Chalcocite with Calcite    Bristol Copper Mine, Bristol, Connecticut.  Ex. Dr. Steve Chamberlain collection.  Prev. Van King and Neal Yeldin collections.  This example of classic chalcocite measures 3.1 x 2 x 1.6 cm.  There are crystallized area, noncrystallized areas, and areas with breakage, as seen.  The top of the piece is very nicely crystallized and views well from several direction.  I assume someone will trim this up into a very nice TN sized specimen from this historic east coast locality.  $275
