7.6 x 5.8 x 4.8 cm. A classic and aesthetic combination specimen from the famous Mid-Continent Mine of the Tri-State District. A 6.2 cm, lustrous and translucent, frosted, golden-amber calcite scalenohedron is jauntily attached to silicified limestone matrix covered with sphalerite and a couple of sharp galena cubes. Pristine, old material from the George Feist Collection, #2824.
9.9 x 8.2 x 5.1 cm. At the center of this Eastern European specimen is a LARGE galena crystal (just under 4 cm along one edge) that shows bizarre growth modifications, including a pretty terracing on one side. Parts of other crystals peek out from under the blanket of sparkly quartz.
6.2 x 5.8 x 5.2 cm. Another pretty Eastern Euro galena specimen, this one with two main, mirror-metallic crystals in the center, both around 2 cm on edge, surrounded by smaller crystals and some quartz and pyrite. There is a little contact on the inner edges of the two big crystals.
22.5 x 15.3 x 1.2 cm. This is a large, striking slab of banded minerals from Poland we acquired from the collection of Dave Stoudt, who was stationed in Poland for a decade and was able to buy from miners and dealers during his time there. It is a slice through essentially a boulder of alternating bands of three different minerals that were laid down in successive layers, similar to the way agate gets its bands, but with an exotic mix of minerals here rather than just quartz (as with agate).
20.8 x 12.2 x 1.2 cm. A big, gorgeous and flashy specimen from Poland, a slice through essentially a boulder of alternating bands of three different minerals that were laid down in successive layers, similar to the way agate gets its bands, but with an exotic mix of minerals here rather than just quartz (as with agate). This specimen came out of the collection of Dave Stoudt, who was stationed in Poland for a decade and was able to buy from miners and dealers during his time there.
8.3 x 3.9 x 3.4 cm. Numerous SHARP crystals of matte-black, octahedral galena to 1.2 cm in length are nestled in a vug of massive galena. For a color contrast there are a few crystals of ivory colored dolomite to accent them. Octahedral crystals of galena from Tsumeb are particularly rare though for odd reasons ANY galena in crystallized form is extremely uncommon from this mine despite its overall production tonnage of galena ore. So, to get a really good galena, good enough to go with a display-quality Tsumeb collection is harder than you might at first think! Ex. Charlie Key Collection.
4.7 x 4.2 x 4.2 cm. Massive, dark gray, galena is the matrix for these crystals of lustrous, translucent, stony-beige crystals of smithsonite. The largest crystal is doubly terminated and measures a whopping 3.75 cm in length. The arrangement of smaller smithsonite crystals adjacent to the large one is quite pleasing to the eye. THIS IS A HUGE CRYSTAL for this particular habit, elongated and doubly-terminated, and thus overall quite significant. The crystal is REALLY FAT, and yet the whole thing is translucent. Ex. Charlie Key Collection.
4.9 x 4.1 x 2.9 cm. This specimen is incredibly flashy, because both the galena crystals and pyrite crystals have this mirror-metallic bright luster. There are some pretty little modified rhombohedrons of translucent calcite as an accent.
4.2 x 3.6 x 2.2 cm. This combination is best known and classic from the Commodore Mine in Colorado, but here it is in a specimen from Bulgaria! - and with a special twist - note the bizarre skeletal galena, particularly the one at the edge of the specimen where natural etching has left these two former crystal edges sticking up like arms off the specimen! Other crystals have indentations, curves and all sort of weird distortions. The sphalerites came later.
6.6 x 5.6 x 4.4 cm. A complex, architectural specimen composed solidly of galena octahedrons, classic Tri-State material.
11.0 x 10.7 x 5.1 cm. A showy, OLD-TIME CABINET specimen of melted-look, variably lustrous galena crystals richly covering the top of vuggy, massive calcite matrix invested with numerous, colorless calcite scalenohedrons on both the front and back of the piece. This is CLASSIC material from the famed St. Andreasberg District of Germany. This old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe.
6.3 x 4.8 x 4.0 cm. This is an old Naica specimen (not from the fluorite finds of around 2 years ago), and you can tell by the style. In person these crystals are MUCH brighter and more transparent than the photo makes them appear. They measure to about 1.7 cm across, and they have pretty bevels along the edges.
5.9 x 4.8 x 4.5 cm. A complex crystal of galena from the Tri-State District, out of the collection of Gene Meieran. You can see that it has a very pretty architectural structure, and a sort of "antique" looking patina rather than a shiny-metallic one. The corner bevels have what appears to be some natural corrosion.
4.4 x 3.4 x 2.7 cm. Yes, this galena crystal is really as weird in form as it looks - presumably from natural etching, leaving it with curved, melty-looking surfaces pretty much opposite the normal character of galena with its flat-faced cubes. You can see a crystal of sphalerite intergrown with it on the right side.
3.2 x 1.4 x 1.0 cm. A HISTORIC, OLD-TIME and showy specimen from the famous Galena District of Illinois. This is a very nearly pristine, slightly curved, FLOATER cluster of lustrous, intergrown galena cubes. The Galena District furnished much of the lead for the North during the American Civil War, 1861-1865. Accompanied by an old handwritten label in French. Ex. Paris Museum of Natural History and George Feist Collections.
