Morocco, Silver, Bouismas Mine, Bouismas, Bou Azer District, Ouarzazate Province

I have listed these specimens under "Silver" as opposed to dyscrasite or allargentum, as other sources have classified them. The silvery, metallic mineral has silver crystal structure/habit in these specimens and I have had them analysed as silver with a couple of percent of mercury. The calcite has been partially etched away to reveal the dendrites. They are GREAT specimens of SILVER!

Item #11391 Silver, Calcite 7.4x4.7x4.4 cm Largest Crystal Size: 5mm $65.00 Bouismas Mine Bou Azer District, Ouarzazate Morocco Silver dendrites are exposed on top and bottom of this white calcite matrix.
Item #11367 Silver, Calcite 3.4x2.1x1.5 cm Largest Crystal Size: 4mm $35.00 Bouismas Mine Bou Azer, Ouarzazate Morocco Lots of bright, platy dendritic silver laced through this calcite matrix.	Item #11385 Silver, Calcite 7.8x4.7x3.6 cm Largest Crystal Size: 20mm $65.00 Bouismas Mine Bou Azer, Ouarzazate Morocco Nice, bright crystals of silver poke out of this white calcite matrix, mostly on the front of this piece but a little on other sides and bottom, as well. Nice example!	Item #19096 Silver 4.0x2.5x2.0 cm Largest Crystal Size: 5mm $45.00 Bouismas Mine Bou Azer Ouarzazate, Morocco Sharp, glistening silver crystals are present on the front of this specimen in three dendritic groups.	Item #19098 Silver 6.8x6.5.6.5 cm Largest Crystal Size: 4mm $240.00 Bouismas Mine Bou Azer, Ouarzazate Morocco There are a LOT of silver crystals on this piece. Calcite has been removed all around to expose many dendritic branches of silver crystals. I expect when shipped, a few crystals may fall off but there are lots! And you can remove a little more of the calcite with vinegar to reveal even MORE crystals of silver. Looks fantastic!
