Flower-like cluster of well crystalized Silver minerals perched on a sparkling white plate of Calcite. Esthetic composition with nice contrast as well. The largest crystals in the cluster are the Pyrargyrites which reach over 8MM and are the flat terminated habit. These are quite dark as almost all red color is gone, but with nice distinct form. The Polybasite crystals are more numerous but smaller, most showing the classic flat hexagonal habit. With a loupe there is some damage seen on the delicate thin edges of some Polybasites, Overall the main Silver specie cluster is excellent by naked eye and a few small balls of Calcite decorate the darker minerals nicely. Ex Charles M. Noll collection his label is included.
Tantara Mine, Shinkolobwe, Kambove District
Democratic Republic of Congo (Zaire)
3.3 x 2.8 x 1.8 CM (small miniature/ large thumbnail (toenail))
Emerald green and glassy Dioptase crystals in a very nice cluster from the Tantara Mine (Katanga). The largest crystal is just under 2 CM, there is no matrix just pure Dioptase in very good condition as seen. The Dioptase from Congo does not have the ultra bright luster of a fine Tsumeb specimen but can be a bit brighter than many from Kaokoveldt. This piece is of that sort, better in person and quite esthetic. Congo Dioptase is not often available, it seems to be found every decade or so in small batches and then there are none for years. This was mined in 2012.
A fine, well crystalized old Danburite from Russell, New York. A classic of the Historic St. Lawrence County region, this specimen is from the late Ingeborg Burggraf collection. Several zones on the matrix host dense clusters of Danburite crystals with several habits, most being transparent to translucent and fairly glassy. The crystals reach over 1.3 CM though the majority are smaller. Uncommon on the market, the clear type like this are usually somewhat smaller in size this is well above average for quality.
Cobaltoan Calcite with Malachite
Kolwezi, Katanga Copper Crescent
Democratic Republic of Congo (Zaire)
4 x 3.7 x 3.5 CM (small miniature)
A small, colorful and cute specimen from the Katanga Crescent (not the more common Moroccan type). There are two separate vugs on this piece with brightly sparkling purple-pink crystals and a few sprays of green Malachite adding contrast. Some bruising on edges is noted but still a pretty and affordable small piece.
stock #20 AE-7-082 B
Parun Pegmatite Field, Wama District
5.4 x 3.2 x 3.1 (cabinet)
A big, glassy crystal with a very dark blue-green shaft becomes a lighter blue near the top, then grades to a water clear zone and ends with a thin reddish purple cap. Well terminated with a transparent flat top and with great luster. In very good condition, with only very tiny bits of edge wear that is not easy to spot and a small unobtrusive chip on the back. An older piece this color combination is not very common. The top portion is all gem clear but the majority of the crystal is rather dark and only a little light passes through. Displays well and a good value for a stout single crystal. A hefty 106 grams.
From the Idar Oberstien area that is famed for its Basalt flow minerals most notably fine Agates. This is a delicate and sharply formed replacment of a flowerlike spray of Glauberite bladed crystals enclosing a vug. All the Glauberite are now replaced by Quartz with the inner part showing a zone of Amethyst fingers. Some fingers show the hollow void where the Glauberite crystals had been. An older specimen ex Ruth Palmer and William Hladysz collections. This is a bit similar to some New Jersey (USA) casts often seen with Prehnite replacing Anhydrite.
Cerro de Concordia, Piedra Parada
9.4 x 7 x 4.1 CM (cabinet)
A flowerlike arrangement of large, gem clear and perfectly undamaged crystals perched on matrix. The two largest crystals are sceptered, though that is best seen on the backside of this piece. The best specimens in this more recent find (2017) were sculptural and had great color, luster and form, somewhat differnt from previous discoveries in this zone yet still recognizable as clearly from Veracruz. This is such a recent piece, flawless and the overall esthetics are top percentile. The matrix has a nice dusting of drusy colorless Quartz on the front side which makes a nice contrast with the Amethyst.
An important and choice Almandine on pegmatite matrix from the 1974 Dagenais Pocket (named for Rene Dagenais). This specimen was in the collection of John Marshall who was at that time one of the owners of the locality. According to John it was the best Garnet he had seen from Mt Mica. The specimen retains his painted on label and collection number M-19. The Almandine is mostly complete with dark red higlights. There is an area of damage on the backside but the front is clean and presents well. Garnet is rather common at the famed Mt Mica, but any well formed crystals are especially rare. A significant specimen from a famed pocket and important for the locality.
