Additional services

MY HRD Antwerp 
A secure 24/7 online service that gives you access to your diamond's grading results and allows you to provide further instructions online.

Transit is what we call the grading of certain of your diamond's characteristics. When your diamond enters the so called transit zone, you can check its results online.

For more info, check the MY HRD Antwerp manual.

MY HRD Antwerp

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.

Hearts and arrows

To laser inscribe diamonds, HRD Antwerp uses high-quality excimer short-wave 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 personal message or logo.

Laser inscription

Sealing guarantees that a given 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. Watch for:

  • Disruptions of the wavy blue pattern.
  • Fractured red electrostatic bars.
  • The crypto-printed words 'SAFETY SEAL ANNULLED' and 'VOID'.
