by pearlsngems » Jul 27, 2019 It's easy to make an extender of any length, not just 2". I've done it. It looks like a very short pearl necklace! As long as the clasp used is the same as the clasp for the necklace, the necklace and extender can be connected end to end. If Cees is going to be stringing the pearls for you, I can't see why he couldn't also make an extender using compatible loose pearls. Ask!
