GIA aligns gem reports with FTC guides

1 April 2019

Information shown on a GIA Laboratory-Grown Diamond Report


The Gemological Institute of America (GIA) has revised its education materials and updated its grading reports for laboratory-grown diamonds to align with the Federal Trade Commission’s (FTC) revised Jewelry Guides.

Beginning July 1 this year, GIA Laboratory-Grown Diamond ReportsTM and identification reports will no longer use the term “synthetic.”

The new GIA Laboratory-Grown Diamond Report will feature the same visual representation of the scales for colour, clarity and cut as GIA’s grading reports for natural diamonds. The updated reports will continue to use descriptive terms for colour and clarity, for example, Near Colorless and Very Slightly Included, as shown on the scales. The report will also include a QR code linking to GIA’s online Report Check service with more information about the growth processes of laboratory-grown diamonds. All detected clarity treatments will be disclosed. The comments section will include the statement: This is a man-made diamond produced by CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) growth processes and may include post-growth treatments to change the colour. 

Any GIA Synthetic Diamond Report issued since January 1, 2018, may be returned and exchanged for the new Laboratory-Grown Diamond Report at no cost.

Since the FTC revision in July 2018, GIA said it had been reviewing and revising its education materials and procedures to ensure consistency in nomenclature across the Institute. Research conducted by GIA showed that consumer focus groups indicate that there is still confusion about the product and the differences between natural and laboratory-grown diamonds.

In another development, GIA said it will introduce on April 30 the GIA Diamond Origin Report service, which will confirm the country of origin of polished diamonds. The new report will include the country of origin, a full 4Cs quality analysis of each diamond and a report number inscription.

GIA also revealed that it engaged with mining companies, manufacturers and retailers to identify their traceability needs and conducted consumer research, which showed that 69 percent of US bridal consumers prefer to buy a diamond with an origin story.
