  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  Crystal 
  (Ezek.  1:22,  with  the  epithet  "terrible,"  as  dazzling  the 
  spectators  with  its  brightness).  The  word  occurs  in  Rev.  4:6; 
  21:11;  22:1.  It  is  a  stone  of  the  flint  order  the  most  refined 
  kind  of  quartz.  The  Greek  word  here  used  means  also  literally 
  "ice."  The  ancients  regarded  the  crystal  as  only  pure  water 
  congealed  into  extreme  hardness  by  great  length  of  time.
