GIA Introduces New Diamond Country of Origin Reports

Confirmation through analytical testing for eligible diamonds

CARLSBAD, Calif. – March 28, 2019 – On April 30, GIA will introduce the GIA Diamond Origin Report service which will confirm the country of origin of polished diamonds. To be eligible for this new service, the original rough diamonds and resulting polished diamonds must be submitted to GIA for analysis so that they can be matched to each other and to confirm the origin information provided by the participating mining company. The new report will include the country of origin, a full 4Cs quality analysis of each diamond and a report number inscription. More information about the country of origin and diamond formation will be available for each Diamond Origin Report in GIA’s online Report Check service, accessible at or through the QR code printed on each report.
