I have been getting into stone recently, fabulous stuff.  So far I have only worked limestone and yorkstone.  To me the limestone a life to it or a magic I could respond to.  I did not like the yorkstone which is a sand stone and gave up on the carving.  I used the other blocks in the garden.  I would love to have a go at jade or other semi-precious stone.  Clubs can be fondled while watching TV  

  that makes me sound bit of an odd bod.  Stone is nice in the hand.  Anyway I have these very interesting picks of North American jade objects from a small collector series of books called  "collectors blue books, jade, Louis Zara 1969".  Interesting?
