Really different and super attractive. Balls of blue Shattuckite sitting on crystals of bright green Dioptase. The color and contrast are very fine, this is in superb condition. We have handled a few nice Shattuckite balls in the past year but they are always on Malachite, never like this on lustrous Dioptase. This was the only specimen we saw of this quality and condition. It is much more vivid in person too, a very unusual and striking piece that displays well from most any angle. From a recent find at the Onderra Mine (Namibia), we had hoped there would be more but it seems this was a one time find.
An uncommon and attractive Yaogangxian specimen. Lustrous iridescent Chalcopyrite covers most of a stack of flat hexagonal crystals of Pyrrhotite. Only on a few edges are the original golden metallic Pyrrhotite crystals visible. In excellent condition, what may look like bruising on some edges is actually perfect and sharp. The multicolor patina on the Chalcopyrite is bright and sparkling which is both esthetic and very different for this famed locality. Individual Pyrrhotite hexagons are up to 5 CM across yet are unusually thin at just 2-3 mm on average. A choice Chinese Sulfide!
Sulphur - large hoppered crystals
El Desierto Mine, San Pablo de Napa, Daniel Campos Province
6.4 x 3.2 x 2.4 CM (cabinet)
Very pure Sulphur in textbook perfect crystals showing aligned prism forms and hoppered faces. Excellent bright yellow color and in undamaged condition, a modern classic. The El Desierto Mine is a rather small operation located on the flanks of a volcano at very high elevation. It has not been worked for a few years and when we visited the locality some time ago it was really inhospitable to say the least. However the best Sulphur specimens in recent decades have come from here. Better pieces like this have vivid canary yellow color, very bright luster and are rather transparent. The color is much brighter than most specimens of the other classic localities (Sicily and Russia) and there is no hint of Petroleum inclusions that are common elsewhere. These large crystals show very clear epitaxial stacking and exceed 5 CM. Choice for the locale and for the specie. Far better than the usual quality from this unusual place.
