Not sure if this is the right category for this, but we'll go with it

Wondering if anyone has successfully sold or redesigned their engagement ring. I am trying to decide what to do with mine and am stuck on ideas. I have an antique setting that I've basically just outgrown, and because it's not a set with my wedding ring, I haven't worn it in years, so it's just sitting collecting dust (and I'm paying insurance on it). I looked into a redesign, but most jewelers are talking upwards of $1K and basically a new setting. I'm not a big jewelry person anymore, and since the stone itself is decent quality, I was thinking about selling it and just adding the money to savings/house projects (realizing that I won't get the same $$ we paid for it). Wondering if anyone's done anything with theirs and has vendors/sites/ideas to share. I'm not even sure where to start. Thanks!
