A verdant hillside of lustrous, rich green mimetite is surmounted by a few elongated, lustrous and translucent, amber-colored wulfenite crystals to 1.5 cm in length. A surprising (until this find) and unique combination! All of this is underlain by a knobby limonite matrix which pokes out on the edges (and is sawn to reduce mass, in back). The contrast and balance on the specimen is very aesthetic, and it is more 3-dimensional in person.
A bubbly crust of spherical, lustrous mimetite, to .6 cm across, is particularly sparkling on this specimen for some reason. It is a beautiful, large plate with top color! The mimetite occurs as a crust and is emplaced on a limonite matrix with a sawn base. A few, sparkling, tiny wulfenites and one larger crystal measuring 1.0 cm in length, are perched on the mimetite and provide a nice accent in the corner (though the wulfenite has slight edge wear and is not value-added on this specimen at the price, per se). Small white flecks are very trivial little dings, shown in the photo more than in person. Overall, it really is one of the more beautiful large pieces, and stands out in quality for color and luster, and just leaps out at you from a case.
This specimen is higlighted by several vugs hosting the thin crusts of lustrous, rich green , spherical mimetite balls. Glassy and translucent, amber-colored wulfenite crystals, to .2 cm in length, are clustered as accents around some of the vugs. Aesthetic and sculptural, this is an excellent example of the new green mimetites.
My god, the COLOR on these mimetite crystals is crazy good...just a fiery red, the best I have seen of this material for color. They are smallish at 6-7mm, but the "Three Amigos" make quite an impact visually as they sit on this contrasting matrix, Superb specimen for quality, and a neat label as well.
An excellent representative specimen with good finger striucture and coverage, and with only some small damages, and hence very cheap for this amount of PG! However, its also clearly a pseudomorph with complete alteration from mimetite as the weight/heft is exceedingly light. The color in teh closeup is accurate, more so than the full shot.
This is my favorite of the lot, in some ways, because of its uniqueness. The PG has COMPLETELY replaced mimetite, and so the piece is very lightweight. Also, there look to be pseudos after another mineral, platy, perhaps calcite or cerussite. Overall, a superb aesthetic specimen, and very rich and attractive.
A REMARKABLE, aesthetic and old-time Tsumeb pseudomorph featuring a splaying cluster of green bayldonite after very long, thin mimetite crystals. The pseudos reach about an inch. Classic, upper level material from Tsumeb's early years prior to WWI : These are thought to have been mined prior to the 1920s. Aesthetic examples are today VERY RARE AND HARD TO OBTAIN , but in any case are also attractive pseudos aside from the historical value! This is a competition-worthy miniature. Interestingly, I am told that many of these when analysed turn out to be the much rarer species, ARSENTSUMEBITE, which would be a bonus. I have not tested this one, and most specimens carry the Bayldonite label as historically they have done, but due to the dark color here, I rate the chance highly this is, indeed, arsentsumebite.

A most unusual mimetite specimen!!! Limonite acts as the matrix for discrete rosettes comprised of spheres of lustrous, translucent, light- green mimetite. The largest rosette is 1.0 cm across. The proper display side does have a small cleaved sphere in the upper right hand corner, but the overall effect of this specimen is not compromised and it is in good shape all around, otherwise. This is one of the best examples of this very rare occurrence , found just once despite 40 years of mining for specimens here.

This is an extremely 3-dimensional specimen of the classic and very rare material found just sporadically at the Roughton Gill Mine, and of this quality & combination only in the higher levels around the 1830s (as reported in Minerals of the English Lake District: Caldbeck Fells by Cooper and Stanley. Today, they remain one of the nearly unobtainable classics for the era, especially in any kind of large and aesthetic specimen - of which this is both! It was sold at one time by the well known English dealer Francis Butler in London, in 1884-1887, according to the Min Record Labels archive (see link). Regardless of the history, it is a superb display specimen, a combination where both species are balanced and attractive, and probably worth quite a bit more in the munich show market than anywhere else, from prices I have seen in Europe on such examples in the past.

Fat, chunky crystals of cerussite have here been replaced completely with mimetite, in this rare form of pseudomorph from Tsumeb. This is an unusually aesthetic example, complete all around and very 3-dimensional!

A limonite matrix is host to tabular, lustrous and translucent, orangey-caramel crystals of wulfenite, to 1.6 cm across. Contrasting dramatically with the wulfenites are botryoids of apple green mimetite, to .7 cm across. The major crystal is intact, though some secondary crystals are admittedly damaged. Nevertheless, An appealing old combo specimen from Mina Ojuela - this is a VERY rare combo, found jsut a few times in the past. This particular pocket, with large crystals and stark contrast, was noted from the early 1980s..

Santa Eulalia is the poor stepchild in most people's minds to the commonly seen , more yellow-orange mimetite from the San Pedro Correlitos locality. However, this is only because the good old stuff from here is so rare, and uncommon. This is one of the best I know of, from older finds here (1970s?), and is a solid specimen of splayed, mushroom-shaped rosettes. The crystals are lustrous, slightly translucent, orange-amber colored , really quite unique from the rounded material out of the more common locale (SPC). And for importance, there were a LOT fewer pieces like this found at this locale, so it ranks higher than any comparably sized piece fomr the Ojuela or Correlitos locales in Mexico - and again, has a different look in any case.The largest rosette measures 2.0 cm across. On the back side are a few rhombs of lustrous, white calcite, to 1.0 cm across. This is a VERY significant mimetite from Santa Eulalia worthy of any collection. It was formerly in the collection of Marc Weill, until an exchange to me in 2007. NOTE: NOT Romero collection, but it fit well with the update and so is included here. Comes with custom lucite base already made for the specimen.

Lovely specimen consisting of numerous .6 cm crystals of Mimetite arranged in radial sprays. All the crystals have a very nice yellow color and absolutely superb luster. Naturally, the centers of sprays are contacted by their very nature. This is very aesthetic, and has to be seen to be really appreciated! It is possibly a pseudomorph after a rotund cerussite twin, as this habit of mimetite is associated with that well-known replacement at Tsumeb. Purchased from the Zweibels in 1976

This complete pseudomorph of Tennantite after Azurite not only maintains the original shape, but it is also coated with small crystals of malachite, Dolomite, and Mimetite for sparkling accents. This is a very rare and unusual occurance! It is also an extremely attractive example of this type. Purchased from the Zweibels in 1978
