A long list of species on this early (2000) Yaogangxian specimen that features a prominent bright purple Fluorite. The Fluorite is a stepped cube that shows perfectly the stairlike form of this habit. In excellent condition, this has an intense deep color and contrasts with the other species on the specimen. Esthetic and an unusual habit for this famed locality, the stepped form is better known in Green crystals from Shangbao (Hunan Province) but very rare at Yaoganxian.
Barite with Stibnite
Xikuangshan, Lengshijiang, Loudi Prefecture
10.1 x 6.8 x 4.2 CM (cabinet)
A series of lustrous crystals in alignment that forms a cluster much like a winged figure. A few Stibnite crystals are on and in the Barite, but the main attraction is the Barite itself. The crystals show epitaxial arrangement and have stepped modifications on terminal faces. In good condition overall, there are very minor edge rubs found on a few edges but not evident without magnification. A very nice example of this important find and an esthetic arrangement of good transparent Barites.
A classic, well formed English Fluorite that has a prominent, isolated main crystal that is dominant on this specimen. Chalcopyrite and small Quartz crystals are scattered on the display surface. Strong deep color, in fine condition and vividly fluorescent, ex Hitchings collection. This is a pre 1970 specimen and possibly much older, a classic Weardale piece that displays well.
Large, perfect gem clear crystals of Albite with fine textbook form. Ex Rock Currier collection (label # 3856) this shows well the quality of esthetics that Rock was well known for. It is surprising how few collections or even Pegmatite suites we see have a good example of this common Feldspar. These are almost never so esthetic as seen here, this is a striking piece. Albite/ Cleavlandite is a common mineral, but crystals of this size and perfection are just very rare. These crystals are formed as thin hexagonal plates with beveled edges and transverse striations. The whole group is stacked as an epitaxial cluster and shows brilliant glasslike luster. A killer Feldspar, some edges have a dusting of small rosettes of Muscovite that add a nice contrast. Better in person, the individual crystals exceed 5 CM diameter.
Fluorite with Quartz
Cantera Llamas, Duyos, Caravia
2.5 x 2.1 x 2.1 CM (thumbnail)
Pristine thumbnail of Fluorite cubes having clean beveled edges and a delicate purple hue. The cubes are fully transparent with a slight frosting on some faces which under strong magnification seems to be a complex recrystallization. In perfect condition damage wise, this is a nice example from this small but important locality that has been sporadically producing small numbers of specimens but sometimes of very fine quality. The matrix is perfectly visible through the crystals and the Fluorite is nicely perched at a nice display angle.
A fan of terminated crystals of dark colored Samarskite nicely perched on a typical Pegmatite matrix. The crystals reach 3.5 CM and seem to be doubly terminated (lower termination is partly hidden by matrix). A nice example of this rare earth mineral from North Carolina, these are not often seen on the market from anyplace. Some adhering Mica is seen on a few faces which could be removed but it seems to add a very nice contrast to the dark Samarskite. In fine condition, usually these are rather crude crystals but this specimen is quite well defined.
Elegant form of flower-like Amethyst from the amazing collection of Rock Currier (his label number 4990) . Perfect, 360 degree specimen with the fine esthetics that Rock was well-known for. He imported large quantities of Amethyst from this area and kept just a small but choice selection, of which this is one. The Quartz casts have the square cross section and are hollow as is typical of Anhydrite replacements. This is not exactly the typical form from here and that certainly helped make this a desirable piece for Rock.
N'Chwanning II Mine, Kalahari Manganese Filed
Northern Cape Province,
3.1 x 2.6 x 2.1 CM (thumbnail)
A sharp and very choice thumbnail of Thaumasite crystals on matrix in excellent condition. The crystals all have a pale color and are transparent with a slightly milky look at some angles. The largest prism is just under 2 CM long. No damage. The best of this uncommon specie was found a few years ago at NChwanning, and those are now quite scarce. This piece is from that find.
