US guides
Sentiment does not change the 4Cs.
Some couples replace the center. Some add a pendant or studs. A loose diamond can be any of those if the jeweler can mount it.
Do not assume the original US retailer will credit the first stone. Get the new diamond’s report in hand either way.
Shop the carat and shape you want now, not the story of the first purchase. Carat Mate ships the certified loose diamond and its lab report to United States addresses. Prices on the site are in USD. Wrong-item returns may be considered within 3 days of delivery, subject to review.
