We offer our customers a lifetime upgrade on their original engagement diamond, solitaire diamond pendant or diamond studs purchased from Christopher William Jewelers, for a different size, quality, or shape. Upgrade policy applies to Natural Diamonds only. Manmade and synthetic diamonds are excluded. If you are looking for something different or larger, we are happy to make that a reality. You will receive your full original purchase amount towards your new purchase. The new item must be at least the original price plus 50% and a single item at retail price.
