OKP-723     Sphalerite, Pyrite, Quartz, Chalcopyrite, Barite       Yinfengjian Mine, Daigxian County, Fuzhou Prefecture, Jiagxi Province, China.  There is a lot going on here!!  First are quartz followed by large sphalerites, the largest of which is twinned.  On these are chalcopyrites most of which are in epitaxy on the sphalerite (parallel alignment with the sphalerite faces.  Next is a layer of pyrite that almost looks painted on that covers some areas of the sphalerites and most of the chalcopyrites.  Next are very lustrous pyrite crystals that stud most of the specimen.  Finally, plunked in the middle is a small cluster of pink colored barites.  Nothing is damaged and the piece is quite large at 13.5 x 12.5 x 6 cm.  It is even domical in form allowing for excellent views from any side and it sits well on its base which is a contact surface.  Excellent luster and interesting growth features.  Better in person.  $550
