Gypsum var. Selenite, Fluorite with Calcite
Dugupi-Maanshan Sb deposit, Niujie, Weishan County, Dali Prefecture, Yunnan Province, China
Cabinet	12x10x8.5cm	680g
Terminated, transparent selenite x, with soft edges that give it a "molten" appearance, growing on a bed of light purple, fully crystallized fluorite. Further contrast is added by pockets of yellow calcite. Difficult to photograph due to the transparency of the selenite and actually better in person! Found late 2008.

CCN0969	_1850 €
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.
