Item Description

Three intergrown, blocky, highly modified calcite rhombs form a showy and excellent specimen from the old lead-zinc mines at Shullsberg. The rhombs are very glassy, transparent to translucent and are a very light tan in color. That's a nicely set ball of sparkly sphalerite microcrystals at the top of the piece. The presentation faces are pristine, with all of the periphery sides being cleaved. This remains a very fine example of the species and well-known locale. Ex Miller Calcite Collection # 870.
