Strands restored and reknotted so each pearl has its own knot and the necklace drapes the way it should. This is the pearl-specific half of the hub card that used to share a page with restringing.
Pearl knotting is slow, careful work. We do it at the bench so you can see the strand go back together.
If the strand is beads or a chain rather than pearls, use necklace restringing. If you are not sure, bring it in and we will tell you which service it is.
