The simplest and most effective way would be. don’t scream and run
away. rivet the pearls onto the stud cups.
If you’re making the studs yourself, here’s a basic method, minus
fiddly bits you wouldn’t skip anyway, like pickling, cleaning up any
Cut discs to act as cups for the pearls, dome just enough to cup the
pearl, drill central holes exactly the size of the wire you will use
as posts/pearl pegs. Cut wires long enough to act as the posts, go
through the central hole in the little cups and long enough to go
right through the hole in the pearl with about 1.5mm to spare. Solder
to the cup. Slide the pearl onto the peg, check how much ‘play’ there
is in the original hole. If there is very little, take a bit more off
the peg so you only have say 1mm left.
Polish. Now, hold the earring by the post in a pin vise and secure
that firmly in another vise. Use a riveting hammer and gently tap
down the end of the post to form a neat, rounded rivet.
Even if the hole in the pearl is too small for the thickness of a
normal post (.7 or.8 mm) it is easy to slightly enlarge the hole with
a barrel burr or even a drill bit. Wear a mask, pearl dust is not
good for you!
I almost died of asphyxiation the first time I riveted a 'real’
pearl onto a piece - held my breath too long, terrified of shattering
the pearl. So far, perhaps luckily, I have found that pearls are like
babies - a lot tougher and more resilient than they look.
