Acanthite and Polybasite on Quartz
San Juan de Rayas Mine, Municipio de Guanajuato
5.7 x 4.4 x 2.3 CM (cabinet)
A melted look sculpture of Acanthite crystals on Quartz also holds a few small Polybasite crystals in sharp hexagons. Choice older piece from the San Juan de Reyas mine in Guanajuato. In excellent condition as seen and with a nice dark metallic patina. Under 20 X magnification I can see glints of blood red color that indicates at least a tiny bit of Ruby Silver (Pyrargryite) is also present but very small.

A well formed thumbnail of complex Acanthite crystals. These show modified cube forms and "melted" look hoppered crystals. A nice dark silver patina and good luster give this a nice presence. A classic Mexican specimen.
This thumbnail Acanthite shows textbook forms and habits in sharp, undamaged crystals that have very good luster. A modern classic locale, the San Juan de Reyes mine has been the source for some outstanding silver minerals, this one is an excellent example.
Some of the weirdest habit Silver minerals and especially Acanthites have come out of Morocco from time to time. This is a very nice example with a sizable chain of oriented stacked octahedrons that displays very well. Somewhat crude as are all of these but undamaged and a complete floater. This came out over a decade ago. The new restrictions have cut off most everything from these great silver mines.

3.2 x 2 CM (small miniature/ large thumbnail (toenail))
An exceptional silver / acanthite from an unusual locality in China better known for Rhodochrosites . This has very well formed acanthites (largest reaches 1 cm) that host a mass of silver wires of several forms. A very nice silver in general and the very best I have seen from this locale. This can be displayed to feature either the silver or the acanthites, both are well presented. 2007 find.
