Calcite with Chalcopyrite Calcite with Chalcopyrite Calcite with Chalcopyrite

Superb quality Calcite crystals on matrix with Chalcopyrite. We have all seen hundreds of these, but this one is exceptional, one of the best I can recall seeing in terms of glassy, gemmy crystals and freedom of damage. It's also a floater crystallized all around. I found one small crystal on the top rear (not part of the main group) that was incomplete, otherwise it is perfect. Just released from an old collection.
