Setting cabs directly into wood

hi i have dug the openings for about ten cabs into wood pendants
that i have made but have now considered filling in the edges of some
of them with some kind of gold leaf or foil, the finish is a 2 part
urethane and is exquisite by itself but as advised by the forum
previously i am wondering about doing the edges, also i went a little
oversize on some of the holes, probably cause i didn’t use an
optivisor, i know this is not similar to kundan very much, but what i
was thinking was to glue the stone and foil counterpart into the
wood, is this ever done, could someone explain the technique,
thankyou, , dave
