US guides
The inscription is a microscopic number on the girdle, not a logo you can read across a room.
Labs inscribe the report number so a US jeweler can match the stone later with a loupe. Lab-grown inscriptions often include a laboratory-grown mark as well.
Compare the number on the certificate PDF with the number the listing shows. If they differ, stop.
After US delivery, a jeweler can read the girdle again before setting. That is the same check, done in person. 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.
