Take a warm ball of Jett Sett and squeeze the lower third in a ring
clamp. Then, allow to cool. To use re-heat the top of the ball to
secure the item of jewelry and re-clamp the ball in your ring clamp.

Brad - this sounds good, but how do you propose heating the top of
the ball? I have used Jet Sett and it takes quite a soak in fairly
warm water for a good size ball to get soft and pliable.
