|  | SCHILLER ROUGH 
      The Schiller is mined 
      together with the clear, the red, the green and the bi-color Oregon 
      Sunstone.  Schiller is present in most of the Sunstone.  Mostly 
      it's only desirable if it's in a high enough concentration to shine.  
      Sometimes, it interferes with the red or green and produces a sleepy stone 
      with not an attractive color. |
