6.1 x 5.5 x 2.3 cm. This fine Kansas galena specimen looks like a piece of modern art, does it not? There is no matrix here, just these gorgeous sharp crystals stacked together and in some cases barely touching one another. Very elegant for this style, I think! From the old Tri-State District, 1930s-1960s.
5.4 x 3.6 x 3.2 cm. Dramatic upon a quartz matrix, these hollowed cubes of lustrous galena crystals, to 1.6 cm across, exhibit incredible etched, skeletal growth, where only the crystal edges remain. There is one crystal on the lower left edge that had its etching interrupted, because most of the crystal is still intact. Although etching can and does appear in many mineral species, this occurrence in a primary lead mineral is just flat-out amazing.
4.4 x 3.9 x 2.2 cm. One superb crystal of skeletal, battleship gray, galena, measuring 1.3 cm in length, is aesthetically perched on other galena crystals exhibiting various stages of etching. For added effect, scattered on the galena are several crystals of resinous, translucent yellow crystals of sphalerite to .6 cm across. The etching, and color contrast is super!
5.5 x 3.0 x 2.8 cm. A massive chalcopyrite matrix sporting brassy yellow crystals to 1.5 cm in length is the host for a small cluster of etched, skeletal, battleship-gray, crystals of galena. The rear-right side of the matrix was sawed to remove it from the pocket, though this faces the back. These crystals, which reach 1.5 cm in length, are so eaten away, that only the crystal edges remain and are slightly twisted as if caught in a storm. Superb example of this rare habit!
5.3 x 4.4 x 2.4 cm. This well-balanced matrix galena specimen is covered by a bed of green, chloritic to colorless, gemmy, lustrous quartz crystals, to .75 cm across. Perched aesthetically on the quartz are three lustrous, skeletal, battleship-gray galena crystals, to 2.5 cm across. They are more elegant than boxy, if that makes sense to say, though they are technically box-work in form. It appears that the largest crystal was octahedral in form rather than the more ubiquitous cubes. Truly dramatic and unusual! More 3-dimensional in person, too!
4.1 x 3.2 x 2.8 cm. Almost a complete floater, this crazy-looking, surreal cluster of lustrous, skeletal, battleship-gray galena has crystals to 2.75 cm in length exhibiting several stages of etching. Perched aesthetically at the top is a superb and elongated hollow crystal, where only the crystal edges remain. It looks more like sculpture than crystal!
4.8 x 3.8 x 3.8 cm. Massive galena with some associated quartz forms the matrix for skeletal, lustrous, battleship-gray, galena crystals to a whopping 2.5 cm in length. You can imagine how few of this size might survive?! This is more lustrous than others here, for some reason, and is MUCH ORE 3-dimensional in person. The crystals exhibit various stages of etching with the largest crystal displaying only crystal edges. Dramatic!
7.4 x 5.0 x 3.7 cm. Gemmy quartz crystals, some doubly terminated and chloritic, are the matrix for skeletal, lustrous, battleship-gray galena crystals to 1.6 cm in length. A few, small brassy yellow, chalcopyrite crystals abut the galena crystals, on the back side of the specimen. I particularly like the way the galena crystals are perched high on the matrix, very dramatically.
8.4 x 6.0 x 4.3 cm. Note this is one of the largest specimens recovered in good condition, with any aesthetics to it; and is also particularly balanced and well-trimmed. The etched, skeletal, battleship-gray galena crystals are beautifully perched on a matrix of colorless quartz, with nearly all of them exhibiting amazing etching to their hollow cores, where only the crystal edges remain. Magnificent and aesthetic for the rich contrast to quartz!
7.6 x 5.8 x 5.5 cm. A classic cubic Galena crystal with sharp, splendent faces and great form. Not nearly as common on the market as they once were, and are easily some of the most well known American Galena specimens extant. Ex. Brian Kosnar Collection.
5.3 x 5.2 x 3.4 cm. A unique Eastern European galena specimen! If features a single large, floater crystal of galena that has grown around a number of gemmy quartz crystals, arranged perfectly around the periphery of the galena. The large termination face of the galena cants towards you, and you see the tips of the quartzes sticking up around it like a decoration. The orange color you see is micro-calcites on the back sides of the quartzes - you are seeing through the clear crystals. A really aesthetic specimen!
7.4 x 5.4 x 4.2 cm. Wonderfully sharp crystals of galena to 3 cm on edge, with a fine mirror shine that does not come out in the pic; associate here with brassy chalcopyrite. The smaller galena stands out really 3-dimensionally, as it has only a very small matrix attachment. Fine old Tri-State piece.
8.4 x 6.4 x 5.9 cm. A beautiful combo of a golden calcite crystal rising right beside a razor-sharp galena crystal positioned just right on the matrix. The smaller "sidecar" crystal is cleaved, but it is really not important in the context of the specimen as a whole.
6.2 x 5.2 x 3.8 cm. The pic gives you a pretty good look at the flashiness and architectural beauty of these flattened, spinel-twinned galena crystals - ranked attractively in tiers, with quartz crystals intermixed. A fine Eastern European example of spinel twinning in galena, in a nice small cab size.
12.2 x 6.4 x 5.2 cm. A classic old Tri-State combo piece that has it all: a large, waxy, complete and doubly-terminated calcite crystal associated with brassy chalcopyrites and little galena cubes, on a matrix of dolomite.
