Jim & Dawn Minette Collection This specimen started as a very large cabinet specimen, and after several showings I decided it would be more appealing as smaller specimens. The other pieces from this trim will be listed in other updates. The crystals themselves are quite large tennantite after chalcocite pseudomorphs that have often been referred to as “tennantite after azurite”. But this is the only one I have seen that is nearly covered in white smithsonite rhombs.
