A lot of certified diamonds are laser inscribed. An inscription on a diamond can be found on its girdle and is lasered or burned onto the stone. Laser inscriptions are very small and sometimes are still difficult to view through a 10x magnification loop. In most cases the laser inscription will consist of the name of the laboratory and the Certificate number which is a one off number for that particular diamond. The advantages of purchasing a laser inscribed diamond is that it can always be checked to make sure it matches the certificate number and their for easily identifiable. Most Argyle Diamonds are also laser inscribed for that added bit of security and verification.
