Detailed explanation of changes
CARLSBAD, Calif. – 1 April 2019 – On 29 March 2019, GIA announced changes to its laboratory-grown diamond grading report to align the report with recent revisions to the US Federal Trade Commission (FTC) Jewelry Guides.
As of 1 July 2019, GIA will discontinue the GIA Synthetic Diamond Grading ReportTM, introduced in January 2007, and introduce the GIA Laboratory-Grown Diamond ReportTM.
- The GIA Laboratory-Grown Diamond Report will include the standard GIA colour, clarity and cut grading scales for reference purposes.
- The GIA Laboratory-Grown Diamond Report will continue to use Colourless, Near Colourless, Faint, Very Faint and Faint to report the colour grades for laboratory-grown diamonds, rather than the letters used to report the colour grades for natural diamonds.
- The standard GIA colour-grading scales will be included on the report for reference, for example: Colourless for D, E and F; Near Colourless for G, H, I and J; and Faint for K, L and M.
- The GIA Laboratory-Grown Diamond Report will continue to use Flawless, Internally Flawless, Very Very Slightly Included, Very Slightly Included, Slightly Included and Included to report the clarity grades for laboratory-grown diamonds, rather than the VVS1 and VVS2; VS1 and VS2; SI1 and SI2; and I1, I2 and I3 grades used to report clarity for natural diamonds.
- The standard GIA clarity-grading scales will be included on the report for reference, for example Slightly Included for SI1 and SI2.
- The GIA Laboratory-Grown Diamond Report will use ‘laboratory-grown’ in the identification line of the report; ‘synthetic’ will not be used in the report.
- The GIA Laboratory-Grown Diamond Report includes the following statement: This is a man-made diamond produced by CVD (Chemical Vapour Deposition) or HPHT (High Pressure High Temperature) growth processes and may include post-growth treatments to change the colour.
- All detected clarity treatments will be disclosed.
- The QR code on the GIA Laboratory-Grown Diamond Report will link to GIA’s online Report Check Service which can be used to confirm that the information on a report matches what is in the GIA report database. The Report Check record for each GIA Laboratory-Grown Diamond Report will include educational material about the CVD and HPHT methods for growing laboratory-grown diamonds to help educate consumers and fulfil our mission of ensuring the public trust in gems and jewellery.
- GIA specifies ‘natural diamond’ on its grading reports for natural diamonds – the GIA Diamond Grading ReportTM and the GIA Diamond DossierTM.
- Any GIA Synthetic Diamond Grading Report issued since 1 Jan 2018, may be returned and exchanged for the GIA Laboratory-Grown Diamond Report at no cost.
