          [Pearl  and coral  have  been mentioned  in  these lists  as  "stones"
          because they were anciently thought to be such.  Our knowledge of them
          as products of living creatures leaves us with the ethical question of
          whether or  not  to use  them in  ritual.   This  must be  a  personal
          decision.   Beach gathered coral and  shells (mother of pearl  is from
          shells)  can be  used  without conflicting  with  the above  statement
          because the  creature has already died by the time the item was found.
          If you decide not to use them, just remember leather is also a product
          of a living creature.]
