Late stage vein assemblage of pink rhombohedral rhodochrosite crystals; pale green, translucent, long-prismatic willemite crystals; and a patchy, silvery coating of (probably) a chlorite-group mineral. The chlorite detracts from the aesthetics but makes the specimen more interesting scientifically.
