Hello, I was wondering if someone could speak to the market for a 6-prong tiffany replica setting in platinum. The alloy composition is excellent, being combo of platinum and paladium. The band is not "knife-edge". It has also never been worn and is thus brand new. Size is 6.5. Can anyone speak to what approximate resale value I can receive for it and best place to sell it? Is $1000-1200 too unreasonable? Thanks.
