Acanthite ps Argentite, Silver native with Galena
Hongda Mine, Xiaoqinggou Ag-Mn deposit, Lingqiu Co, Datong Prefecture, Shanxi Province, China
Small Cabinet	5.3x3.3x3.3cm	80g
Enormous acanthite x of 2.5cm (one inch) edge to edge!! This is world-class size for any acanthite x! The acanthite xls on this matrix specimen are exceptionally well developed and show hardly any solution etching. Consequently there is relatively little native silver present, however enough to create a nice contrast to the acanthite. The main x has a small damage on the back side that shows no cleavage planes, clear evidence that this is actually acanthite and not galena, which is also present on this specimen as a minor matrix constituent.
