Europe's authority on diamond grading and jewellery.
A single standard, held for six centuries.
HRD Antwerp stands as Europe’s leading authority in diamond grading, jewellery grading and education. We grade. We report. We educate — with a rigour that has made Antwerp the reference point of the diamond world.
Every stone that enters our laboratory is treated with the same scientific discipline, whether it is a single brilliant or a parcel of a thousand. That consistency is what the trade means when it says a diamond is “HRD-graded”.
Three pillars, one methodology.
Grading and laboratory services, gemmological education, and the instruments the trade relies on — each built and audited to the HRD standard.
Grading & lab services
Independent grading reports on cut, colour, clarity and carat — recognised across the global trade.
Education
Gemmological courses and seminars, from rough-to-brilliance fundamentals through to advanced grading.
Shop equipment
Microscopes, lamps and consumables — the same instruments used in our own laboratory.
An intro to grading and the HRD process.
From the moment a diamond enters our lab to the issuing of its grading report, every step is documented, sealed and verifiable. This is the process that underpins six centuries of trust.
Diamonds enter, are verified, repackaged and weighed under seal.
The 4Cs — Carat, Cut, Clarity, Colour — assessed by independent gemmologists.
Laser inscription, sealing and repolishing on request.
Where the next generation learns the trade.
HRD Antwerp Education trains gemmologists in Antwerp, Mumbai, Dubai and online — teaching the very standards we apply in the laboratory. A dedicated education platform is on its way.

“An HRD grading report is the closest thing our trade has to an absolute reference. It is the number our clients trust without question.”
“We send every important stone to Antwerp. The consistency of the grading, report after report, is what protects our name.”
“The education I received at HRD changed how I see a diamond. I grade differently — and better — because of it.”
