Silver var. Kongsbergite on Calcite

Item Description

A rich, sculptural and aesthetic leaf silver plate of kongsbergite : Kongsbergite is the so-called mercurian variety (about 5%) of silver and is quite rare, worldwide. This piece has been analysed (I am told) but in any case is reported from this mine on MINDAT (https://www.mindat.org/min-2250.html) and is from a well known pocket found a few years ago. This two-sided piece has variable luster from side to side, silver-metallic to matte gray. It is aesthetic, perched up like a sail upon nice white calcite matrix with minor quartz in association. A fine example, aesthetic, and display quality. Valued $1200-1500.
