JC10555.  Ferberite.  Cerro Tazna, Nor Chichas province, Potosi, Bolivia.   5 x 5.5 x 5 cm  351 g.  $95.00    Nice group from this location which hasn't produced more of these for several years.    Black, bladed crystals.   Broken crystal on the lower front.  
JC10555.   Closer view.   The greenish tint on the crystal face on the left is a reflection, as it is dead black in color.  
JC9785.  Ferberite.  Tazna mine, Cerro Tazna, Atocha-Quechisla mining district,Nor Chichas province, Potosi, Bolivia.   5.5 x 8.5 cm   597g.  $250.00.   Nice group of black, sharp crystals with good, bright luster.   The top crystal (edge on in this view) is 3 cm across, and is shown in better view on the bottom photo.   There is a broken crystal on the extreme right side of the piece, visible in the photo.  The main crystals are fairly clean, although there is a tiny ding on the right edge of the main 3 cm crystal, visible on close examination.  Considering how brittle these specimens are this one is in good shape and displays well. 
JC9785.  I rotated the specimen a bit for this photo.  
JC9785.  View of the 3 cm crystal.   The specimen has to be rotated a bit to show the face of this crystal, which I did for this photo.   The broken crystal I mentioned on the main description is visible on the lower right.   When displayed as shown in the topmost (first) photo, it is not obvious.
