The HRD Diamond Certificate



The H.R.D. (Hoge Raad voor Diamant or Diamond High Council), was founded in 1973 and is a government owned body which is affiliated to the University of Antwerp.

It is a non-profit organisation and is the only officially recognized representative of the Belgian diamond trade and industry.

HRD headquarters are located in Antwerp, Belgium, World Diamond Center.

The HRD certificate enjoys an excellent reputation for objectivity and quality. The objectivity of the grading results is guaranteed by preserving the strictest anonymity. When a diamond is brought in for examination at the reception of the Certificates Department, all data are introduced into the computer. The stone then receives two numbers: an external number for use of the client, which is printed on the receipt note, and an internal number to follow the stone in the lab. The graders who perform the examination never know to whom a stone belongs, which is a guarantee of absolute objectivity.
