HRD Diamond Certification
Origins
HRD, which stands for Hoge Raad voor Diamant, or "Diamond High Council," officially represents the Belgian diamond sector at home and abroad. Established in Antwerp in 1973, HRD is a multifaceted organization. Among its many departments are HRD Certificates, which meets the growing demand for diamond certifications, and HRD Research, which delivers technological support to the diamond industry. HRD is one of the world’s most respected diamond institutes, and a great deal of pride is attached to each diamond that earns the HRD seal of approval.
HRD Diamond Certificate
Methodology
The HRD Certificates Department issues diamond quality reports based on international standards. To ensure that HRD diamond grading is completely fair and unbiased, the identities of diamond owners who submit stones for HRD certification are never revealed to the lab’s gemologists. To further safeguard quality and consistency, senior gemologists randomly check grading results on a daily basis.
- Several gemologists analyze each diamond, assigning grades for weight, color, clarity, and cut.
- The number of graders utilized increases relative to the size of the diamond.
- Each grader gives his quotation with no knowledge of other graders’ judgments.
- A final grade is assigned only on the basis of a sufficient number of identical quotations.
