The International Gemological Institute (IGI) recently analyzed and graded a 6.18 carat round brilliant-cut stone submitted for grading as a natural diamond, then identified as a lab-grown diamond. The stone was sent for verification purposes and came with a report from the Gemological Institute of America (GIA) stating it was a natural diamond, D color, flawless clarity, and triple-excellent cut, reinforcing the growing importance of secondary review from gemological institutes.
Citing recognition of the Gemological Institute of America (GIA) for gemological report services and education, a Belgian court has ordered AIG Belgium to immediately cease using ‘AIG’ alone or in conjunction with other marks. AIG operated as both the American International Gemological Laboratories and Antwerp International Gemological Laboratories. If the lab fails to do so, they risk significant penalty payments.
GIA recently discovered a number of diamonds, submitted at GIA for an update on their grading report, for which the characteristics did not correspond with the grading of the certificate. All stones turned out to be either LGD or treated natural diamonds with a counterfeit laserinscription on the girdle, while the original certificates all belonged to natural, untreated diamonds.
GIA has launched the earlier announced new grading reports for lab-grown diamonds, LGDR by GIA, a range of four digital reports in which the descriptive terms and grade ranges are now replaced with 4C color and clarity specs, described using the same scale GIA uses for natural diamonds. In terms of look and feel, the LGDR, digital only reports differ from the classic GIA natural grading reports and each stone will be inscribed with a report number and the words "Laboratory-grown", the GIA adds in a press release.
The Gemological Institute of America and IBM Research today announced they are partnering to develop an advanced artificial intelligence system, based on data from tens of millions of stones graded by GIA, to grade one of the diamond "4C's", clarity. The partnership is another step in GIA's move into digital transformation of its grading operations. The system, currently deployed in the NY and Carlsbad GIA labs initially focuses on the most popular sizes and cuts, but will gradually be scaled up to more sizes, shapes and qualities, the statement reads.
As many countries are easing out of strict quarantaine, GIA has announced it has reopened its labs in Antwerp, Carlsbad, Gaborone, Johannesburg and Tokyo, each with modified schedules. In Antwerp and Johannesburg, visitors are welcome by appointment, in Tokyo, Carlsbad and Gaborone, the labs will only accept submissions via shipment.
"Effective immediately, GIA [Gemological Institute of America] will suspend diamond sealing services," the organization said in press release last Friday. The statement continues, "The Institute is taking this action after recently encountering a small number of GIA sealing packets that had been compromised by third parties after the sealing packets left GIA." The organization discovered "that the diamonds originally enclosed in the compromised packets had been replaced with HPHT (high-pressure, high-temperature) treated natural diamonds."
The Gemological Institute of America (GIA) has added a third ad that will run on Times Square running up to Valentine's Day, promoting their Diamond Origin Report. Launched in 2019, the GIA Diamond Origin Report uses scientific evaluation to match a polished diamond to its original rough, providing confirmation of the origin information provided by the diamond mining company and including information that helps consumers understand the positive social and economic impact that mined diamonds have for the countries and communities that produce them.
The Gemological Institute of America (GIA) is set to close its operations in Dubai. According to sources, the GIA is making the move to ensure they use their resources as effectively as possible to fulfil their consumer protection mission, and will close its Dubai office by the end of the year. The renowned diamond grading and certification lab most recently started operations at a new facility in Antwerp.
In early 2019, the GIA (Gemological Institute of America) prodvided an update on two pilot projects to distribute an illustrated booklet, “Selecting Gem Rough: A Guide for Artisanal Miners,” which was created to help small-scale miners learn more about the quality and classification of the gems they recover, and ultimately to help them obtain greater market value.
Researchers at the Gemological Institute of America (GIA) recently identified a natural diamond with a CVD (lab-grown) layer, creating a composite of synthetically grown and natural diamond that added weight and improved the color. Given that this was the second discovery of such a composite, the fist coming in 2017, warning that "this could be a new type of product entering the market."
The Gemological Institute of America (GIA) is enhancing its ‘Know Your Customer’ (KYC) program.

Russian diamond miner Alrosa has mentioned several times recently that it is aiming to become the leader in the international market for colored diamonds, and is making its case with a media preview of its collection of large colored diamonds, including unique pink, bright yellow and pink purple gems. The star of the show was a pink oval diamond weighing 14.83 carats - the largest pink diamond in the history of Russia.
The GIA (Gemological Institute of America) has developed an illustrated booklet, “Selecting Gem Rough: A Guide for Artisanal Miners,” to help small-scale miners learn more about the quality and classification of the gems they recover, and ultimately to obtain greater market value. As Russel Shor explains, the two pilot projects GIA initiated with Pact, a Washington, D.C.-based non-governmental development organization with offices in Tanzania, are having an impact on these miners' lives.

GIA says it has already secured premises for both locations. In Antwerp, GIA will be occupying space in the Antwerp Diamond Bourse.
The latest fraudulent twist on the synthetic diamond landscape has profound implications for the efforts to keep natural and synthetic diamonds separate, if the incident in question is not an isolated one. The Gemological Institute of America (GIA) recently recieved a round brilliant cut diamond (image, left) submitted for an updated diamond grading report. Its girdle was inscribed with an actual GIA report number (image, right), identifying the stone as a natural, untreated diamond. After testing, however, it turned out that the newly submitted diamond was an HPHT-grown synthetic diamond.
The largest-ever D-flawless diamond to be put up for auction, mounted in a diamond and emerald necklace, sold for $33.7 million Tuesday night, including buyer’s fees. The white “Creation 1” diamond from Swiss jeweler de Grisogono weighs 163 carats. The hammer went down at 29.5 million Swiss francs ($29.7 million), excluding the buyer’s premium — around the midpoint of the pre-sale estimates before the auction at Christie’s in Geneva. The buyer was not immediately identified.

The Gemological Institute of America (GIA) launched a new service which tracks the origin of a selection of polished diamonds, which offers retailers a new method of being able to uncover a stone’s history. Since the project is only two years in development, GIA's M2M™ (Mine to Market) program is restricted and is not yet able to provide a complete solution to determining a diamond’s provenance. “If you just gave me any polished diamond, I can’t tell you what mine it came from,” says Matt Crimmin, GIA’s vice president of laboratory operations.
The Gemological Institute of America (GIA) has made an alarming discovery, namely, a natural white diamond covered by a thin (80 microns, or 0.003 inches) synthetic layer that colors it blue – and has warned that more such composites might be on the market. The 0.33-carat stone is a composite of CVD synthetic Type IIb diamond overgrowth on a natural Type Ia diamond.
In April 2017, a symposium called, “Synthetic Diamonds: Are Watchmaking and Jewelry in Danger?” was held in Geneva, specifically to address the issue of synthetic diamonds in the domain of watchmaking and how it is possible to differentiate natural from lab-grown stones.
Some interesting industry developments took shape at last week's Diamond Detection Expo and Symposium sponsored by India's Gem and Jewellery Export Promotion Council (GJEPC).
