Pearl Restringing: Most pearl necklaces are strung on silk and individually knotted in between. The silk allows the pearl strands to have flexibility and not hang rigidly, lending to their appeal. Because silk is an organic material, it decomposes over time and breaks. It is recommended to have your pearls restrung every 3-5 years (depending on wear). You can check for "wear" on a strand if the knots are fraying or there is gapping between the pearls and the knots. This indicates that they should be restrung.
