Dear GIA Laboratory Client,
The revised GIA laboratory services for D-to-Z laboratory-grown diamonds will launch on October 1. Current GIA laboratory services for D-to-Z laboratory-grown diamonds will be available until September 30. This update to our services was announced in a GIA press release on June 2.
These changes to our service reflect changes in the production of laboratory-grown diamonds. Most diamonds entering the market fall into a very narrow range of color and clarity. Therefore, it is no longer appropriate for GIA to use the terms developed to describe the broad range of color and clarity found in natural diamonds to describe the quality of a manufactured product.
The GIA Laboratory-Grown Diamond Quality Assessment will use descriptive terms rather than the GIA-developed nomenclature for natural diamonds. The laboratory-grown diamonds will be described as ‘Premium’ or ‘Standard’ based on an overall assessment of their clarity, color and cut.
Laboratory-grown diamonds that meet all the following criteria will be classified as ‘Premium.’
Clarity – Very, Very Slightly included and higher
Color – D
Polish, symmetry - Excellent
Cut grade – Excellent (round brilliant cut diamonds only)
Laboratory-grown diamonds that meet any combination of the ‘Premium’ criteria and the following criteria will be classified as ‘Standard.’
Clarity – Very Slightly included
Color – E-to-J
Polish – Very Good
Symmetry – Very Good (or Good for fancy shapes only)
Cut grade – Very Good (round brilliant cut diamonds only)
Any diamond that does not meet all the minimum criteria for ‘Standard’ will not receive a GIA assessment.
The fee for GIA Laboratory-Grown Diamond Quality Assessment is US$15 per carat, with a minimum of fee of US$15. Submissions that do not meet the minimum criteria for assessment will be charged a US$5 evaluation fee. The minimum size for submission is 0.15 carats. Each submitted stone’s girdle will be laser inscribed with the term “Laboratory-Grown” and the GIA quality assessment number. A printed document with the assessment results will be returned with each laboratory-grown diamond.
