6.4 x 4.6 x 3.5 cm. A showy and excellent combination specimen from the very famous and now-closed Sweet Home Mine of Colorado. Very glassy, cuboctahedral fluorite crystals to 6 mm are nicely scattered on needle quartz with cherry-red rhodo rhombs and a patch of sulfides, all on quartz matrix. The fluorites make this a distinctive and desirable specimen.
5.4 x 5.1 x 4.4 cm. An OLD-TIME, CLASSIC and very showy Himalaya Mine specimen. A 3.2 cm, pristine, gemmy and lustrous, green, pink and green tourmaline is very aesthetically attached to the side of a smoky quartz cleavage. The gemmy, green termination really sets the tourmaline off. The old label has a 1923 date on it! This historic piece could easily date to the late 1800s-early 1900s, when the mine was very active for the China trade.
8.5 x 7.3 x 6.5 cm. Lustrous and glassy rose quartz crystals BEAUTIFULLY compliment a large, complete all-around and sharply terminated smoky quartz crystal on this impressive specimen from a NEW FIND at Berilo Branco, Brazil. The translucent smoky is also nicely accented by the white albite on the base. The smoky is pristine, the back is sharply contacted, but is not damaged, per se. Berilo Branco produced the world famous "Van Allen Belt" rose quartz crystal specimen in the Smithsonian.
12.2 x 7.4 x 6.0 cm. We have had a couple of these Arizona classics in the auctions lately, from completely different collections. They have always been favorites - robins-egg blue chrysocolla covered with a coating of sugary, sparkly quartz. And, they have never been available in quantity, so they get good money on the market. This is a large and very impressive one! The label that came with it is from dealer Claude Humber, and indicates that he collected it himself at the mine in 1975.
6.8 x 4.1 x 3.4 cm. They called this mine the Blue Phantom for good reason. Inside this incredibly gemmy, glassy crystal - razor-sharp everywhere - is a phantom that you can clearly see due to the manganese inclusions. An interesting and super-quality quartz!
6.4 x 4.0 x 3.7 cm. This combo is now very well-known from Tongbei. Here you have gemmy smokies poking up from a bed of equally gemmy, red-orange spessartine garnets.
5.6 x 2.9 x 1.8 cm. A crystal of smoky quartz from the Swiss Alps that demonstrates why these are regarded as the best in the world, along with some select Russian ones. Super gemmy and glassy. It has an area of natural etching with tiny microfaces. Ex. Steve Smale collection and thus in superb condition and of high quality.
11.4 x 8.2 x 4.4 cm. The photos capture pretty well the incredible beauty and drama of this very unusual Erongo combo specimen. It is notable both as a plate of gemmy smoky quartz crystals, some of them on their side and showing terminations at both ends (!); but also for this sensational schorl crystal, with its mirror-like black faces. The schorl measures 3 cm. As you are probably aware, this is a very unusual Erongo specimen, and just plain beautiful.
14.3 x 11.0 x 5.0 cm. Is this not just an incredibly beautiful mineral specimen? Not only that, it is quite uncommon. Amethyst has pseudomorphed a row of frosty calcite crystals in the center. Contrasting with these is a bed of darker, gemmy prisms that surround the pseudomorphs. This specimen has size, beauty and the interest of the pseudomorphs - a lot going for one specimen!
10.9 x 8.4 x 4.4 cm. A BIG, FAT quartz crystal, in superb condition, richly shot through with hundreds of tiny needles of glowing, golden rutile! The quartz is very gemmy and has a fine glassy luster, and the faces are razor-sharp.
10.9 x 4.6 x 3.9 cm. Mostly what you see from the finds of this combo at Tongbei are plates of smaller smokies with spessartines. This is a single LARGE and quite fine crystal, very slightly smoky, with spessartines wrapping around the sides, but leaving a pretty tiered "window" (this compound crystal has a natural "ledge" to it) into the interior.
8.4 x 3.6 x 3.4 cm. A large, sharp, gorgeous Brandberg amethyst that shows amply why these crystals are so prized. The top 3 cm is gemmy and clear as glass, rising to a perfect termination. The bottom portion has this beautiful blush of bright purple, MUCH more vivid in person under good light. There is a natural contact on the back side that does not detract at all from the display side. Fine luster everywhere - a beautiful crystal!
9.5 x 2.9 x 2.6 cm. Another good Tongbei single crystal of this now familiar combo, in a different size from the other in this set of auctions: longer and more slender. This is a smoky crystal with silky luster, wrapped all the way around with bright, gemmy spessartines. No contacts or damage!
17.9 x 13.4 x 10.4 cm. A BIG, SHOWY specimen from India - a crystal-covered ridge in a pocket that was amazingly trimmed out so that it is exposed and beautiful on three of the four sides! It has so much going for it: These BIG salmon-colored heulandite bowties, smaller, pearly crystals of stilbite, and all on a backdrop of dove-grey quartz. That large bowtie in the middle measures just under 9 cm across!
9.8 x 7.4 x 3.9 cm. These galenas are dramatically isolated in a cluster of beautiful quartz, with the distinctive silky look you sometimes see in these Bulgarian quartzes. There is minor chalcopyrite here as well. As you can see a truly elegant specimen.
