I have a happy diamond ring and the crystal overlay has turned smoky/black. I knew this would happen eventually, and think it is time to bring it in to the local boutique for them to send out to repair. I might also have to send in the matching necklace as well. Has anyone had to send anything out for the crystal replacement repair and if so, how was your experience? How does the pricing run to replace the crystal? I believe they will probably send it to Miami from the Palm Beach boutique. Thanks!
