Quartz      Dodge Mine, Edwards, St. Lawrence County, New York.  This large example is a cluster of typically sized crystals and measures 9.2 x 7.5 x 6.6 cm.  Some iridescence.  Good form with some crudely formed (hopper look) spots but most crystals are well formed.  Some incomplete crystals on back but views very nicely from any direction, including back.  Lare groupings like this are very rare for the locality.  $250
