The highlight of this specimen is the unusual, tapering tessin-style, 9.5 cm-tall , lustrous and translucent quartz crystal with chlorite inclusions. The inclusions color it a grayish green . The rest of the specimen is composed of a druse of calcite and several, splendent, brassy yellow crystals of chalcopyrite. An unusual combo for the locality

This solid mass of splendent, brassy yellow chalcopyrite crystals, to 1.5 cm across, is associated with drusy, white calcite. This is a very dramatic and sparkling specimen with incredibly bright luster and incredibly brassy, metallic crystals. It is much better in person, even, and just dazzles in a showcase with light on it.

A gorgeous specimen of unusually large rhombohedral calcite festooned with sparkles! The ivory colored, large rhombohedrons fluoresce a light orange color, and are encrusted with splendent and bright crystals of galena, to 5 mm across. Bright, metallic, brassy yellow chalcopyrite crystals, to 6 mm across, are scattered about on the galena for accent. Overall a very unusual specimen with lots of eye appeal, yet a simple form overall.
I love chalcopyrites, a species that I think many people really just ignore sometimes. But this superb, competition-level miniature, is hard to put out of mind once you see it. It is the most mesmerizing example in its size class I have seen for a chalcopyrite, and just glows with color and brilliant lustre. It is as close to pristine as you can ask, especially in a soft species. Probably from older finds in the 1980s or early 90s, as I have simply not seen anything approaching this quality in recent production here. The piece is complete all around, with the crystals perched on and hanging over a thin shard of glittery matrix, covered with minute sparkling pyrite crystals. This is a competition-level miniature worthy of any major collection, despite its "common species."
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 chalco! Stark contrast of form and color makes this a chice miniature standing out amidst the crowd from these mines.

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

A sharply crystallized example of this classic rare species, in matrix, from THE classic occurrence! The crystal is a rather large 1.5 cm across, quite significant in matrix.
Dreislar is a classic locality for barite, to be sure, but I personally haven't seen STRONTIANITE from here before, and this piece hosts superb crystals of lustrous beige strontianite to 1 cm in size. This barite crystal is not as thinly bladed as normal from here, but rather is a thick, chisel-shaped crystal.
Dreislar is, I think, one of the world's classic localities for barite. It occurs as snowy white, bladed material (as with this piece). However, THIS one is much more 3-dimensional and attractive than most such specimens I have seen, and has rich speckling of chalcopyrite crystals which really offset and highlight the snowy white color of the barite. The piece is almost pristine, with just a few tiny dings to edges of the barite that do not detract and it is in vastly better condition than other large specimens from this locality I have seen, in any case. All is clean and lustrous, the overall effect quite striking! The piece sits on its own without need of a stand.

Top-notch large single Fluorite crystal dusted with tiny Pyrites inside and out. This is absolutely classic for Illinois: superb luster, yellow core and purple to clear edges. Also, it is gemmier than you normally find from Illinois, especially for this size! There is a minor cleave in the rough lower corner, and the tiniest of dings in the upper corner. Neither makes any difference at all to the overall aesthetics, which are terrific.

A truly stereotypical example of the classic "blister ore" that miners loved even more than the finer crysatllized minerals of the day. Why not...its really neat and attractive!? However, because they were not valued so highly at the time by more prominent colelctors, few have been preserved in good shape. this is excellent for the size because of its lustre, color, 3-dimensionality, and aesthetic quality.

Miniature, 3.5 x 3.5 x 2.5 cm Cordierite is one of those species condemned to exist in only ugly specimens of largely crude crystals. Here, however, from a locality I hadn't even heard of before, we have a wild exception to the trend! These robust crystals to 1.2 cm in size have a jet black color, waxy lustre, and excellent crystal form! They are embedded and partially excavated from anhydrite matrix, with golden specks of massive chalcopyrite to set off the crystals even more starkly..
