For my beaded necklaces, I unhook them and lay them flat on a piece of tissue. Then I roll the necklace in the tissue, kind of like a tissue tube? Then I put it in an organza pouch, looking as nicely as possible ;-) and then in the box, I try to coil it so that it looks nice. But I think customers would be happier that you protected the necklace as your first priority. Imagine scratched pearls, yikes!
