York Stone Quarry, York, York County
5.4 x 4.2 x 2.5 CM (small cabinet/ large miniature)
Transparent Calcite crystals with highly lustrous faces and in choice condition. From the York Quarry which is a famed locality for fine Calcites. This piece has especially good color and the display side is perfect, undamaged, there is a contact and bruise only on the backside not seen in any normal angle. The striations of the faces are very distinct. A very slight melted look is noted on some corners as was common at this locality.
Beryl var. Emerald
6.2 x 4.8 CM (small cabinet/ large miniature)
Classic Colombian Emerald crystal on matrix. Good transparency, the crystal is fairly thick, glassy with basal termination. The color is a very good green but not quite the top superb color which is of course far more expensive. Sits well and stands out in any sort of display. It is very hard to find sizable crystals on matrix that have not been repaired, faked or otherwise unnatural. This crystal is 2.2 x 1.7 CM and is nicely balanced on the matrix. Good condition, there are micro edge chips but no really bad damage, the "bottom end" of the crystal is contacted and does not show a clear termination. This quality is now very hard to get in Colombia, if mined today this would be treated, infused, cut and sold in the gem market. Some good green glass!
Calcite on Galena and Chalcopyrite
Sweetwater Mine, Reynolds County
5.1 x 4.8 x 3.7 CM (small cabinet/ large miniature)
A flawless, gem clear Calcite crystal sits well-exposed on a crystallized Galena and Chalcopyrite matrix. From the Sweetwater Mine (Missouri, USA) Ex. Larry White collection, the Calcite is clear enough that the matrix is seen through the crystal. Sweetwater Mine is famed for its Calcites which often have slightly curved faces. This specimen has some but most faces are perfectly flat and have glassy luster. Best appreciated in person, a fine miniature and great value.
A well-defined, transparent, textbook-form tabular Aquamarine crystal perched on Muscovite. The crystal is in far better than typical condition it has some minor contacts and spots where re-crystallization patterns are seen on the wide faces. Only one chip that is not very noticeable which is remarkable, overall quite fine. This habit of Beryl is rare world wide, it was however strangely more common in 2000-2012 at Xuebaoding. The locality has not been very productive and most of the mining has moved to areas with different mineralogy. These are becoming modern classics but can sometimes still be found at a good price.
Anglesite in Sulphur
Ahumada Mine, Los Lamentos
5.6 x 3.2 x 2.2 CM (small cabinet/ large miniature)
An oddity, from Los Lamentos, the locality world famed for superb Wulfenites, this is a different association. The mine contained a large amount of Sulfate minerals along with the Lead secondary species and some Native Sulphur. This Sulphur mass has both massive and micro crystal areas and is the matrix enclosing several Anglesite crystals about 1 CM in size. Not often seen for sale, this piece dates from the 1970's.
Perfect, gem clear and absolutely colorless, this looks just like ice. A natural sculpture of an etched Beryl crystal, this is also a complete floater, every surface is complexly faceted, etched and undamaged. Not many minerals can exhibit this degree of sculptural etching, however we do see this with Beryl from a few finds and these can be incredible in person. True colorless Beryl (Goshenite) is also quite uncommon, this specimen is displayable from any side or angle, the larger faces are smoothly curved yet striated and it is fully transparent with no inclusions, veils or cracks. Choice.
Datolite (color change) and Heulandite
Prospect Park Quarry, Prospect Park, Passaic County
5.1 x 3.2 x 2.8 CM (small cabinet/ large miniature)
Datolite with a strong color change from artificial to daylight, the color goes from a dark olive-green to a yellow-grey. From a remarkable pocket at the classic Prospect Park Quarry locality in 2008, there were not many pieces found. This has contrasting Huelandites with a warm brown color and shows the uncommon color change phenomenon very well. The Datolite is transparent with many faces being very glassy. There is contacting and bruising that can be hidden fairly well by display angle, so not for perfectionists. Overall the condition is equal to the best I have seen from this find, and a cute Northeastern USA oddity.
Simply extraordinary, a killer Arsenopyrite cluster of sawtooth edged crystals with the very best Iridescence I have ever seen on the specie. From Yaogangxian, this has several small crystals of Fluorite, Quartz Muscovite etc) as is typical at this locality. What is not typical is the brilliant patina on this specimen. A vivid rainbow of colors, this is super in person. I have seen only a few other iridescent Arsenopyrites but never present on more than a few faces and much less brilliant. This specimen is in exceptional condition, undamaged and displayable from any side a rare 360 degree piece. The Arsenopyrite crystals are very sharp and clustered in stacks and epitaxial arrangements. From a small find in late 2018
