Proustite - Ruby Silver crystals
Imiter Mine, Imiter Mining Dist., Tinghir Province
5.7 x 3.8 x 2.8 CM (cabinet)
A fine and esthetic specimen of nearly pure dark red Proustite in distinct crystals. Proustite is a true mineral lover's specie, the most desirable and rare of the "Ruby Silvers". Good specimens are prized and great ones are very highly valued. This is an excellent piece very fine for the locality which is one of the small number of sources for great specimens worldwide. This displays well in several orientations, it is crystallized on nearly every surface. Incredible under magnification too, with good lighting the Proustite is a brilliant ruby red and translucent. In excellent condition damage-wise, which is also rare for this delicate mineral. Several different habits are present, some seem to be twinned and the smallest crystals are clustered in rosettes and balls, the larger crystals are more distinct and somewhat separated. Super choice.
An exceptionally rich, very pure mass of crystalline Proustite that has well preserved color and is fully translucent. With strong backlighting this glows like a chunk of dark red glass (we have not backlit the photos here so it gives a realistic view of the mineral in a normal display). There are numerous complex crystal faces, etched surfaces and edges on this piece but also to note some chipping too. Overall in fine condition for such a very old, vintage specimen. It was suggested that this could be considered facet rough gem stock though that is not what we do. The total weight is over 68 Grams which is certainly a lot of red Silver. With magnification some sharp complete terminated Stephanite crystals are seen. These are small but very fine with an elongated habit that make a nice association. This is from the type locale and especially choice for the large size, condition and quality overall.
Deep red small crystals of Proustite scattered on a complex mix of tiny yellowish Quartz crystals. A nice thumbnail of a "noble" Silver mineral that has several different habits showing. With magnification some broken areas are noted which is typical for most Proustites but all in all this is a cute and fairly rich specimen from a classic locale. Ex. Wm. Hladysz collection, he acquired this in 2003.
A large and nicely textured chunk of Native Arsenic is loaded with vugs and zones of sparkling small crystals of brilliant red Proustite. From the famous old location of Schlema, this would be a very good specimen of Arsenic all on its own. The addition of bright Proustite makes it quite special. Many of the Proustites have damage as seen on magnification but some of the crystals are pristine and complete. They have not lost the Ruby Silver color so this makes a nice contrast
Bou Azzer District, Tazenakht, Ouarzazate Province
Souss- Massa- Draa Region,
6.5 x 5.8 CM (small cabinet/ large miniature)
A very rich, estheticly presented and fine specimen of the rarest of the Ruby Silver minerals, Proustite. A large 4.6 CM crystalized mass of nearly pure proustite in association with minor acanthite crystals rises from the matrix. There is no visible damage even under 10x magnification. The individual proustites are brilliant ruby color, lustrous and well formed up to 3 mm in size and arranged on clusters. A great piece that shows the specie well from a great Silver locality, While this is not going to compete with the best old German and Chilean examples, it is affordable and pretty. This is one of the best I have seen from Morocco, likely from the Imiter Mine but I can not confirm the locality beyond the Bou Azzer region.
