|  | BLUE CHALCEDONY DRUSY 
      On closer inspection, you 
      can see that the surface of this material appears much different than 
      drusy agate.  Drusy is commonly used as a catch all for 'field of 
      small somethings', like Uvaravite - small green garnet crystals, 
      Irridescent Pyrite - small multicolored pyrite crystals, etc.  Druse 
      or drusy is a field of small quartz crystals, strictly speaking. |
