We authenticate your solitaire diamond purchase with a detailed grading report. It guarantees the authenticity (that the diamond is natural) and uniqueness of the diamond. The grading report consists of three international certificates that belong to that specific piece of jewellery:

• A GIA Diamond Report (from the Gemological Institute of America)
• A IGI Diamond Report (from the International Gemological Institute)
• An HRD diamond report (from Hoge Raad voor Diamant meaning the Diamond High Council)

The report is unique, irreplaceable and must always follow the diamond. The report comes wrapped in an envelope with your solitaire diamond jewellery.

In addition to this detailed report, all diamonds above 0.30 ct. come with an OLE LYNGGAARD COPENHAGEN certificate made by our diamond supplier in Denmark.
