HRD (Hoge Raad voor Diamant)

HRD

The HRD is based in Antwerp, a city with a long tradition of diamond trading. The first diamond exchange was established there in 1893. There are now 28 such exchanges worldwide, four of them in the Belgian port city alone.

The HRD certificates for diamonds

In 1976, the HRD (Hoge Raad voor Diamant) diamond laboratory was founded in Antwerp. This laboratory examines gemstones at a scientific level and issues certificates based on careful analysis procedures. These provide buyers with reliable information about the quality of the diamonds. This is particularly important because the untrained eye of a layperson is far from sufficient to evaluate gemstones . Although basic things can be recognized, such as whether a diamond sparkles fiery or whether it looks rather cloudy and dull, it is simply impossible to determine its exact color or clarity and to recognize whether it is an artificially treated gemstone or a natural one.

The HRD and its field of activity

In addition to the Diamond Lab, the HRD also has a laboratory for colored gemstones (Precious Stone Lab), the aim of which is to acquire scientific knowledge about them and, based on this, to create meaningful certificates.

As part of the Education Department, the HRD offers seminars on various topics related to gemstones, such as ways of identifying or grading quality.

In addition, the HRD is responsible for the distribution of laboratory equipment, which includes, for example, highly specialized microscopes.
