Millerite (ex Rich Kosnar Collection)

Item Description

An exposed geode lined with beige Calcite crystals is hosts to some small, bright metallic needles of the well known Nickel Suflide, Millerite. There is a group of almost reticulated Millerite crystals that have a geometric (preferential) pattern which have overgrown a single Chalcopyrite crystal in the vug. There is also another Chalcopyrite which has no Millerite coating it whatsoever. A very cool specimen of this classic material from Kentucky.
