    For carnelian- just make sure the patina doesn't seep in under the
    stone...(then you would have a darkening of the bezel floor, thus
    changing the color of your stone) . With other stones, my advice 
would
    be to consult a book or chart that tells you the porosity and/or
    hardness of a stone. and then make an educated decision (or just
    experiment with cheap stones) 

    I think the BIG answer is in the APPLICATION of the patina ( and
    what patina you use- some are more caustic than others) I would
    choose to PAINT on the liver o' sulfur instead of dipping- just to
    have more control over where I have a patina. 

    I hope this makes sense and helps- Happy smithing!- Maureen BZ 

Don't worry, B. Zappy
