Why Would My Pearls Need to be Restrung?
 
If you wear your pearls quite often, you may want to consider getting your pearls restrung once a year. If you do not wear them that often, then restringing your pearls every 2-3 years is fine.
 
You will know when it is time to restring your pearls when there is space between your knots and your pearls can move around freely. Also, if you find that your knots are looking soiled, it may be time to consider getting your pearl necklace or bracelet restrung.
