A beautiful cluster of quartz crystals, overgrown in places by manganocalcite, and associated with sphalerite.  These specimens were quite abundant in the 90's, though when Romania joined the EU many of the once-prolific mines closed.  This piece was brought back by Ross Lillie, though it doesn't have his label-- it does however have that clean, sharpness that the pieces he imported typically do.... there was just *so much* of this material available wholesale (kind of like Bulgarian minerals today) but there are still some specimens that lack the damage and random visual composition that the wholesale stuff always has....his selections always just seemed cleaner.
