Natural Diamond Grading Report
An HRD Antwerp Natural Diamond Grading 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.
Laboratory Grown Diamond Grading Report
Every diamond is tested to determine whether it is natural. If it is found to be laboratory grown, under disclosed conditions, we will issue a Laboratory Grown Diamond Grading Report, with this clear wording on the cover. Each laboratory grown diamond is laser inscribed with “LAB GROWN” and report number. The presence of the laser inscription is mentioned on the Grading Report, including a reference number and statement that the diamond has been laboratory grown. The same nomenclature as in a Natural Diamond Grading Report is used, with a detailed description of the 4Cs.

This grading report mentions the colour origin of your diamond and describes its colour characteristics, as well as its short- and long-wave luminescence.
