Art Clay w/ created sapphire

Art Clay (refer to section discussing art clay) formed into a tube set with created sapphire.  Tube is .999 pure silver.  Piece is on sterling chain.  Chain very dainty.  When working with Art Clay, it is very difficult to create tubes.  Usually I wrap it around a straw, but the trick is to remove it when it is not too soft or it will deform.  If too dry, you risk breaking the piece as it is very brittle in the dry state.
