A small miniature / toenail sized cluster of classic Manganite crystals with no matrix in fine condition. Good Ilfeld Manganites have always been considered the best of the specie and are usually very expensive in larger sizes. This smaller piece is in undamaged condition and shows the crystal form that is so distinctive from this classic old Harz Mountains locality.
SOLD Chalcedony / Amethyst
stock #SOLD 18.1-742
Mamuju area, Sulawesi Barat province
3.9 x 2.4 x 1.6 CM (miniature)
A fine miniature specimen of this now famous material from Indonesia. The best of these new Agates are esthetic, richly colored, have bright luster, no staining, and are very 3 dimensional like this piece. The find has been large enough that the cost of a really good example is now quite affordable. We are told that the area producing the best quality is now more or less exhausted and so these will soon be more scarce. This piece was purchased from a small lot of selected lapidary grade pieces. We are pleased it can now survive in its natural form.
Mahalza, Betafo District, Vakinankaratra
6 x 5.1 x 3 CM (cabinet)
A well-exposed Rhodizite crystal stands on a complex Pegmatitic matrix. The Rhodizite has some gemmy areas and is fairly lustrous, this is a very large sized crystal at 2.8 CM in diameter. Close exam shows a crack and chipping mostly on the backside of the Rhodizite. Still for the size of this crystal it is in quite good condition which is uncommon. Ex. William Hladysz collection and Carter Rich, from the great find over 15 years ago, these were by far the worlds best crystals of this quite rare mineral.
Vauxite on Wavellite
Siglo XX mine, Llallagua
5.7 x 3.7 x 1.8 CM (cabinet)
Excellent, well crystalized Vauxite on a botryoidal crystalline Wavellite matrix. The Vauxite has a fine blue color that is a lot more lustrous and vivid than typical. The surface of the display face is thickly encrusted with fine small Vauxites that are in exceptional condition. A choice example from the famed Siglo Viente (20th century) Mine which is the type locality and the only source of such fine specimens. This plate is a bit larger than typical too and looks even better in person.
Shengus (Shingus) Haramoush Mts. Skardu District
Baltistan, Northern Areas,
3.3 x 2.4 x 1.5 CM (small miniature/ large thumbnail (toenail))
Blocky type crude crystals of Manganotantalite in a cluster that show the red-brown color very well. An older piece from Skardu that has several intergrown crystals these are in quite good condition and most of the faces have very clear striations. Typically this specie has rounded, crude form crystals, often indistinct especially as they get larger. However this is a good deal sharper than most and there is only one spot with a very small contact, otherwise complete on all sides, a floater specimen.
Kelly Mine, Magdalena
5.6 x 5.3 x 3.3 CM (cabinet)
Kelly Mine Smithsonite with the most desirable wet look luster and good blue color. Ex Hitchings collection this is in fine condition a few of the outer edges show where this was removed but all the display surface is perfect clean and undamaged. A few areas of the white mottling are present which adds a nice contrast. This is a pre 1970 specimen. These have become American classics and there is no other Smithsonite worldwide that has just this look, color and luster.
Xiafu, Zhoaping Co. Henzoh Prefecture
Guangxi Autonomous Region,
7.8 x 6.4 x 4.3 CM (cabinet)
A colorful and very well formed knob of botryoidal Smithsonite with good yellow color. Choice and three dimensional, this looks great from most any angle. Except at the base where this was removed, there is no damage or bruises on any surface. The satiny luster is especially rich. These have been marketed as "Cadmium" Smithsonite but there have been some different analysis that conflicts with this and some claim that none of the yellow Smithsonites from any deposit owe their color to Cadmium. I suspect the truth is someplace in the middle. I do not know if Cadmium is involved in this specimen or this find but this is the sought after "Cadmium'" color. Excellent eye appeal and overall esthetics, no matter the color source. An excellent value for one of these complete knobs which are quite uncommon and priced far higher when available.
An exceptional Swiss alpine specimen of perfect curved rhombs in an esthetic stack. From a less well known locality at the Gauli Glacier in the Bernese alps. This zone is not well known for minerals but as the large glacier has been retreating some things have come to light. Recently (August of 2018) a heatwave uncovered a WW2 vintage US aircraft that is the second such wreck uncovered on Gauli. This Siderite is elegantly formed with a few small quartz and Rutile crystals as minor accessories. In exceptional condition and very eyecatching, this is a super Siderite from anyplace but especially choice and rare in such perfection from the Alps.
