Diamond Sealing

Diamond Sealing is the ultimate security tool and ensures complete transparency and assurance of a diamond vis-à-vis the colour, clarity and cut grade.

It is a great sales tool to promote genuine certified diamonds. The diamond seal is a tamper proof pack and thus prevents any attempted replacement of its contents.

Sealing guarantees that a given certificate and the corresponding diamond belong together. It provides a consistent, categorical connection between the diamond and its certificate.

The purpose of this special diamond seal is to make it undoubtedly certain that the contained stone is the one actually reported in the certificate. The SGL Diamond 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’.
