Cultured pearls are strung with silk thread or nylon bead cord with a knot between each pearl.  This keeps the pearls from rubbing together and prevents all of the pearls from cascading to the floor if the necklace was to break.

Both Silk and nylon  is susceptible to wear and tear, especially if you wear the necklaces all the time. The fine silk or nylon  can stretch and weaken, so if you see extra space between the knots that separate the pearls from each other, that could be a sign that the necklace needs to be restrung.
