An exposed geode lined with beige Calcite crystals is host 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 interesting specimen of this classic material from Kentucky. Ex. Richard Kosnar Collection.
