7.2 x 4.9 x 4.9 cm. The pic just has to speak for this specimen by itself, because it would be difficult to describe the truly astounding and unique crystallography of this Missouri galena. There are two intergrown habits of crystal here. One of them is a fairly conventional cube with a stepped form on the back side. The other is just incredible; it is roughly a rectangular shape overall, but the surface consists entirely of every conceivable modification of the cubic form, as if it were created for a science class! Spinel twinning is abundant here as well. Ex. Feist Collection.
10.4 x 9.9 x 5.5 cm. A big, rich specimen of galena from the older mining there, not the recent finds. This is a dense cluster of very sharp crystals with a high metallic luster, both octahedrons and cuboctahedrons. There are a couple of areas of wear, but overall it is in very good shape. The crystals are all around this specimen - the matrix in the middle was covered on all sides and all the way around!
11.4 x 8.4 x 7.8 cm. What makes this big galena crystal so distinctive is that a corrosive solution flowed through the pocket some time after its formation, etching the crystal into these complex stepped forms. It is beautifully isolated on a matrix that sparkles with little golden chalcopyrites -a fine natural "base" for this very unusual crystal. The galena measures over 4 cm along the edge.
6.5 x 6.4 x 5.9 cm. Because the lusters are so similar, it is hard to distinguish in the pics here where the galena ends and the sphalerite begins. But in general, the galena has formed between the sphalerite crystals with strange smooth, curved faces, and as you can see, the sphalerites have these intricately stepped/tiered faces, with a shiny black luster. There is very little matrix here - this is almost all intergrown galena and sphalerite.
12.5 x 11.2 x 4.9 cm. I think you can see from the photo how wonderfully unique this LARGE Eastern European combo specimen out of the Wein Collection is. This is largely due to the extremely unusual rounded faces of the galena crystals - not to be confused with non-crystallized, massive galena - the faces are just super-modified and shallow. On them sit crystals of brassy chalcopyrite, and here and there, sphalerites - which stand out against this backdrop of silky silver galena. Ex. Wein Collection (Stuttgart).
5.0 x 4.2 x 2.9 cm. This is a fine old Tri-State galena, a compound crystal consisting of three interlocking subcrystals, in an architectural, stepped arrangement. The luster is brighter in person. A simple, elegant, sculptural specimen.
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.
6.4 x 5.9 x 4.7 cm. What a beautiful Eastern European galena this is! For one thing, the luster is just fantastic, what I like to call "mirror-metallic." But just as impressive is the architectural, stepped structure. Some of these crystals even have very thin, platy tiers on their faces that add to the interest. Minor quartz and pyrite associations. Nice!
7.9 x 4.5 x 2.5 cm. A sharp spinel twinned galena stands up dramatically in the midst of a cluster of quartz crystals with an orange color from a later generation of small calcites. I like how the spinel twin is isolated and showcased on this impressive Eastern European specimen.
5.5 x 4.9 x 4.5 cm. As you can see, this compound galena crystal from Bulgaria has the most incredible architectural form! It is ornately stepped all around, and you can display it from almost any direction - it is a floater, with no ugly contacts! The specimen has a fine mirror-metallic luster as well.
1.0 x 2.9 x 2.4 cm. A beautiful spinel-twinned galena specimen, this one, without matrix. You can see the complex and pretty epitaxial growth on the crystal faces in the pic. Those are little quartz crystals growing off of the galena. This fine twin is lustrous and well-formed on BOTH sides.
8.6 x 5.4 x 4.9 cm. This specimen shows the galena spinel-twins in their more chunky form (as opposed to the flattish form the other exemplifies). These crystals (to 2.4 cm) have a fine luster and are razor-sharp.
8.2 x 6.9 x 5.5 cm. I like to call this sort of luster "mirror-metallic" - it is just fantastic. These crystals, to 1.8 cm, also have all sorts of interesting growth modifications - hoppering, skeletal growth and corner bevels amongst them. You can see some accenting quartz crystals in between the galenas here and there. A fine Eastern Euro galena!
8.9 x 6.4 x 4.0 cm. Here you have two galena crystals, the larger of them (2.5 cm) showing an incredibly ornate surface, with modified octahedrons all over the underlying cube. Near it, the smaller crystal has formed similar modifications, though not in the same quantity. Really unique and cool old tri state material from the old Tri-State District.
4.8 x 4.1 x 3.3 cm. A complete, complex and beautiful spinel-twinned galena from Eastern Europe, standing beautifully on its side, accented with gemmy quartz crystals. This galena twin is complete on both sides and edges. If you look closely you can see complicated hoppering and wave-like tiers on some of the faces. Wonderful example of this twinning phenomenon in galena!
