Mervis Diamond Importers subscribes to the highest ethical and professional standards. Most of our diamonds are certified independently by either the Gemological Institute of America (GIA), the European Gemological Laboratory (EGL) or the American Gem Society (AGS). The certificate gives measurements for the diamond as well as its key characteristics. It also provides a detailed diagram of the diamond's interior.

Each diamond is additionally backed by the strongest guarantee in the business, the Mervis name.

Mervis offers peace of mind, and assures you that you are getting a brilliant, high quality diamond, whatever your price range.
