    When I first began years ago, I was very interested in casting. I
    cast everything. I often cast diamonds and sapphires in place. This
    was before the industry wide practice.... There were times that I
    forgot to leave a hole behind the stone in the wax. What this didn't
    allow was the investment to flow behind the stone and support it when
    the wax burned away. Without that little island of investment, the
    stone fell into the mold chamber and then became imbedded in the body
    of the object. I cut apart some of the rings and found the stones
    inside. It would actually be a pretty great project....
