- HRD is a non-profit
organization at the service of the Belgian diamond trade and
industry. The HRD not only acts as the representative
and mouthpiece of the diamond sector, the various departments
also offer the diamond community a wide range of services.
One of these is the HRD Certificates Department, founded
in 1976 to meet the growing demand for reliable diamond
that time, a large number of diamond laboratories existed.
Concerning nomenclature and grading methods, confusion reigned,
which made it very difficult for the consumer and even for
the professional diamond dealer to judge the value and meaning
of a certificate.
official opening of the Certificate Department was preceded
by extensive research. Already in 1972, a study of polished
diamonds was set up in cooperation with the Antwerp University
(Rijksuniversitair Centrum Antwerpen, RUCA).
HRD was not the only organization to realize the importance
of good quality descriptions being available.
World Federation of Diamond Bourses (WFDB) and the International
Diamond Manufacturers Association (IDMA) also felt that
a clear and well-founded system for grading polished diamonds
was urgently needed.
1975, WFDB and IDMA appointed a Joint Committee to create
an international standard for rules, working methods and
results of the study made in Antwerp and, starting from
1976, the practical experience of the HRD Certificates Department,
significantly contributed to the work of the Committee.
In this way, a comprehensive system of rules and methods
was built up, combining the practical experience of professional
diamond people with scientific facts and figures.
Joint Committee later changed its name to the International
Diamond Council (IDC). In 1978, the IDC presented the result
of all these efforts at the world congress of WFDB and IDMA:
the International Rules for Grading Polished Diamonds.
system was unanimously accepted, and since then the HRD Certificates
Department is working according to these IDC Rules. In the
following years, the system was adopted by other major diamond
HRD Certificates Laboratory has, since its foundation in
1976, grown into one of the largest diamond certification
labs in the world.
