Pearls are one of the most elegant and classy pieces of jewelry found in the collection of many women. It is so precious and beautiful that a pearl necklace will inevitably become a priceless family heirloom that will be passed down from generation to generation. Unfortunately, while pearls are very resistant and can weather the elements, the string keeping them together can wear down and break. When this happens, the traditional tendency would be to have it re-stringed or rethreaded by a professional or expert jeweler. However, this repair can cost quite a lot. Fortunately, there is a time consuming way that you can rethread your pearls yourself. The process is complicated and time consuming but with a little practice and patience, you should be able to do it successfully.
Reassemble the design. Once the thread keeping your pearls in place breaks or is removed, the first step in rethreading it would be to place a cloth on a table and recreate the design of the pearls in the necklace. Line it up exactly the same way it was originally lined up on a string. Traditionally, the biggest pearl would always be in the middle however, some designs alternate pearl sizes. Make sure to line it up the way it was before the thread broke or was removed. If your pearls are graduated, then you may need a bead board and lay your pearls on it.
Knot the end of the thread. Get your thread and select the one end and tie it in a knot. This will serve as barrier of the first pearl that you will thread. With this knot, the pearls will not fall off. On the other end of the thread, tie it around the needle. Make sure that the needle and the thread will fit through the hole of the pearls.
Insert a pearl. Once the needle has been affixed and the other end of the thread has been knotted, get the first pearl bead in the design and insert the needle onto its hole. Since this may be your first time, the actual insertion may prove to be difficult especially if you do not have nimble fingers. Nevertheless, with patience and concentration you should be able to do it correctly. As soon as you insert the pearl, pull it down the other end of the thread towards the knot.
Tie a knot after every pearl. As soon as the first pearl slides down, tie an overhand knot after it. Make sure that the knot is close enough to the pearl so that it will not be visible when another pearl enters the fray. After the knot is made after the first pearl bead inserted, place another bead and tie another knot. Continue with the process until you are able to thread all the pearls.
Attach the clasp. Tie the last knot after the last pearl has been inserted to complete the threading. At this point, thread and insert the clamshell clasp and tie another overhand knot after it. Add a minute drop of jewelry glue to secure the thread on the clasp. Do the same for the other end of the necklace. Once the glue dries, connect the clasps of the two ends and the job is done.
Before rethreading the pearls, make sure they are clean and devoid of the variety of skin oils attached to it over the years. Wipe each pearl with a clean cloth. For the thread, use a silk thread, as it is more durable and resistant. Practice often and you should become an expert sooner or later.
