Calcite, Chalcopyrite ps. after Fluorite, Quartz

Focal group of "pagoda"-like stacked crystals of calcite on a matrix consisting of a very interesting - and to my knowledge unique to Dalnegorsk - pseudomorph of chalcopyrite after cubic fluorite. The original cubic shape is still visible because of the quartz overgrowth. I really wanted one of those for a long time and finally found one to add to my collection.
