    You didn't say what size the stone/rock was that you wanted to
    remove or what the dop stick material was. Here's one way that
    I've used successfully in the past with wood dop sticks. When
    using this method with unpolished material you don't have to
    worry about scratching the it. When removing polished material
    more care is required & the procedure is modified slightly. 

    1. Clamp the end of the dop stick in a vise. 

    2. Cut off the dop stick using a saw, as close to the stone as
    possible. 

    3. If the stone was dopped on a polished side that must be
    preserved, cut the dop off just a little short (1/16, .5 mm or
    whatever you feel comfortable with) of the stone. 

    4. Use a knife, sandpaper or grinder to remove the  remainder of
    the dop stick. 

    Many faceters (in the U.S.) use dop wax, epoxy or krazy glue for
    dopping material to metal dops. All of these materials do a
    superb job of hold stones on dops & the stones are easily removed
     at the appropriate time. Clean up is a breeze with any of them. 

    I've never used any of them for dopping rocks for slabbing,
    there's no reason they wouldn't work, but may be a little
    expensive. 100% silicone caulk works well as a cement for dopping
    rocks to wood dop sticks. I've used it for rocks up to around
    50#s. Never had one come off. If the dop stick needs to be
    removed, a hack saw or any carpenters saw can be used.
