9.3 x 7.4 x 3.8 cm. This Tri-State galena is distinctive for the beautiful isolation of its crystals on this stark contrasting matrix, and for the interesting crystal forms. The crystals show micro-stepping on their faces, as well as some larger epitaxial faces. Also, there are many interesting modifications to the basic cubic form here - you can see cubes, octahedrons, and every sort of weird permutation in-between! Ex. Marty Zinn Collection.
8.4 x 7.8 x 4.1 cm. An old Joplin galena with crystals richly piled up on the matrix. The largest one is just under 2 cm on edge. They are very sharp, and have a nice gunmetal luster to them. Classic old material from the Tri-State mining district.
2.7 x 2.4 x 1.6 cm. Look at the fabulous luster on this cluster of super-sharp crystals (actually a compound crystal) of galena from Naica! Naica is known for its fluorites, often in association with sphalerite and galena. But you occasionally get these fine standalone galenas as well.
6.2 x 4.4 x 4.2 cm. Out of the F. John Barlow Collection (#3336) - an old Naica sphalerite with really sharp crystals, including a superb one right in the middle of the display face with gorgeous striations (actually minute stepping) in a band around the side and on the termination. These are large, euhedral crystals, not the usual shallow and rather nebulous ones. Fine luster as well!
4.5 x 3 x 2.5 cm. Two shiny-metallic, flattened spinel-twinned crystals, with sharp pyramidal form, leaning back on a matrix covered with gemmy quartz crystals. The specimen was shot from the front so you cannot see that these spinel twins are very thin and platy, with faces on both sides. A fine Eastern Euro mini!
11.9 x 8.9 x 4.8 cm. Another fine Tri-State piece - this, a large, gorgeous galena cube with four smaller ones accenting it. The big one measures 3 cm along the edge. There are some tiny ruby-jack sphalerites on the matrix as well. It is the isolation of these crystals and their attractive arrangement on the matrix that makes this specimen so showy. Ex. Feist Collection.
9.8 x 7.4 x 3.9 cm. These galenas are dramatically isolated in a cluster of beautiful quartz, with the distinctive silky look you sometimes see in these Bulgarian quartzes. There is minor chalcopyrite here as well. As you can see a truly elegant specimen.
6.1 x 4.6 x 2.6 cm. This is an old-timer from Santa Eulalia -- a matrix-free specimen of crystallized galena, with a shiny-metallic luster and extremely complex, stepped faces - with associated pyrrhotite of a dull bronze color. The altered form of both minerals indicates that there was natural etching in the pocket of both the galena and the pyrrhotite.
10.8 x 9.6 x 4.9 cm. A large and VERY impressive Naica galena, not from the recent finds of galena, fluorite and sphalerite, but from old mining at this classic locality. There are dozens of wonderfully-formed, shiny crystals here, sharp as can be - attractively isolated by a sparing amount of matrix. There are all sorts of variations on the basic cubic form here.
8.6 x 5.6 x 4.3 cm. This is a fine old German galena specimen that came out of the European Wein collection, which was dispersed last year. The crystals have a bluish cast to them, like "blueing" on a gun-barrel. The cluster was removed with a thin rim of accenting matrix around it. The crystals measure to 1.2 cm across.
5.3 x 3.9 x 2.2 cm. A SUPER and UNCOMMON cluster of sharp, lustrous, lead-gray, spinel-twinned galena crystals from the famous Buick Mine of Missouri’s Viburnum Trend. The spinel twins reach 2.0 cm across. Very seldom available and this is a really good one. Ex. George Feist Collection.
7.3 x 4.2 x 4.5 cm. An ELEGANT and SUPERB Sweetwater Mine specimen. A super-sharp, mirror-finish, 3.3 cm galena cube is beautifully set atop a pedestal of tan dolomite rhombs. The large cube is complete all-around, with only a very small contact on the back. Two, smaller galena cubes on the dolomite are a nice accent. A VERY AESTHETIC and EXCEPTIONAL Viburnum Trend specimen. Ex. George Elling Collection.
3.9 x 3.4 x 2.5 cm. Look how unusual this cluster of Oklahoma galena is! Each individual crystal has formed in an uncommon hexagonal form, and they have grown together almost into the form of a soccer ball! You can see a little bit of golden chalcopyrite as well.
16.8 x 13.9 x 6.9 cm. A spectacular, big cabinet specimen of galena crystals sitting on a bed of orangey rhodochrosite - from Peru. The iridescent galenas are as shiny and sharp as machine parts, and their beauty is enhanced by the fact that one, they are isolated, and two, the microcrystalline rhodo is rather dull, which actually enhances the specimen by creating a wonderfully contrasting backdrop for the galenas. This specimen just SPARKLES!
7.1 x 5.4 x 4.1 cm. A gorgeous Eastern European galena specimen, with beautifully articulated modified octahedral crystals that have a wonderful mirror-metallic luster. They sit up beautifully on the matrix, making this a truly aesthetic specimen. The galenas measure to just under 3 cm.
