OKI-630

OKI-630    Acanthite pseudomorphs after Argentite     Mina del las Rayas, Guanajuato, Mexico.  Ex. Dr. Steve Chamberlain Collection.  This is a special piece for the TN collector who seems to have everything else.  It is the finest of these which I have seen as far as aesthetics go.  Larger crystals can be found and certainly larger prices (mid four figures) but this one has the looks, sharp crystal form and luster which most collectors desire more than crystal size alone.  It measures 2.5 x 1.5 x 1 cm and is somewhat three dimensional.  It branches out in a sweeping display with the larger crystals (to .8 cm each) on its upper sections.  There is no damage to this floater.  There was once contact with what may have been calcite crystals on its backside.  The contact has a thin layer of what appears to be pyrite now forming casts which would have extended over the missing mineral’s crystals.  A truly fine example, and competition grade TN, of material which is usually nearly globular in shape and far lower in luster.   1,500$
