Reports it publishes

Named as the laboratory names them on its own site. Report contents and wording are set by the laboratory, not by us.

Worth knowing

Founded in 1973 as the Hoge Raad voor Diamant, the Diamond High Council, which was split in 2007 into AWDC and HRD Antwerp. The Natural Diamond Colour Grading Report states colour origin in the sense of natural versus treated colour, which is not geographic origin. Report lookup runs through the my.hrdantwerp.com client portal rather than an open public page.

We verify dealers, not stones. A laboratory report describes one stone on one date; it is not a guarantee of value, and it is not ours to stand behind.
