5.4 x 5.4 x 3.4 cm. A sculptural cluster of large, blocky galena crystals from the Blanchard, ex. Dave Stoudt Coll. Dave Stoudt obtained this specimen at the Socorro Symposium of 2002. Crystals to 3 cm on edge. These are showing altering to Anglesite, although are probably not fully replaced as yet - classic for the locale.
6.2 x 5.1 x 4.4 cm. The pyrrhotite and galena here are intricately intergrown, having formed together, which I have seen before from this locality - though specimens such as this are rare. You can see the characteristic terraced, blocky form of the pyrrhotite compound crystal, with the galenas being small crystals interspersed. There is some sphalerite present as well. This Mexican pyrrhotite has a distinctively different patina from those from elsewhere, such as Dal’negorsk, with a yellow ochre color and shimmering luster.
19.9 x 12.5 x 5.5 cm. Now here is a rich old Colorado classic - a very large plate of sharp galena crystals, from the collection of Dave Stoudt. The display side of this Leadville classic is completely covered with crystals to 1.4 cm on edge, with a "brushed steel" look about them.
9.7 x 5.9 x 5.4 cm. A rich Eastern European galena specimen distinguished by its very ornate, complex crystals. All of them have these wonderful stepped faces. Intergrown with the galenas are some frosty quartz crystals.
5.3 x 4.0 x 3.2 cm. Sharp, intergrown, brown galena cubes to 2.8 cm, nicely accented by sparkly quartz, form a showy and excellent, two-sided specimen from the famous Blanchard Mine of New Mexico. The two, major galena cubes are pristine. Ex. Dave and Emily Stoudt Collection.
5.5 x 4.2 x 2.9 cm. The photo shows very well how dramatic and aesthetic this Eastern European galena specimen is. The crystals have a fine shiny luster, and pretty corner bevels. Minor pyrite and quartz crystals add attractive accents.
3.0 x 2.3 x 1.4 cm. A fine toenail of galena from the Tri-State District, with interesting modifications on the front face and a nice "brushed steel" look.
17.4 x 15.2 x 2.2 cm. During his years living in Poland, collector Dave Stoudt was able to purchase a variety of specimens that have been little seen on the American market and amassed a remarkable collection of Polish specimens here in Texas. This is a galena specimen that simply does not look like one from anywhere else! It is a very large plate of heavy, golden/sparkly marcasite with chalcopyrite, on which have formed maybe 3 dozen galena crystals of around 1.5 cm. Tiny chalcopyrites add a golden sparkle to the galena crystals.
7.3 x 5.4 x 2.9 cm. Check out this remarkable example of skeletal galena - a 1.7-cm crystal whose bizarre form you can see deeply into; on its backside is a gleaming chalcopyrite crystal, and on top of that, a cute little skeletal galena! The galenas and chalcos here are on a bed of milky quartz crystals.
9.5 x 7.1 x 5.4 cm. Large, well-formed, discrete, yet intergrown crystals of galena, to 3.0 cm across, completely cover the matrix and make for a sculptural piece. The crystals have fine luster and a uniform battleship gray color. An outstanding and probably old galena specimen! Ex. Grieger collection.
7.2 x 7.0 x 5.6 cm. Fine galena specimens from the Southern Illinois Fluorite District are not all that common. This large group of stepped galena crystals, to 5.25 cm across, is a floater! It is somewhat elegant with a slightly curved form to it. It has good luster with a battleship-gray color. Sprinkled on the galena are a few subhedral crystals of lavender fluorite. Ex. David Stoudt Collection.
4.3 x 3.2 x 1.8 cm. A beautifully balanced combo specimen from Peru, combining sharp, brassy chalcopyrite with stacked cubes of silvery galena and dark, lustrous sphalerite. You can see a galena cube buried right in the middle of the chalcopyrite! Stark contrast of form and color makes this a choice miniature standing out amidst the crowd from these mines.
12.2 x 7.1 x 1.5 cm. This specimen was very hard to photograph. In person, the dolomite crystals covering the matrix are much lighter in color, providing a striking contrast to the galenas. What makes this specimen so nice is the isolation of these sharp galenas (to 1.5 cm) on the matrix and their pretty balance from one side to the other. Classic for the locality.
5.9 x 5.4 x 5.4 cm. Crowning a cluster of the classic "Blanchard Blue" fluorite crystals (to 1.3 cm) is a perfect cube of galena! (also 1.3 cm). Now, both galena crystals and fluorite are staples from this mine. But, I have simply never seen a galena cube growing right in the middle of, and in fact partly covered by, the fluorites, in isolation! The fluorites here have a touch of purple at the edges, which adds to their own beauty.
7.9 x 5.9 x 4.9 cm. A fascinating and really very aesthetic combo of FOUR Dal’negorsk minerals. On what appears to be a single GIGANTIC compound crystal of sphalerite is a compound crystal of fluorite measuring 3.5 cm across. Beneath this you can see both etched and euhedral faces of galena. And here and there, the gold and purple color is from iridescent chalcopyrite.
