An aesthetic example of this classic combo from the famous Linwood Mine in Iowa. Gemmy, modified rhombohedral calcites with inner phantoms of glittering marcasite stacked in a neat cluster. Lustrous and well terminated, I note only a couple miniscule dings that are hardly noticeable. The backside is contacted.
