Tiffany & Co. silver ring, pendant, and cuff

Everything is brand new and has never been worn; except for the Return to Tiffany small narrow round cuff- which my girlfriend has only worn twice and shows almost no wear. Not able to return or exchange these items in store because I bought them last year and they have a 30 day return/exchange policy. All three items have their original packaging (box, pouch, and bag). The ring is a size 6. The pendant is one size. The cuff is a size small.
