GIA Takes Strong Action with Counterfeit Reports



The Gemological Institute of America was recently notified of three counterfeit grading reports that accompanied diamonds weighing 3.00 cts., 4.08 cts., and 5.01 cts., sold to a client in Johannesburg, South Africa.

After further investigation, it was found that not only were the reports fraudulent, but at least one of the accompanying diamonds was also high pressure/high temperature treated. Follow-up testing is being done for the other two diamonds.

The problem is not believed to be widespread and is limited to a small number of stones.

GIA, working in collaboration with the client and industry leadership in South Africa, funded private investigations that led to the arrest of one individual.

GIA provides a number of services to safeguard against the misrepresentation of a diamond and its report. For GIA diamond grading reports and GIA Diamond Dossiers® issued since Jan. 1, 2000, GIA Report Check is a free online service that lets customers confirm that the information contained in a report matches the data contained in GIA’s database.
