    Apparently you have yet to grasp the concept of gold annealing and
    how to treat different Karats. you must heat to dull cherry for 14 k
    and then quench in alcohol after the red dissapears. if you allow it
    to air cool it aligns the molecules as before, quenching after the
    red dissapears mean you will have maximun space between atoms at
    that point! 10kt is more redness when you quench as the atoms are
    more mixed in lower alloys and the critical stop will cause cracking
    if you quench to fast or soon. alcohol being the prefered quench as
    it dissapates heat faster with less shock. the higher the karat the
    longer you wait till quench as the atoms are more consistant and
    hold the red inside longer. when you are heating the metal coat with
    boric acid and alcohol to reduce firescale. Then heat till you see
    the metal relax holding the bezel shape is not important at this
    point. the other way to get this accomplished is to make sure your
    bezel is exact and then solder. quench in alcohol immediately after
    hard solder flow. then strech over stone and solder to silver. use
    silver solder as gold will create utetic and that will interfere
    with solder flow! 

Hope it helps ya
