An old-time, very rare and superb combination piece from the world famous Langban deposit of Sweden. Sharp, lustrous, gray braunite crystals to 7 mm are richly and aesthetically invested on both sides of the contrasting, very vuggy matrix of solid crystallized richterite. The richterites on this fabulous and classic piece are very highly lustrous and many of the crystals are gemmy. Ex. George English and University of Chicago Collections.
