Using a combination of silver and wood

   ...making decorative pieces of art using a combination of
silver worked in into rocks and or wood 

Information on making jewelry with metal and wood is found in “The Art of Making Fine Wood Jewelry” by Tony Lydgate. I’d try Lark
books or Chester Book Co at http://www.mailordercentral.com/cbc/ or
I notice it is available at about $14 from Amazon.com
