This substantial 12.7mm White South Sea Pearl is set with Emeralds and Blue Sapphires to become one of my patent pending Pearl Gemstone Clasps.You would send me your classic pearl necklace and I would finish the clasp and restring your necklace to it. Very simple and then you have a modern and unique piece of jewelry that you will wear often.

The second photo is of some 8.5mm Akoya pearls next to the clasp to give you an idea of how this might look in your necklace. Sorry the Akoya pearls are not included.
