it seems that you need to restring the whole necklace. is the clasp all right? check it and when it is ok, just seperated all pearls one by one, and have it restrung; but the problem is, the thread for the necklace is hard to find and you need special methods to knotted between each pearls(thanks to the knots between pearls and there's only one pearl falling off), so take pearls to local jewelry store and pay some costs

Yay, so glad you found a bead shop that will fix your necklace. Maybe they can use a different clasp and stronger string since they are rebeading anyway?

Tanya, I'm sure I can fix this for you. Send me a PM and we can arrange a time to get together and I'll bring my tools. If it's a quick fix I'll do it then and there, and if not I will do it at home and get it back to you.

Oh, oops. Just saw that the original post is a year old. I'm guessing you already got this fixed. If not, though, let me know!
