Dawn,

    There are several abrasive wheels that can be mounted in your 
    Foredom which can be used to cut and shape stones with the hardness
    of  turquoise. 

    There are aluminum oxide cut-off discs that range in size from  7/8"
    to 1 1/2" in diameter. They can be mounted on a mandrel in your
    foredom handpiece. 

    There are silicone cut-off discs that range in size from 7/8"  to 1" 

    There are diamond sanding discs that mount on the end of a  mandrel.
     These have the advantage in that the mandrel screw does not 
    interfere with sanding.  

    Check out the catalog of jewelry tool suppliers 

    The size of stone you can cut and shape into a cab is limited  in
    the size of disc you use.  You can easily cut and shape stones up to
    an  inch in diameter with the larger cut-off discs.  

    The process is time consuming and creates a lot of dust unless  you
    cut under a water drip system. I made a lot of inlay jewelry using
    cut-off discs and my Foredom until I bought a rock polisher. 

    Contact me off line if I can be of specific help in describing  the
    process.  I could send photos of the process.
