A classic, old-time and fine cabinet specimen from the Oppu Mine of Japan. Sparkly, iridescent pyritohedrons are richly sprinkled on the starkly contrasting, bubbly, botryoidal, pastel-pink rhodochrosite-coated sculptural, tabular matrix. Rhodochrosite also coats the backside of the crust, but there are very few pyrites there. Excellent, large, combination material from this historic locality.
