HRD Antwerp NV operates six divisions: Diamond Lab (which issues one of the world’s most respected diamond certificates), Education, Graduates Club, Precious Stones Lab, Equipment and Research.

Diamond Lab
Demand for diamond grading reports has grown dramatically in recent years, as consumers increasingly demand independent and concrete documentation of their purchases. Based on this growing demand worldwide, HRD Antwerp has opened representative offices in Mumbai, Shanghai and Hong Kong. It also launched HRD Antwerp Lab Link, a diamond grading and certification pick-up and drop off service in Tel Aviv, Hong Kong, Mumbai and Dubai.
HRD Antwerp Lab Link offers a full service for customers who like to receive a HRD Antwerp certificate for their diamonds. The service guarantees that diamonds are picked up by a professional logistic company and sent to Antwerp. Within 15 days, the customer receives back his diamond with an HRD Antwerp diamond certificate. This service is offered at very competitive prices.
HRD Antwerp diamond certificate guarantees that the stone examined is indeed a real diamond, and contains a full and detailed quality description, focussing on the famous 4C’s – Carat (weight), Colour, Clarity and Cut. The report includes a complete quality description of the diamond including shape, weight, clarity grade, fluorescence, colour grade, possibly supplemented with comments.
The HRD Antwerp Diamond Lab is the largest diamond grading organisation worldwide to confirm to the standards of the International Diamond Council, by the World Federation of Diamond Bourses and the International Diamond Manufacturers Association, the industry’s two leading representative bodies.
The Diamond Lab was also the first diamond lab ever to receive accreditation by the International Standards Organisation, and currently operates according to the demanding standards of NBN EN ISO/IEC 17025.
Underpinning the work at the lab is the Research Department. Located at a dedicated facility in the nearby town of Lier, the institute has a team of scientists, engineers and laboratory staff carrying out research into diamond properties, as well as applied research to assist the diamond industry and to provide specialized services to the sector. One of these new services is called ‘Hearts and Arrows by HRD Antwerp’. Hearts and Arrows diamonds (H&A) are round brilliants with special patterns visible under specific lighting conditions. They consist of eight hearts when viewed from the pavilion side and eight arrows when viewed from the crown side. The appearance of the pattern is a strong indicator of a top quality cut. HRD Antwerp ordered a research project to solve several problems linked with grading this pattern.
Today companies can ask for such an HRD certificate for a diamond. With objective criteria and digital imaging is determined whether a diamond meets the Hearts & Arrows standard. At the same time, diamond professionals receive accurate and repeatable feedback to assist them in the manufacturing and sales process.
