They could be laser attached
Mm how to do it, that is the question.
It's actually quite easy
Yes? Go on then Wendy.
Laser welder works beautifully well for warming the post and not the pearl.
There's other methods too, of course :)
Always assuming the adhesive used is thermoplastic. Who knows what they used though, if they are old?
Here is a discussion on the subject and the answer seems to be using boiling water (or a microwave) , or Attack solvent, or Isopropyl alcohol for plastic glue. But for antique pearls no suggestions.

It'll do shellac, epoxy, superglue - none of them are particularly resistant to heat.
