Aussie lab issues laser-inscription alert

Sydney, Australia—The Diamond Certification Laboratory of Australia (DCLA) issued a trade alert regarding an unidentified lab in Melbourne, Australia, that is allegedly "hot" laser-inscribing diamonds that have been certified by other laboratories before checking if the diamond and certificate match.

According to the DCLA, the correct practice is for the diamond to be inscribed with the name and/or logo of the lab, a certificate number and discretionary text before a certificate is issued.

By hot laser-inscribing a diamond after it has been certified by the DCLA, the lab stated that the certificate in question would be void because the properties of the diamond may have been altered.

The alert also warns of potential fraud related to the change in the grade of a diamond and asked members of the trade who suspect they have a hot laser-inscribed stone to contact the lab.
