OK, we have all seen a number of galenas from the missouri mines, but even so folks, this is a particularly dramatic piece with great aesthetics! The cluster of galenas is displayed so nicely on this natural pedestal, its hard to believe its natural! A very showy, large, display specimen! 13.8 x 11.0 x 6.1 cm
8.2 x 6.5 x 4.2 cm. The crystals on this superb Eastern European galena, from a collection we have been trickling out, are just so terrific and sharp in form. Some of them interlock. Others show tabular form, and modifications toward the cuboctahedron. The surfaces have a beautiful, silky "brushed-steel" appearance.
Bizarre, elongated, pointy, hoppered galena crystals to 2 cm are perched here in a cluster on contrasting bronze/iridescent chalcopyrite, making for a stunning contrast! It is very 3-dimensional in person and looks like a robot, to me. The galena is not just metallic. It has a thin surface alteration of iridescence and flashes brightly, more than you would expect. Something about it is just DIFFERENT, is all I can say, and it really shows off in a case. 9.5 x 6.5 x 4.2 cm
4.7 x 3.8 x 2.2 cm. A lustrous, sharp, 1.3 cm, complex galena crystal nicely set on glassy quartz crystal matrix from Neudorf, Germany. This is CLASSIC, OLD-TIME material from a renowned location. This specimen is easily over 100 years old. Ex Joseph Rawlings and Seaman Museum Collections. Rawlings was born in 1826 and worked as engineer at the Cliff and Minnesota Mines. The Cliff closed in 1883!
4.8 x 4.3 x 3.7 cm. Just a GREAT-looking galena from the prolific Madan district - these crystals are so sharp and well-formed, and have the best shiny-metallic luster. They are accented with some creamy calcite, and sit on a large chalcopyrite crystal, which creates a nice contrasting natural base for the galenas.
15.4 x 12.7 x 6.9 cm. A large cabinet specimen combining 3 classic Denton Mine minerals: a large, complete, euhedral calcite crystal; cubes of galena; and deep red, lustrous sphalerite crystals! Ex Ed David specimen. This remarkable combo is from a famous 1987 pocket called the Butterknife Pod and is well documented.
8.2 x 5.1 x 2.8 cm. This is just a fabulous Dalnegorsk galena specimen, for two reasons: one, the spinel-twinning is so wonderfully exaggerated here in these sharp, shiny flat hexagonal crystals. But secondly, it is decorated with sharp sphalerites that are as lustrous as glass. So you have the beautiful sphalerites dominating the left side of the specimen, and the twinned galenas starring on the right.
11.9 x 10.4 x 2.7 cm. Shiny-metallic crystals of galena to 2.5 cm, on a bed of quartz crystals, with little golden chalcopyrites sprinkled here and there. Note the very interesting modifications on the isometric habit, with beveled corners, and even a triangular crystal!
12.6 x 10.4 x 4.9 cm. An impressive 3.8-cm galena cube is perched at the edge of a matrix covered with sparkling, deep red crystals of sphalerite. A smaller galena sits opposite it on the matrix. A sizeable specimen of a classic tri-state combo!
9.1 x 8.7 x 4.2 cm. The old label that accompanies this old German specimen actually lists the locality as "Beialf, Prussia", a testament to its age. It features galena crystals of gunmetal gray clustered along the center of the matrix, in a shallow depression. Ex. Seaman Museum.
28 x 19 x 5.5 cm. Outrageously good museum-sized plate of light grayish-purple 2 cm cubes of Fluorite. The cubes (there must be over 60 of them!) have excellent luster and the classic superb fluorescence for which the term actually was derived. Yes, the effect of fluorescence was defined based on glowing fluorite from this locality! To raise the bar even more, there are well-formed Galenas to over 5 cm which have very good luster. Greater yet, there are three generations of epitaxial growth that go quartz-galena-quartz. I have rarely seen an English Fluorite this large that matches this superb specimen for quality and interest. An amazing combination piece from one of the world's great fluorite districts. A true old-time classic from the J. Cilen Collection. Locality is almost certainly Blackdene Mine in Weardale. But, it could be one of several mines in the area that were operating over time.
4.0 x 2.6 x 2.6 cm. A STRIKING English CABINET piece of gray quartz pseudomorphing cubic fluorite crystals; and beautifully sprinkled with two steel-gray galena crystals and tiny, complex sphalerite crystals from Alston Moor. The back is covered with sphalerite crystals. CLASSIC, OLD-TIME English material of each species - but rare in such an unusual combo.
4.0 x 2.7 x 2.7 cm. Glassy, tan, cyclically-twinned cerussite crystals jauntily perched on crystallized galena matrix from the famous, old-time locality of the Mezica Mine in Slovenia. Seldom available in this quality from this mine.
12.4 x 8.4 x 4.2 cm. This is a sensational Eastern Euro combo specimen out of the Leithhauser Collection. What you have is an amazing quartz crystal with complex staggered growth and dozens of sub-terminations on its faces - and it is doubly terminated! Around the middle of the crystal is a belt of superb galena crystals to 2.8 cm across - razor-sharp and with a fine silky metallic luster. There is minor sphalerite as well.
6 x 4 x 3 cm. Attractive and very interesting combination piece consisting of modified Galena dodecahedrons intergrown with thick plates of Pyrrhotite. The Galenas, the largest of which is about 3 cm, have good luster and occasionally modified faces. In some cases, there is incomplete growth, but that doesn’t detract at all. The Pyrrhotites are an amazing .7 cm thick, and have very good luster. An important specimen from a very famous locality.
