From their website: “What is Solomon Brothers’ return policy?” Solomon Brothers stands behind their merchandise 100%. Although highly unlikely, if you are not happy with your selection, you may return it for a full refund within 25 days. Shipping charges cannot be refunded. All sales are final on any custom made or special order items. No return or exchange can be offered on these type of items. ...I also know that if you want to upgrade a diamond, they will buy back the original diamond at the same price you paid. That's only true for the stone purchased through Solomon, not the band.
I do not believe they do, but you may want to call them directly.
