13btrmar ((SPHALERITE)), $10 MINIMUM BID, Racracancha Mine, Pasco Department, Peru, 4.5 x 4 x 3 cm, Miniature | |
Here is a neat Sphalerite with tetragonal crystals of Sphalerite. The faces look velvety but is not soft. I only saw three of these at Tucson in 2013 from a Peruvian dealer and probably limited and in with other minerals from this mine which produced Pyrites in 2013 that seen to be first available at Tucson in 2014. |
