Beginning at the end of 2025, GIA willInstead, GIA will implement a new descriptive grading system that lab-grown diamonds submitted to GIA will receive simplified descriptors—categorized broadly as either "premium" or "standard" or no grade at all if the quality is subpar.

As a non-profit organization, GIA emphasizes the fundamental differences between the two, including their formation processes, physical characteristics, and market values. According to Tom Moses, GIA Executive Vice President and Chief Laboratory and Research Officer, "More than 95% of lab-grown diamonds entering the market fall into a very narrow range of color and clarity. Because of that, it is no longer relevant for GIA to describe man-made diamonds using the nomenclature created for the continuum of color and clarity of natural diamonds."This revision of grading standards is another milestone following GIA's abandonment of the term "Synthetic" and its move to describe lab-grown diamonds in relation to natural diamond standards. GIA created the 4Cs—cut, colour, clarity, and carat weight—as a rigorous system to help consumers understand the unique and qualities of natural diamonds. With the new lab-grown diamond grading system, the core value of natural diamonds—rarity and emotional attributes are further two natural diamonds are exactly alike.

GIA not to use 4C system to grade lab-grown diamonds
The Gemological Institute of America (GIA), considered the world's foremost authority on gemmology, said later this year, it will start using descriptive terms to characterise the quality of laboratory-grown diamonds and no longer use colour and clarity nomenclature it had developed for natural diamonds and been in use since 1953. It means GIA will drop its traditional 4Cs (Colour, Clarity, Cut & Carat Weight) diamond grading system for lab-grown diamonds to ensure clear demarcation between natural and man-made diamonds. Later this year, lab-grown diamonds handed over to GIA will receive simplified descriptors—categorised broadly as either 'premium' or 'standard'— or no grade at all if the quality is subpar. The institute said it would continue to accept laboratory-grown diamonds for evaluation and identification. 'Similar to other man-made gem materials, we anticipate the continued acceptance and popularity of laboratory-grown diamonds,' said Tom Moses, GIA executive vice-president and chief laboratory and research officer in a statement. Amit Pratihari, Managing Director, De Beers India said, 'GIA's decision is a timely and important move that brings much-needed clarity to consumers. 'It reinforces the fundamental differences between natural diamonds and lab-grown — not just in origin, but in emotional and enduring value. We have always maintained that natural diamonds are rare, billions of years old, and deeply symbolic — a fact that resonates strongly with Indian consumers,' he said. Kirit Bhansali, Chairman, Gem & Jewellery Export Promotion Council (GJEPC) said, 'This change will help eliminate confusion by clearly distinguishing how lab-grown diamonds are assessed, separate from the standards developed for natural diamonds.' 'For consumers, it brings greater transparency and ensures that purchasing decisions are based on a clear understanding of a diamond's origin and characteristics,' he said. 'For India, as a leading hub for both natural and lab-grown diamonds, this change brings much-needed clarity and balance to the marketplace — allowing both categories to grow with greater transparency, integrity, and consumer confidence,' he added.

GIA to introduce new descriptive grading system for lab-grown diamonds, phasing out traditional 4Cs
Beginning later this year, GIA (the Gemological Institute of America ) will start using descriptive terms to characterise the quality of laboratory-grown diamonds (LGDs) and will no longer use the colour and clarity nomenclature that GIA developed for natural diamonds. The Indian diamond trade said that for consumers, it brings greater transparency and ensures that purchasing decisions are based on a clear understanding of a diamond's origin and characteristics. The Institute will continue to accept laboratory-grown diamonds for evaluation and identification. The revised GIA description system for laboratory-grown diamonds will confirm that the submitted item is a laboratory-grown diamond and whether it falls into one of two categories, 'premium' or 'standard.' The categories will be defined by a combination of metrics related to colour, clarity and finish. If the man-made diamond fails to achieve the minimum standard for quality, it will not receive a designation from GIA. Until the revised descriptive system for laboratory-grown diamonds is finalised, the current GIA services for laboratory-grown diamonds will continue to be available. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Play this game for 3 minutes, if you own a mouse Undo 'Similar to other man-made gem materials, we anticipate the continued acceptance and popularity of laboratory-grown diamonds,' said Tom Moses, GIA executive vice president and chief laboratory and research officer.

Commenting on GIA's decision, Kirit Bhansali, chairman of Gem & Jewellery Export Promotion Council, said, 'GIA's decision to use descriptive terms instead of the famous 4Cs grading for laboratory-grown diamonds marks an important evolution in diamond classification. This change will help eliminate confusion by clearly distinguishing how lab-grown diamonds are assessed, separate from the standards developed for natural diamonds. For consumers, it brings greater transparency and ensures that purchasing decisions are based on a clear understanding of a diamond's origin and characteristics. For India, as a leading hub for both natural and lab-grown diamonds, this change brings much-needed clarity and balance to the marketplace, allowing both categories to grow with greater transparency, integrity, and consumer confidence.' Live Events GIA developed the universally accepted colour and clarity scales for natural diamonds in the 1940s to communicate their characteristics and reduce consumer confusion. This change to how GIA describes the quality of laboratory-grown diamonds will help consumers understand the important differences in the two products' origin, ensuring their confidence and enabling them to make informed and educated purchase decisions. Pricing and submission guidelines for the revised GIA service for laboratory-grown diamonds are in development and will be announced late in the third quarter. Existing GIA reports for laboratory-grown diamonds remain valid, a release issued by the institute said.
