Sphalerite with Chalcopyrite, Pyrite and Quartz      Yinfengjian Mine, Dongxiang County, Fuzhou Prefecture, Jiagxi Province, China.  This is a twinned sphalerite crystal with lots of accessories.  The crystal has dozens of chalcopyrites in high relief dotting its surfaces.  These chalcos are mostly in epitactic alignment with the sphalerite's crystalography!  Next came the pyrite in a form that looks just like someone painted the material onto the surfaces of the chalcos and the sphalerite.  Next came more pyrite in well formed crystals randomly scattered about on everything!  One tiny cleave to the sphalerite will need to be searched for as it blends in making the piece look to be damage-free.  These are very uncome unlike most mineral discoveries from China.  $375
