My moms high end costume jewelry.

I know this may sound crazy, but here goes. First my mom is not tech savvy and I've offered to find a great home for these remarkable pieces. Full disclosure I'm not aware name of designer. Prior to my dad's health issues my parents cruised at least 3 to 4 times a year. The magnificent pieces were only worn once and kept in family safe. These bangles can be worn in array of combinations. They are gold and/or Pearl like designs, will not tarnish, no scratches and I'm willing to sell all 4 together or mix in match...so ignore price and make me offer..bit confused how to price fairly. Let me know if you questions.
