Restringing is fundamental to the preservation of pearls and gemstone beads. The standard wisdom is to restring every year or two, depending on the frequency of wear. At Tena's Jewelry, we use luxurious silk thread and nylon thread for knotting and stringing of pearls and a heavier thread for bead restringing. We seperate each pearl or bead with care and individually knot for safety. However, some gemstone beads are not desired to be knotted and these too can be restrung in the same manner without the knotting technique.
