Beautiful twin with superb habit and very attractive drusy surface. The crystal is so sharp that, if you follow the twinning plane down, there is an extremely attractive little triangular face right at the base of the plane. It is barely visible in the photos because of the lighting angles, but it stands out beautifully in person. Just a contact on the back and one tiny ding, otherwise perfect all over. This is quite the aesthetic thumb and incredible for the species, especially from a US locality.
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...
An exceptional specimen from old finds here, probably in the 1980s, which features huge tetrahedrite crystals to several inches on size in combination with aesthetic quartz crystals. The specimen is in very good shape, nearly pristine and complete most of the way around the back even. It is a piece of high significance, I would say, for both the lcoality and the species. Most that you see fomr here are either smaller crystals of no significance or , in some occasions still today, large crystals to this size and more but very flattenned. I rarely see any with such 3-dimensional geometric form, much less in association with these great quartz crystals which really covnert the piece from "just" an important tetrahedrite into a display specimen on another level entirely to my eye. Ex. Francis Allegra collection.
For the size and overall visual impact, this is a stunning and unusually large rhodo plate with SHARP, and I mean SHARP, GEMMY crystals to 2 cm in size. Most of them average 1 cm. Sprinkled amonst the red, are sharp black clusters of metallic tetrahedrite which make for a really nice contrast. The overall shape of the piece is very sculptural with a slight curvature to it, not "cookiecutter" or blocky as so many large specimens are trimmed out from the plates they are sawed out on. The piece has the TOP CHERRY COLOR. This is not off-color, not strawberry in hue as so many you see on the market today are. This is a piece that has the color and lustre combination (important!) that, even "way back when" only a few years ago when the mine was still open, even in context of the many finds after 2001 or so before it closed, you couldnt get. Most people then and now settle for pieces with lesser color saturation, less lustre, and more damage...its all that is out there. I sold this one back in the late 90s and was happy to get it back recently! You just cannot find large cabinet rhodos of quality around. And this is one I am happy to have owned again and again, and would do so a third time. They appreciate at such a fast clip every year, 20% or so it seems, that I cannot replace my supply except by buying entire collections with specimens in them. So, I rarely sell mine. Or, as with this one, I'll give it a few months on the web and then pull it down and stash it for the future. Just cashflow...this is one rock I am happy to keep as rhodo today is "red gold" in the bank better than the cash is. Comes with custom lucite base for easy display. Recently, I had the chance to trade this older specimen back from a collector and i STILL find it unique, now, 3 years after I first had it.

This attractive plate features the sharp lines of superbly crystallized, large, very lustrous, tetrahedrites, to 3.25 cm in length. These crystals visibly have complicated striations that give them a lot of character and dimensionality, plus they stand out more from the matrix than you normally see in Mexican tetrahedrites. In fact, the quality is so good here, they are of a quality you associate with Peru (but the overall look is distinct). This is certainly one of the best examples we have seen, for quality. . . there are bigger crystals to be sure, but this association on sparkly pyrite, with dramatic individualized crystals, makes the piece.

This specimen has a metallic golden brightness to it that looks manmade, brighter and more metallic even than modern Peruvian material can be. It is an old specimen from the collection of the late Dr. Richard Heck. Displayed one way, there is a large twin to the left, and the piece balances standing up like a triangle. Or on its side, the large , complex chalcopyrite twin graces the bottom, and smaller crystals rise above it to form a pagoda of sharp, golden-brassy color. So bright is it, that it leaps out of a case as the most metallic mineral in the Heck collection, amongst sphalerites, pyrites, and other species. It is just vividly colorful and brilliantly lustrous. One of the highlights of this fine old Mexican mineral collection. Joe Budd photos.
A SHARP, and unusually equant crystal to 1.6 cm on edge, of this rare variety of tetrahedrite that for a long time was thought a separate species because of its high mercury content. It certainly dates to AT LEAST the 1800s, if not earlier when this mining region was more active. This also came through Schwethelm, though his number came off in cleaning. Nicely perched on a well-trimmed massive barite matrix of snowy-white!
14.5 x 8.5 x 5.0 cm. A showy, old-time CABINET specimen of lustrous, battleship-gray tetrahedrite tetrahedrons richly covering drusy quartz-covered matrix from St. Andreasberg, Germany. Classic material from a classic locality.
8.5 x 7.0 x 4.8 cm. A showy and excellent combination piece from the 1992 Museum Pocket at the famous and now-closed Sweet Home Mine of large tetrahedrite crystals to 3.5 cm attractively covered with and surrounded by clear to frosted, light blue fluorite cubes and needle quartz crystals on sulfide matrix. This is the pocket that produced the famous large diorama exhibit in the Denver Museum of Natural History.
18.9 x 9.2 x 5.3 cm. A large and extremely rich specimen of tetrahedrite from the famous Hedgehog Pocket at the Sweet Home! This specimen is notable for the beautiful separation between the tetrahedrites (which measure to about 1.3 cm) nestled in a field of sharp, translucent-to-transparent quartz crystals. On the underside of the specimen are a few little patches of massive pink rhodochrosite, marking its origin.
5.5 x 3.1 x 2.1 cm. A one-cm rhomb of gemmy rhodochrosite, with nice deep pink color and fine luster, nestled in the side of a pocket with slender crystals of quartz and dark tetrahedrites. Sweet Home rhodos have become ridiculously hard to get!
14.4 x 10.7 x 5.5 cm. This is one of the finest Peruvian Tetrahedrite specimens that I have come across. This large cabinet is populated with dozens of razor-sharp complex tetrahedrons that have superb luster. Many are 1 cm on edge! With such contrast between the Tetrahedrite and the Galena, none of the pics do the piece justice. In person, it is a killer. Ex. Charlie Key stock.
5.6 x 5.2 x 1.7 cm. An outstanding specimen from the world's greatest Rhodo locality, the Sweet Home mine. This Hedgehog Pocket piece features a lovely 2 cm! reddish pink rhomb that has excellent luster, is virtually pristine from the front (and is naturally contacted along the back, and we are lucky to have it at all from the extremely difficult mining) and sits on a bed of Quartz crystals and matrix. Below the main crystal is a ribbon of beautiful smaller Rhodochrosite rhombs, several of which a partially gemmy. Good quality Sweet Home pieces are getting harder and harder to come by. This is a gem in its own right. Very aesthetic.
15.9 x 11.9 x 5.9 cm. A BIG, RICH specimen of whopper tetrahedrites from Peru! These crystals, some with a thin coating of brassy chalcopyrite, measure to 2.5 cm along the edge. There is a bit of damage to a few corners, but very modest. In the crook of the specimen is a cluster of quartz crystals that have grown on a patch of sphalerite, which is intergrown with the tetrahedrites.
10.9 x 10.5 x 9.4 cm. A very large combo specimen featuring an incredibly impressive row of HUGE, complete and terminated crystals of hubnerite, on the edge of a cluster of massive and crystallized tetrahedrite. These hubnerites measure up to 7 cm! They have sharp, angular terminations, all perfectly intact! The crystals are actually a gemmy, very deep red - but as with all hubnerites of this size, you can only see this if you hold them up under a very strong light source. This is an old-timer, and just an incredibly impressive example for the hubnerite species; the association with the tetrahedrite adds an extra punch.
