Ace of Diamonds Mine, Middleville, Herkimer County, New York, USA
Small Cabinet, 9.0 x 8.5 x 3.3 cm
This is a particularly aesthetic cluster of herk's, with real elegance to it instead of the "jumbliness" we so often get in larger chain clusters of these gem crystals. For that matter, the piece has crystals of a uniform gemminess and clarity , not marred by the usual ugly duckling in the midst of most clusters of several crystals or more. Taken together, these qualities make it a very special piece. Ed loved these, and had over 15 examples in the collection, more than any other variety of quartz. All, like this one, were carefully chosen by somebody who's seen literally hundreds over the years, to be extra special. I should say that, as with generally ALL large herkimer clusters, this piece is multiply repaired (by the collectors, usually). Comes with custom base.
Morro Velho Gold Mine, Nova Lima, Minas Gerais, Brazil
Small Cabinet, 9.4 x 5.5 x 5.1 cm
Dolomite crystals of this quality are rare from any location, and these translucent blades are heavily decorated by minute crystals of iridescent pyrrhotite (and some cubanite) to make them stand out. A very 3-dimensional specimen, overall! Bladed rosettes of lustrous, translucent dolomite to 4.5 cm across, are aesthetically emplaced on a colorless, gemmy, 7.0 cm across, quartz crystal. Usually one sees gemmy green siderite with minor dolomite but this is a superb PRIMARILY-dolomite specimen from one of the world’s deepest gold mines, and a fine source for good specimens as well (though miners bring them out at risk of losing their jobs!)
Holland Tunnel, Patagonia Mts., Arizona, USA
Thumbnail, 3 x 2.7 x 2.4 cm
One set of twins is nice, two is pretty rare, but three is amazing, especially when it is the dramatic appeal you find in a large thumb! Three sets of Japan Law twins set in one tight cluster. The quartz crystals are frosted to gemmy, with an equally frosted to glassy luster. Fortunately, there are only a few dings, but they do little to detract from the specimen. Even better in person. Rare to find these so small, that a thumb can be taken out...
Sapo Mine, Goiabera, Minas Gerais, Brazil
Cabinet, 10.2 x 7.3 x 2.2 cm
At 6.5 cm, this crystal on the right is the largest single crystal that I am aware of from the find. The crystal on the left side is 4 cm tip to tip (and is not damaged...it just has an odd ingrown face at that "hole" which is not distracting in person at all. The apatites sit flat on a flat quartz shard, which is a floater, complete all around! Because of the thin nature of the piece, it is translucent to light and shows extremely well when backlit.
Sapo Mine, Goiabera, Minas Gerais, Brazil
Large Cabinet, 8.8 x 8.4 x 2.2 cm
A cascade of deeply colored crystals to 1.75 cm stands on top of this slender quartz shard! For some reason, it is these few crystals on quartz that have the best and deepest color and lustre. Better in person!
Papachacra, Belen Dept., Catamarca, Argentina
Cabinet, 10.1 x 7.8 x 6.5 cm
An original core of milky quartz was later overgrown by a dark, lustrous and translucent, intensely smoky quartz crystal measuring 9.5 cm in length. When backlit, the milky core becomes an otherworldly phantom. A nice color contrast to the smoky quartz is the associated beige colored feldspar matrix. The termination has a few, tiny, insignificant sub-mm bits of wear but i would call it "essentially pristine," and anyhow it is the largest really good smoky quartz point in this condition from this find, that I have yet obtained.
Mine El Gaudo, Talampaya, La Rioja, Argentina
Small Cabinet, 6.9 x 5.7 x 3.4 cm
A thin septa of sparkling, colorless, quartz druse has allowed crystals of frosted, translucent, sea foam green, fluorite octahedrons, to form above and below the plate. Very 3-dimensional!!! . Average crystal size is 1.0 cm across but the cluster atop is about 3 cm. Under fluorescent light, the fluorite is an intense, neon purple. Very aesthetic specimen, elegant, and rich with this new fluorite.
Ortega Prospect, Northern Ancash Dept., Peru
Small Cabinet, 8 x 6 x 4.5 cm
Quartz crystals, to 2.5 cm in length surround green crystals of augelite, to 1.5 cm. This is one of the few specimens with associated anything, let alone quartz.Large and impressive overall, it provides a fine display for a half dozen good augelite crystals
Ortega Prospect, Northern Ancash Dept., Peru
Small Cabinet, 8 x 5 x 2.5 cm
This is a showy radiating quartz specimen with 2 beautiful, gemmy green Augelite crystals to 1.5 cm in length perched atop. This is one of the few specimens with associated anything, let alone quartz. It makes for a nice display, and the isolation of the crystals is uncommon here.
Vera Cruz, Mexico
Small Cabinet, 9.6 x 6.0 x 5.0 cm
Very closely resembling a rocket, ready for liftoff, this unusual and super matrix, amethyst crystal is doubly-terminated, very lustrous, and exhibits a lovely, rich lilac color. To me the most fascinating characteristic of this amethyst is the fairly uniform hopper growth on all the pyramidal faces. Most unique. From the collection of R.F. Denicourt. This is one of the very largest speicmens I have seen of any single crystal from the locality!
Small Cabinet, 6.6 x 2.4 x 2.0 cm
A magnificent clear, gemmy quartz crystal with a dark purple phantom enhancing the interior. There are nine cute prehnite balls attached to the back which complete this 360-degree , pristine, specimen. It is so sharp, like cut, and one of my favorite single crystals in the whole offering.
Cabinet, 9.7 x 7.3 x 7.2 cm
Here is your chance to own a fabulous gem quartz with a smoky phantom. This specimen has been repaired to a sawn base, but was replaced as it originally grew. If you do not like the base it would be easy to remove the crystal and have one of the best smoky phantom singles in the collection...still worth the $300 on its own merit. But, we left it on, as Charlie did, for the overall impact.
Cabinet, 14.6 x 11.6 x 7.3 cm
A dramatic, complex, massive smoky quartz with glassy luster and a hint of amethyst on select faces of . This monster shows skeletal and hopper growth, and is much more dramatic in person. It is very 3-dimensional and complete all around!
Cabinet, 10.8 x 3.3 x 2.6 cm
Here is another large, incredibly lustrous & glassy crystal with deep smoky amethyst coloration and a small water bubble towards the top. Add this smoky phantom and you’ve got yourself a winner. It is MUCH better, more appealing in its subtle blend of colors, in person.
Miniature, 4.7 x 3.2 x 2.5 cm
This amethyst specimen from the Brandberg mountains is a great example of amethyst but a very atypical example of quartz! Note the secpters to the lef tand right, on quartz cores. Yet, the middle crystal grades elegantly into the amethyst termination WIHTOUT creating a sceptre effeect. Bizzare, on the same specimen!? In any case this is a lovely, 360 degree group of dark purple amethyst on top of milky quartz, technicalities of uniqueness aside.
Miniature, 5.6 x 4.3 x 2.9 cm
A gorgeous, 3-D, splayed matrix group of light amethystine quartz. Note that while two of the crystals are show reverse scepter form at their tips (n either edge), the core crystals in the center show normal terminations - a neat contrast!
Small Cabinet, 9.3 x 5.8 x 4.3 cm
Delicious grape color just visually leaps out of this large amethyst crystal. The color is DEEPLY saturated and the lustre is high, making this one of the outright prettiest pieces here. The photos cannot show the internal , almost-red flashes. Must see to appreciate! Truly wonderful specimen of no fancy habit (actually unusual for this locale!) , but complete all around and eye-appealing
Cabinet, 11.6 x 6.5 x 4.8 cm
Very large, extremely interesting smoky/amethyst quartz crystal with a very deep skeletal termination showing 5 deep holow clefts into the core of the crystal. A major specimen from the Gobobos, for this rare habit. Complete all around the termination, though incomplete on the bottom and lower rear.
Small Cabinet, 7.7 x 3.0 x 2.3 cm
A beautiful, gemmy, clear quartz crystal with amethyst and smoky phantoms. This crystal has a lovely sharp termination and rainbow effects galore. In person, it is very dramatic and leaps out!
Cabinet, 9.4 x 3.8 x 2.5 cm
A large smoky/amethystine, enhydro, scepter ! This crystal has stunning lustre. It is a perfect, gemmy crystal with an obvious enclosed (enhydro) water bubble crossing the main face of the crystal. Wonderful eye appeal.
Zinnwald, Bohemia, Czech Republic
Miniature, 5.5 x 4.0 x 1.7 cm
The scheelite is exceptional for Zinnwald ...this is CLASSIC old scheelite from a classic locality, with crystals to 9mm, perched on a terminated quartz shard. This is very beautiful and aesthetic!. ex. American Museum of Natural History and shows a Bement collection numbering on the bottom, along with the "arrow" that the AMNH curator Gratacap used to show alignment of specimens on a display shelf. This indicates the piece was on display after the donation of the Bement collection around 1910, by JP Morgan
Telírio claim, Linópolis, Divino das Laranjeiras, Doce valley, Minas Gerais, Southeast Region, Brazil
Cabinet, 11.2 x 9.5 x 7.8 cm
A most unusual specimen with a 2.5-cm brazilianite crossing the termination of a gorgeous, jewel-like quartz crystal , totally water-clear and perched in albite matrix. The quartz measures about 8 cm tall and its termination is freestanding save for the crossing brazilianite atop. VERY dramatic and unusual specimen!
