A really very impressive specimen - the sphalerite is huge, it consits of uncountable stepped faces and really all of the show mirror-like luster. The contrast to light tiny dolomite crystals is amazing! The specimen is in perfect condition, the sphalerite is completey exposed - couldn´t be more aesthetic!
