    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.

    EXAMINATION

    When registered in our lab, your diamond or jewellery will be thoroughly examined by our graders and will undergo the following steps:

    WEIGHT

    SCREENING

    MEASUREMENT

    FLUORESCENCE

    COLOUR

    CLARITY

    CUT

    The weight of a diamond is expressed in carats. One carat equals 0.2 grams or 100 points, which indicates the size. HRD Antwerp has extremely accurate scales that measure up to five figures after the decimal point.

    The first step is to determine if your diamond is natural, laboratory-grown or treated. If a diamond does not pass the initial test, it will be directed to our research department to further determine its nature.

    Your diamond is accurately measured in millimetres as mentioned below: minimum diameter – maximum diameter in mm x height in mm (example: 6.44 – 6.47 mm x 4.04 mm)

    The fluorescence grade under long wave is mentioned in the report. For the “Natural Diamond Colour Grading Report” the fluorescence grade under short wave is also mentioned.

    Most diamonds range in colour from colourless (‘D’) to tinted colour (‘Z’). The colour grade is determined by comparison with a series of master stones, the best grade being D.

    All natural diamonds have traces of their growth history, which determines the diamond’s purity. In most gem-quality diamonds, these are minor internal characteristics or inclusions. The very best and rarest stones are graded ‘loupe clean’ or 'LC'.

    A diamond’s cut is essential to its beauty and is a combination of craftsmanship and scientific knowledge. The right proportions, symmetry and polish create internal reflections that maximise a stone’s sparkle, brilliance and fire.

    HEARTS & ARROWS DIAMONDS

    LASER INSCRIPTION

    SEALING

    Hearts & Arrows diamonds are precisely cut round brilliants that, when examined using a special viewer, display eight hearts through the pavilion of the diamond (from below) and eight arrows through the crown of the diamond (from above). The appearance of the pattern is a strong indicator of a top-quality cut.

    o inscribe diamonds with lasers, HRD Antwerp uses high-quality excimer shortwave technology. It cannot be seen with the naked eye and consequently does not affect the diamond’s physical appearance or value. Laser inscription can either be used to match your diamond and its corresponding grading report or to customise your diamond with a personalised message or logo.

    Sealing guarantees that an issued grading report and the corresponding diamond belong together, and it keeps the diamond safe from oil and dirt. The HRD Antwerp sealing is tamper-proof.

    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.
