Lustrous, tetrahedral sphalerite crystals are richly scattered on limestone matrix covered with glassy, light purple fluorite cubes on this fine old-time combination piece from England. The fluorite cubes resemble the previously described Derbyshire piece and we believe this piece to be from the same area. This old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe. Accompanied by an old German label.
