Gersdorffite with Annabergite
Alt Ahmane, Bou Azer, Tazenakht, Ouarzazate Province
4.2 x 3.5 x 2.7 CM (miniature)
Gersdorffite in good or sizable crystals has been super rare until this one small discovery. This is a very fine piece and is the best example we have had from the world class 2014 Bou Azzer find. Sharp lustrous octahedra in a cluster with contrasting green Annabergite shows this Nickel specie well. A brittle mineral, this has some cracks and chipping on some crystals but overall is in exceptional condition. Sharp crystals to 2.3 CM is quite impressive for this specie.
A group of three Diamond crystals, each with a slightly different color hue and very different crystal habits. From an old collection, these total 1.55 Carats. The largest crystal is a penetration twin cube the middle size is a cube with half of its faces having hopped indents and half with growth hillocks and the thirst seems like a cyclic discoidal twin. Under magnification many small modifications and extra faces are seen. Sharp and a nice suite of Carbon!
An oddity from the great Yaogangxian Mine, sharp rosettes of Pyrrhotite (rare at this locale) that are coated by secondary Sulphides and associated with Chalcopyrite and Pyrite. The Pyrrhotite has been partly or entirely replaced by what is likely pyrite but could also be Chalcopyrite. Both species are on the specimen's matrix. Delicate and well-formed this was part of a small find we obtained at the mine in 2003. I have not seen these since then. Uncommon and a nice example for any good Yaogangxian suite.
Wulfenite with Mimetite
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
4.6 x 3.4 x 2.4 CM (miniature)
An excellent, fine, delicate and colorful specimen of windowpane Wulfenite on matrix. A few tiny bits of Mimetite are found on close inspection. In incredible condition for such a delicate mineral, with good magnification I can find only one tiny chipped crystal that is out of sight anyway, essentially perfect. This was found in the last mining attempts at Rowley, that project is now finished and there may never be any more of these. A clean, classic and very esthetic specimen.
A sizable pure mass of Cuprite, nearly all crystallized with individual crystals reaching 1.5 CM. A few small vugs have some hairy Cuprite var. Chalcotrichite, in excellent condition overall, this is a rich specimen from a classic locality. Better in person.
Ilfeld, Nordhausen, Harz Mts
5.7 x 4.1 x 2 CM (cabinet)
A fine, old German Manganite with very lustrous metallic crystals. Looks good on all sides but the "front" is a bit better. Typical crystal habits reaching to 3.3 CM. Some contacts and breakage keeps the price very low for one of these classics yet this still displays quite well.
Fluorite - new find
Hameda, Jorf, Er Rachidia Province
7.9 x 5.8 x 3.9 CM (cabinet)
Glassy bright yellow Fluorite with sharp transparent cubes in an esthetic cluster. From a new find in the Hameda area that has produced much better than previous specimens. Choice display specimen with distinctive habit and color. All of the main crystals are perfect, undamaged which is rare in a Moroccan Fluorite.
A choice single scalenohedral Rhodo crystal with a small bit of matrix adhering to the back and bottom. Super bright color and sharp, glassy prism faces. The lower termination has some contacts on the back side but otherwise this is in super fine condition and the front side displays very clean as seen. An excellent Peruvian thumbnail that looks a bit like a South African. Choice.
