Hassle-Free Exchanges

We know that jewelry is one of the most personal gifts you can give; we also know that sometimes your taste doesn’t match that of your partner’s. If for any reason the recipient doesn’t absolutely love the gift you’ve chosen, he or she is able to exchange the item(s) for full credit toward anything else in the store, even if it means having something customized to taste.
