Ferberite    Tae Hwa Mine, Chungiu, South Korea.  Ex. Harold L. Dibble collection.  An outstanding example of this fine material measuring 3.1 x 2.1 x 1 cm.  Great terminations, serrated edges, no damage on front or sides.  Back shows some chipping as seen in backside image.  Inconsequential to say the least.  Sharp form, healed edge contact.  Wonderful specimen!!  $250
