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