Founded in 1976 to meet the growing demand for reliable diamond certificates, the HRD is a non-profit organisation at the service of the Belgian diamond trade and industry. Since its foundation in 1976, the HRD Certificates Laboratory has expanded into one of the largest diamond certification labs in the world and maintains an excellent reputation for quality and objectivity.
Each diamond is examined independently by several experts with very sophisticated machinery, such as spectophotometres, Dia-Mention systems, and cathode luminescence apparatus to ensure a high level of reliability.
