Natural Diamond Grading Report

An HRD Antwerp Natural Diamond Report is an objective report that confirms a polished natural diamond’s authenticity and provides a detailed description of its key characteristics, the so-called 4Cs: Carat, Colour, Clarity and Cut.

Quality that inspires confidence
The integrity of the HRD Antwerp grading process is absolute. Our diamond lab applies an uncompromising operating code which it supports by using some of the most sophisticated technology and qualified graders available. HRD Antwerp's extensive in-house research department makes sure all processes are updated according to the latest industry developments.

Strict anonymity and objectivity
The absolute objectivity of the grading results is guaranteed by means of a double coding system: one set of codes is given to the owner, while the other follows the diamond in the lab. Strict anonymity guarantees strict objectivity.
