Fluorite with Chalcopyrite

Reasonably gemmy to translucent, aquamarine-green tinted cuboctahedral Fluorite crystals form an attractive group with overgrowths of later-stage brassy golden Chalcopyrite crystals.  This large miniature is from the Luise mine at Rottleberode, in Saxony-Anhalt, Germany.  Although all crystals are incomplete (hence the greatly reduced price), it is a good representative specimen from this ancient German Fluorite mine.  Nestling between the Fluorite crystals are clusters of chocolate brown rhombic Siderite, a characteristic species for this locality.  The specimen comes with two older labels.
