Hi Regina, I have never tried this, but, years ago, I read a
non-glue method for securing pearls. You make the peg by drawing
down a pair of wires together, so they are two half-rounds that fit
together. You then solder them, leaving the top 1/3 or so
unsoldered. Then you make a tiny wedge that fits between them. You
insert into the pearl with the wedge just barely engaged in the peg.
When it hits the end of the hole, it is pushed into the peg,
spreading it and locking the pearl (for all eternity) onto the peg.
That’s the theory. Sounds like a real pain, but I thought I’d pass
it along just the same. It may have said to widen the inner-most
part of the drilled hole with a burr. I dunno, glue sounds pretty
good to me. --Noel
