I am almost afraid to start this; but there are optional mechanical
methods for securing pearls. The first and easiest to explain:
Take a 4/0 or smaller saw blade and split the end of the mounting
peg for half of it’s length.
Now file a wedge onto the end of a wire, gauged to fit the pearl
Carefully measure the depth of the drill hole in the pearly with
the wire and mark it.
Subtract the length of the uncut depth of post and cut your wedge
to that length.
Place the wedge into the end of your saw cut in the peg and place
your pearl onto it.
Push the pearl home, seating the wedge.
It takes some practice to do this regularly but it can be done
adhesive free if desired.
And my 2 cents, ( less depreciation ) on the super glue is that it
becomes too brittle to secure any pearls exposed to even moderate
wear. Use epoxy.
