Diamond laser inscription is becoming more and more popular as customers appreciate the benefits of having certificate numbers inscribed onto the girdle of each stone.
This inscription adds credibility to the certificate and, in practical terms, is the only certain way to avoid certificates and diamonds becoming mixed up.
The laser machine at The Birmingham Assay Office is also in regular use adding weights, personal messages, and logos to differentiate products and add value.
Diamonds can be inscribed when they are loose or mounted, just so long as there is space for the laser to make contact with the girdle.
