HRD Antwerp's primary shareholder is the Antwerp World Diamond Centre (AWDC). The AWDC is a private foundation established in 1973 as the Hoge Raad voor Diamant (HRD) or Diamond High Council and represents the Belgian diamond industry.
The HRD Antwerp diamond lab is the largest diamond lab in the world that issues reliable diamond grading and jewellery reports fully compliant with the rules for grading polished diamonds set by the International Diamond Council (IDC). We are the only international lab that strictly adheres to these rules, which have been approved by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA), the industry's two leading representative bodies.
Quality that inspires confidence
The integrity of the HRD Antwerp grading process is absolute. Our diamond lab applies an uncompromising operating code which it supports by using some of the most sophisticated technology and qualified graders available. HRD Antwerp's extensive in-house research department makes sure all processes are updated according to the latest industry developments.
Strict anonymity and objectivity
The absolute objectivity of the grading results is guaranteed by means of a double coding system: one set of codes is given to the owner, while the other follows the diamond in the lab. Strict anonymity guarantees strict objectivity.
