Certificate of authenticity

This document is as important for a diamond as a birth certificate for a person or an entry in the real estate registry for a family house. It records the unique properties of the gemstone, size, color and other characteristics. The certificate also verifies that the diamond was obtained legally.



In addition, for diamonds weighing more than one carat, you will also receive a certificate of authenticity from an independent international gemological laboratory in the United States, G.I.A. - one of the most recognized gemological institutions in the world, HRD (Hoge Raad voor Diamant - Diamond Council), EGL USA (European Gemological Laboratory of the United States of America) or IGI (International Gemological Institute).
