We made a vulcanised rubber mold of a ring with bead set diamonds
already in place. Does anybody have any suggestions for removing the
left over rubber from the underside of the diamonds? I have tried
soaking in acetone andthen burring underneath as much as possible,
but there is still some residue there. I am concerned about any
future torch work (tipping, sizing, etc) down the line.
