How often do pearls need to be restrung?
It depends on how often they’re worn and what kind of material they are strung on. For June Cleaver types who wear their pearls every day even while vacuuming the house, restringing once a year is probably a good idea. But for the rest of us, every two to three years is adequate. And if your pearl necklace spends the vast majority of its time carefully tucked away in a jewelry box, restringing every four to five years is probably okay. Pearls strung on nylon (e.g. Polyamid) do not have to be restrung as often as those strung on silk. Pearls strung on stranded wire products (e.g. Beadalon) do not need to restrung at all.
