The Gemological Institute of America (GIA) adds natural coloured diamonds to its Diamond Origin Report service. To obtain a Diamond Origin Report, companies have to submit both a rough and polished stone to GIA. Physical measurements and scientific data will be used to compare the two stones. If the data from the polished matches with the rough, GIA will include the information on the Diamond Origin Report.
Other than the country of origin, a full 4Cs quality analysis and a report number inscription will be included as practice. Details on the country of origin and diamond formation will be available in GIA’s online report check service, accessible at its official website or through the QR code printed on each report.
The Diamond Origin Report was launched on 30 April after discussions with mining companies, manufacturers and retailers regarding their traceability needs, and conducted consumer research, which showed that 69 percent of U.S. bridal customers prefer a diamond with an origin story.
