HRD Diamond Certification Explained

The European Diamond Grading Authority

HRD Antwerp is one of Europe’s most established gemological laboratories. Located in Antwerp, Belgium, the institute operates within one of the world’s historic diamond trading centers.

HRD provides diamond grading reports that document the measurable qualities of diamonds using internationally recognized grading methods.

What an HRD Diamond Report Includes

HRD certificates contain information about the diamond’s carat weight, color grade, clarity grade, and proportions. The report also includes measurements describing the diamond’s shape, dimensions, and structural characteristics.

Many HRD reports include diagrams mapping the diamond’s inclusions and identifying surface features. Like other laboratories, the report may also include a unique identification number connected to the diamond.

These reports provide a detailed description of the stone’s physical characteristics.

Where HRD Certification Is Commonly Used

HRD reports are widely used in European diamond markets, particularly within the Antwerp trading community. Because Antwerp has historically been a global hub for diamond trading, HRD reports appear frequently in international inventories.

Buyers researching diamonds may encounter HRD certification when reviewing stones sourced through European markets.
