Modified cubes of Galena are always nice, but the stacked cubic growth, generously sprinkled with abundant chalcopyrites on faces to one side, makes this specimen an attractive and unique oddity. Also, it is a floater, complete all around!
Perched aesthetically high on its matrix is a lustrous and translucent, pastel-green fluorite octahedron, measuring 3.6 cm in length. It exhibits complex details of secondary growth. Directly under the fluorite crystal are two lustrous, milky quartz crystals, to 1.5 cm in length, which ultimately give way to bright, brassy yellow chalcopyrite crystals underneath . The chalcopyrites reach to 2 cm on a side. This looks for all the world like a classic combo piece from Naica in Mexico, from the 1970s-1980s. Collected 2006-4-10th, and from a prominent and carefully assembled collection of Jiangxi minerals with precise localities.
An aesthetic combo piece featuring a cluster of lustrous and translucent, pastel-green fluorite cubes, to 2.5 cm across, perched aesthetically on a lustrous, translucent, and colorless quartz crystal. Additionally, there are a couple of brasssy yellow chalcopyrite crystals, to 1.3 cm across. A very unusual Chinese piece that looks like classic old Mexican material from Naica, at first glance! Collected 2004-12-16th, and from a prominent and carefully assembled collection of Jiangxi minerals with precise localities.
A deep green fluorite crystal cluster is perched on a thick crust of terminated milky quartz crystals. Between them is a layer of brassy yellow chalcopyrite crystals, to 9 mm across. The fluorite crystals , to 3 cm, exhibit both pastel green and rich green colors that intermingle for a nice visual effect. The fluorite crystals also exhibit classic stepped growth, for interest. BETTER IN PERSON, this ia a VERY rich green evergreen color. Collected 2005-5-16th, and from a prominent and carefully assembled collection of Jiangxi minerals with precise localities.
Several crystals combine to form this really beautiful cluster of solid chalcopyrite. It is nearly a floater all around, with just some minor contact and a few small bits of damage only. It looks like a solid mass of chacopyrite topped by two lustrous brassy yellow crystals, to 3 cm in length, although those crystals help compose the actual matrix itself as well. This is a very choice chalcopyrite from China, in quality resembling the best of Peruvian material. It is robust, and has excellent color. The detail is very complex, wtih small striations throughout. Collected 2005-12-10th, and from a prominent and carefully assembled collection of Jiangxi minerals with precise localities.
This is a rare tetrahedrite from China, from a new find apparently. It has sharp, textbook crystals to over an inch, some coated on oriented faces by incredibly metallic, bright chalcopyrite in a micro-thin layer. It looks like the tetrahedrite crystals were dipped in gold plate, on those faces. Small calcites are also attached for texture.The piece is nearly complete all around, with just a small contact area on bottom. Although a fine specimen in its own right, I bought this in part because it was a freak piece , to my eyes, just a single nice specimen from "a new mine" in the rich Nan Dan area where so many calcites have come from. Time will tell whether more come, or none...

Who knew?! I had never hear dof anything from this mine except a few strangely formed rhodos, til Charlie's Collection surfaced. He has a whole suite of weird sulfide combinations from this locality, for example this one featuring SHARP alpine-quality magnetite in contrasting chalcopyrite matrix. The largest magnetite is 2 cm across! This is the best matrix specimen out of the whole lot of about 2 flats, which he had acucmulated over the years from a worker at the mine.
Sharp, golden, 2-cm crystals in a spray perched atop a knoll of quartz! This is old classic material, from the heyday of the Herodsfoot Mine!
A sharp 9mm cube, hoppered throughout, perched on chalcopyrite! As my friend John Veevaert found out and reported in his show report elsewhere, "it was mentioned to me that these were actually found about 20 years ago and ignored until someone in Bulgaria figured out how to remove the encasing clay without damaging the delicate features of these remarkable specimens. They are just absolutely incredible and easily the most impressive new thing here at the show. ".
An exquisite cluster of all-hoppered galenas to 1.2cm, which reminds me of old Anasazi cliff-cities I have seen in photos.
A massive chalcopyrite matrix sporting brassy yellow crystals to 1.5 cm in length is the host for a small cluster of etched, skeletal, battleship-gray, crystals of galena. The rear-right side of the matrix was sawed to remove it fro mthe pocket, though this faces the back. These crystals, which reach 1.5 cm in length, are so eaten away, that only the crystal edges remain and are slightly twisted as if caught in a storm. Superb example of this rare habit!
A monstrous specimen with the largest chalcopyrites I have yet seen from teh locality. Perched upon them are disc-shaped, lustrous brown siderite crystals and spiking out from the chalcos are several fine quartz points. An EXCEPTIONALLY LARGE specimen for the locality and in remarkably good shape! What is more, it displays nicely despite its size. Somebody took a lot of care getting it out!
ex. Helmut Bruckner
An incredible miniature, simply stunning, with crystals so gemmy and transPARENT, they look carved and glued on to the tetrahedrite. The matrix is crystallized tetrahedriteof jet black color an dlustre, not the usual gray or dull style. A few clear quartzes by accent, and you have a simply stunning, top calibre miniature that would fit in any competitive case. There is simply nothing wrong with the piece...it is textbook pristine and aesthetic. Out of all the hundreds of rhodos he selected from in his day (Helmut was the rhodo agent contracted to be selling to Europe for most of the 1990s!) , this was the one Helmut kept. There are bigger, but not many finer. Rhodos of this quality do go for an admitted "arm and a leg." They must. There are just so few of them to go around.
ex. Richard Heck
This specimen features unusually flattened, lustrous and translucent calcites perched on colorless quartz crystals, to 1 cm in length. Associated with the quartz are splendent, brassy yellow crystals of chalcopyrite, to 1 cm across. The disk shaped crystals of lustrous and translucent, white calcite crystals, to 3.25 cm across, are then perched on both the quartz and chalcopyrite. Neat combo specimen!
ex. Richard Heck
Lustrous, brassy yellow, SHARP crystals of chalcopyrite clearly exhibiting a superb twinning (inverted V's) highlight this super miniature. The crystallization of the twins has merged to form a large composite crystal measuring 2.75 cm across.
