Gypsum      Dewitt, Onondaga County, New York.  Ex. John Davis collection.  This is a cool looking bent crystal that measures 8.6 x 3.4 x 2 cm.  It is transparent with some fantastic etching over its surfaces and has excellent luster.  It is doubly-terminated and having fine looks from all directions and both sides.  No damage.  Much better in person.  $90
