassy, rose-pink quartz crystals from recent finds at the Pitorra Mine of Brazil. This beauty is very nearly pristine, with only a couple of broken crystals on periphery. Classic and textbook rose quartz quality.
5.5 x 3.8 x 2.6 cm. An aesthetic combination specimen from Mt. Malosa, Malawi of a pristine, 3.7 cm, striated, black arfvedsonite crystal jauntily set in off-white feldspar crystals and nicely accented with three, tabular, water-clear, very light smoky quartz crystals. Excellent combination material from this famous locality, with not much new material coming out in the last few years.
26.0 x 10.5 x 7.5 cm. A DRAMATIC and STRIKING doubly terminated LARGE CABINET quartz specimen from the collection of noted Alpine collector, Rolf Wein. The terminations on the huge DT crystal are very nearly pristine, with only the very faintest edge wear on one tip. Most of the large crystal is water-clear, with portions milky or having yellowish limonite stain. The stand-alone termination even has a couple of included rutile needles. The back is nicely complimented by small, hoppered pyritohedrons and pericline crystals. From the famous Hocharn Mountain of the Rauis Valley, Austria.
Charlie had a whole pocket of these strange fluorites, like no others I have personally seen on the market at any time from the area. This is the largest piece from his stash, and is very much more dramatic in person. It features highly modified crystals of fluorite with (for lack of a better word) "bubbly" cubic fluorite outgrowths from oriented faces of an underlaying octahedral fluorite. They are green and gemmy with purple highlights. The piece as a whole is sparkly due to a thin coating of bright little calcites. 14.8 x 12.1 x 7.1 cm
Charlie had only one flat of this very unusual association, which he said was found at the end of the 1990s here. The fluorites here are mattte-green, but translucent, and they sit on contrasting amethyst crystals to 1 cm in size. The largest fluorite on this plate is 2 cm. 6.0 x 5.4 x 2.3 cm
Gemmy, transparent, lavender-colored fluorite crystals perched on the edge of a quartz cluster make for a really distinct specimen, here. 3.6 x 3.2 x 2.7 cm
This specimen comes from the Uis tin mine, from the 1970s or earlier according to Charlie. It features a large freestanding crystal perched on quartz matrix - and the crystal is , in person, translucent and of a nice pastel green color. Such specimens are extremely hard to obtain today and , especially in such aesthetic form, are rare in fluorite collections. 11.8 x 6.8 x 6.5 cm
Charlie had only one flat of this very unusual association, which he said was found at the end of the 1990s. The fluorites here are mattte-green, but translucent, and they sit on contrasting amethyst crystals to 2 cm in size. The largest fluorite on this plate, which is also our largest specimen of the pocket, is 3.6 cm. These are octahedral, translucent crystals and on the edges have oriented outgrowths of minute cubic faces. I cannot think of a fluorite on amethyst association from any other locality . 17.2 x 13.0 x 3.8 cm
This is a schorl specimen so good, I just wasn't even sure at first glance it was...I mean, schorl is usually just black tourmaline, to be discarded as secondary in priority compared to a glorious gemmy crystal of color. But when you get ANY mineral specimen with such sharpness of form, contrast to matrix (crystallized matrix no less, not just rock), and eye appeal, even a traditionally secondary species to the collector can produce a first rate specimen of competition quality. This specimen is complete all around, and pristine save for a few very trivial contacts. 7.7 x 7.5 x 6.1 cm
A brillianlty lustrous cluster of sharp schorl, again on contrasting quartz matrix, shows off how good Erongo schorl can be! It is 3-dimensional, complete all around, and MUCH MUCH BETTER in person! This piece is pristine and complete save for a few very tiny dings or contacts that, in person, do not detract at all. I have seen such clusters before from Erongo, and thought highly of them...but the fact that this is perched upon crystallized smoky quartz takes it to the next level. And, I think the prices on these are pretty reasonable for world class exmaples of their species. 7.5 x 6.2 x 5.4 cm
