Pyrrhotite, Quartz, Calcite and Sphalerite     2nd Sovietskiy Mine, Dal'negorsk, Russia.   Really attractive display with pyrrhotites to over 2 cm each standing way off the matrix of sphalerite, quartz and calcite crystals.  White quartz form attractive sprays.  Dome shaped piece views well from all sides except back.  Highest luster possible on this first class miniature.  only minor hipping along one edge.  (5 x 4.5 x 4 cm overall size).  This is one I purcasd in the te 1990s when they first came out.  Good examples of this now classic material have become difficult to find, certainly so at this price.   150$
