If you want to have something new made out of them, Helzberg Diamonds has a "re-style" event twice a month or so and they will consult with you about what you want done, make a new design and even re-set the stones into new jewelry while you are there. I looked at their website and they have 4 stores in CA so hopefully one is close to you. I would check it out. I know the re-style event and consult is free. They do great work and are super friendly and I think their prices are good too.
