ZGL Laser Inscription

Only after the first seven steps of the grading process have been completed is the diamond sent for laser inscription. If a Diamond Précis was ordered for the diamond, it will have the identification number laser-inscribed on its girdle. The inscription number is the same as the ID number on the diamond’s certificate. For a small additional fee, diamonds receiving an ZGL Diamond Grading certificate may also have their ID number laser inscribed on the its girdle. Additionally, all diamonds may receive an inscription of a specific brand or company name or a personal message for the customer. (This service is considered as extra service and not include in the ZGL basic grading service pack.)
