An old-time, classic and showy cabinet combination specimen from the Joplin Field of the renowned Tri-State District. Four matte-finished, cubic to modified cubic, galena crystals to 3.3 cm are perched on a 3-dimensional, brecciated, silicified limestone matrix. A lustrous, 3.8 cm, twinned, black sphalerite crystal is protected beneath an overhang. Much of the matrix is coated with a showy combination of iridescent, lustrous, brassy, chalcopyrite pyramids on pastel-pink dolomite rhombs. Ex. Mullane Collection.
