Diamonds are forever, but the rings they’re set in don’t have to be. It’s never a bad thing to take another look at the pieces that are part of your collection and judge that they need an update. Whether that’s a years-old engagement ring or an inherited diamond jewel that only sits in your jewelry box because it isn’t your style, remounting stones has always been a savvy practice, even at the most rarefied heights. (Royal families are masters of recirculating theirs in new designs.) And making use of stones you already own is a common sense, sustainable move, so get inspired and remount yours in pieces that suit your current circumstances and preferences.
