4JB6 - Galena with oriented Chalcopyrite (floater!) - $ 95 SOLD Milliken Mine, Reynolds Co., Missouri, USA miniature, 3.5 x 3.6 x 3.5 cm
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!
CKTSR-10 - MAGNETITE in Chalcopyrite - $ 1500 SOLD Aggenys Mine, Kalahari Manganese Field, Northern Cape Province, South Africa small cabinet, 7 x 6 x 4 cm ex. Charlie Key
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.
CORN09 - Chalcopyrite and Quartz - $ 450 SOLD Herodsfoot Mine, Cornwall, England small cabinet, 6.6 x 5.9 x 5.2 cm
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!
den07-07 - Galena (skeletal) with Chalcopyrite on Sphalerite - $ 200 SOLD 19th of September Mine, Madan, Rhodope Mtns., Bulgaria miniature, 3.8 x 2.9 x 1.3 cm
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. ".
den07-10 - Galena (skeletal) with Chalcopyrite on Sphalerite - $ 450 SOLD 19th of September Mine, Madan, Rhodope Mtns., Bulgaria miniature, 5.0 x 4.3 x 3.1 cm
An exquisite cluster of all-hoppered galenas to 1.2cm, which reminds me of old Anasazi cliff-cities I have seen in photos.
GALS-03 - Galena (skeletal)on Chalcopyrite - $ 350 SOLD 9th of September Mine, Madan, Rhodope Mtns., Bulgaria miniature, 5.5 x 3.0 x 2.8 cm
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!
GHA7 - Siderite with Chalcopyrite (huge xls!) - $ 4000 SOLD Panasqueira, Portugal cabinet, 19 x 11 x 7.5 cm
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!
HBRU-07 - Rhodochrosite, Quartz, Chalcopyrite - $ 12500 SOLD Octahedron Pocket, Mini King Raise, Sweet Home Mine, Alma, Colorado, USA miniature, 5.2 x 4.2 x 2.3 cm 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.
HECK-008 - Chalcopyrite on Quartz with Calcite - $ 200 Concepcion del Oro, Zacatecas, Mexico cabinet, 11.4 x 7.9 x 6.4 cm 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!
HECK-042 - Chalcopyrite - $ 300 Concepcion del Oro, Zacatecas, Mexico miniature, 3.1 x 2.4 x 1.4 cm 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.
HECK-106 - Quartz & Chalcopyrite - $ 400 SOLD San Martin Mine, Zacatecas, Mexico cabinet, 10.6 x 8.4 x 4.5 cm ex. Richard Heck
The highlight of this specimen is the unusual, tapering tessin-style, 9.5 cm-tall , lustrous and translucent quartz crystal with chlorite inclusions. The inclusions color it a grayish green . The rest of the specimen is composed of a druse of calcite and several, splendent, brassy yellow crystals of chalcopyrite. An unusual combo for the locality
HECK-208 - Chalcopyrite - $ 2000 Mina Maria, Cananea, Sonora, Mexico cabinet, 11.9 x 9.1 x 6.7 cm ex. Richard Heck
This solid mass of splendent, brassy yellow chalcopyrite crystals, to 1.5 cm across, is associated with drusy, white calcite. This is a very dramatic and sparkling specimen with incredibly bright luster and incredibly brassy, metallic crystals. It is much better in person, even, and just dazzles in a showcase with light on it.
HECK-216 - Calcite with Galena & Chalcopyrite - $ 1500 Naica, Chihuahua, Mexico cabinet, 13.8 x 8.2 x 7.2 cm ex. Richard Heck
A gorgeous specimen of unusually large rhombohedral calcite festooned with sparkles! The ivory colored, large rhombohedrons fluoresce a light orange color, and are encrusted with splendent and bright crystals of galena, to 5 mm across. Bright, metallic, brassy yellow chalcopyrite crystals, to 6 mm across, are scattered about on the galena for accent. Overall a very unusual specimen with lots of eye appeal, yet a simple form overall.
J11T-170 - Chalcopyrite on Pyrite - $ 2400 Recuerdo Vein, Huanzala Mine, Huallanca District, Dos de Mayo Province, Huanuco Department, Peru miniature, 4.7 x 3.9 x 3.5 cm
I love chalcopyrites, a species that I think many people really just ignore sometimes. But this superb, competition-level miniature, is hard to put out of mind once you see it. It is the most mesmerizing example in its size class I have seen for a chalcopyrite, and just glows with color and brilliant lustre. It is as close to pristine as you can ask, especially in a soft species. Probably from older finds in the 1980s or early 90s, as I have simply not seen anything approaching this quality in recent production here. The piece is complete all around, with the crystals perched on and hanging over a thin shard of glittery matrix, covered with minute sparkling pyrite crystals. This is a competition-level miniature worthy of any major collection, despite its "common species."
JMIX08-06 - Chalcopyrite, Sphalerite, Galena - $ 350 SOLD Huaron Mine, San Jose de Huayllay District, Pasco Dept, Peru miniature, 4.3 x 3.2 x 1.8 cm
A beautifully balanced combo specimen from Peru, combining sharp, brassy chalcopyrite with stacked cubes of silvery galena and dark, lustrous sphalerite. You can see a galena cube buried right in the middle of the chalco! Stark contrast of form and color makes this a chice miniature standing out amidst the crowd from these mines.
