A bizzare association, well formed slightly translucent Cassiterites sitting on Quartz with a crude 5 CM Stibnite crystal along one edge. The question was recently asked if this is Stibnite or Bismuthinite, and we have not yet made an analysis. The Cassiterites have good luster and form, very three dimensional. Ex Shields Flynn collection, via Bert Ottens, I have never seen another of these. There is a matrix repair that is not visible.
From the now classic finds at Brumado, a very well composed cluster of glassy deep green crystals. In fine condition with a few tiny flecks of adhering quartz otherwise this is all Uvite. Prior to these finds almost all known Uvite was black. There seems to be little to no new production now.
Jeffrey Mine, Asbestos
3.8 x 3.2 x 1.4 cm (miniature)
A bright, two sided plate that hosts several fine gem clear crystals. In excellent condition as seen, all the crystals are well formed and isolated. A small version of the The "front" has the uncommon white matrix of crystallized Prehnite that gives a fine contrast to the Garnets. Choice example that is a small version of the finest cabinet specimens that sell for huge sums.
Ferberite & Dolomite
Yaogangxian Mine, Yizhang County
5.3 x 3.3 x 3.8 cm (cabinet)
Lustrous black Ferberite crystals with sharp terminations contrast with the snow white Dolomite crystals. A nicely composed cluster that looks great from many angles. All the main crystals are in fine condition, there is a contact on one lower side edge that is not seen on display.
Anglesite enclosing Linarite
4.7 x 2.7 x 1.8 CM (miniature)
An great old Tsumeb classic specimen. This is a milky blue single crystal well terminated but cleaved on the base as seen. A tiny bit of Malachite is seen on one edge, otherwise this is all bluish Anglesite. I am told that these were found only in the upper reaches of the first exidized zone (the "green hill"). Not often available with such size and good luster.
Slightly frosted on some faces, sharp, clear and in fine condition, this old specimen is from 1960s vintage finds at Charcas. Selective frosting adds to the visual interest and the form is textbook perfect. The termination shows a nice effect with the selected areas outlining a central hexagon. Nothing quite like these Calcites has since been found.
stock #SOLD 14.1-278
5.8 x 3.8 x 4.6 CM (cabinet)
The deep purple is the most desired (and most expensive) of all the "Cactus" quartz They have not been found in any of the last years of mining. This one is that rich color and has great luster. From the front and sides this is perfectly undamaged. A tiny chip exists on the back of one termination that does not show, yet this keeps the price much lower that would be otherwise.
Carrollite, Chalcopyrite & Calcite
Kamoya, Kambove, Katanga Copper Crescent
Democratic Republic of Congo (Zaire)
3 x 2.6 x 2.2 CM (small miniature/ large thumbnail (toenail))
Fine, sharp silver Carrollite crystals are set on contrasting matrix in an esthetic arrangement. The crystals show complex modifications and growth patterns. Some micro crystals of what looks like Vesigneite are also present. Green copper staining and secondary minerals adds additional contrast. In very good condition which is remarkable for such a delicate mineral. Far better than average.
