Why HRD Antwerp Is Respected Across Europe

HRD adheres strictly to the rules of the International Diamond Council (IDC). This organization was formed by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA).

IDC Strict Clarity Limits

HRD uses the "Loupe Clean" designation alongside IF/VVS grades and employs strict European microscopy rules when plotting internal inclusions.

Full Lab-Grown Identification

HRD tests every diamond with proprietary D-Screen and M-Screen spectrometers to immediately isolate CVD/HPHT lab diamonds and inscribe "LAB GROWN" on the report and girdle.

Anti-Counterfeiting Security

Physical HRD reports incorporate UV-reactive watermarks, micro-printing, and metallic holograms that cannot be reproduced by standard commercial scanners.
