The Certificates for Your Diamonds


A detailed certificate from an independent diamond institute, such as GIA or HRD, is issued for your piece of diamond jewelry of 0.50 carats or more. In addition, you will receive our Wempe certificate of authenticity with a four-digit, unique serial number, which is also engraved on the piece of jewelry.
