Downturn Forces GIA to Close Israel Lab

GIA is to close its lab in Ramat Gan, Israel, saying it is no longer “financially sustainable”.

The facility, which opened in August 2012, will close by the end of this year. Submissions will be sent to GIA labs elsewhere, with no additional shipping costs, the lab said in a press statement.

GIA was not able to say at this stage which other labs it would use (Dubai is the closest), or how much extra time that would take.

“Despite reductions in operating costs and reduced staffing through attrition, the laboratory is not financially sustainable,” said GIA, which grades the majority of the world’s polished diamonds.

“The GIA laboratory in Ramat Gan, Israel, will end operations by the end of 2024 due to changes in the global diamond industry that resulted in significant declines in submissions from local clients over the last several years.”

GIA closed its Antwerp lab in July 2022, citing “limited demand for services and financial performance that did not support continued operations”.

It also has labs in Bangkok, Hong Kong, Mumbai, Surat, Tokyo, Carlsbad, New York, Dubai, Gaborone and Johannesburg, according to its website.

From 17 November submissions to the Ramat Gan laboratory will be sent elsewhere. “GIA is working to establish a third-party process to accept submissions from walk-in clients in Ramat Gan for service in other GIA laboratories,” the lab said.

GIA Helps in Recovery of Stolen Diamonds Worth Nearly $475K

The Gemological Institute of America (GIA) identified two diamonds, each over 4 carats, that had been stolen from a home in Colorado.

The stones were taken together with four other pieces of jewelry in June 2023, the GIA said Monday. The combined total of all six pieces is over $475,000.

A wholesale diamond dealer, who was uninvolved in the crime, sent the diamonds to the GIA for grading. When the GIA matched the stones to their reports, it found they had been reported stolen, and alerted detectives from the Boulder County Sherriff’s Office (BCSO), who were then able to use that information to make an arrest in the case, the institute explained.

“GIA often receives requests from law enforcement to help them recover GIA-graded diamonds that are reported lost or stolen,” said Christina Yates, associate general counsel responsible for this aspect of GIA’s work with law enforcement.

The GIA has trained agents with the Federal Bureau of Investigation (FBI), Customs Service and the Federal Trade Commission (FTC), in multiple countries, including the US, Canada, the UK, Belgium, Dubai, Israel and Hong Kong.

GIA Lays Off 151 Employees at Carlsbad Headquarters

 

The Gemological Institute of America (GIA) has cut some 20% of the workforce at its Carlsbad, California, headquarters amid a prolonged slowdown in the industry.

In late July, the lab let 151 employees go, primarily in its laboratory, as well as some in corporate positions, Stephen Morisseau, the GIA’s director of communications, told Rapaport News Sunday. The lab made the layoffs as a result of a drop in the number of diamonds submitted for grading.

“Many organizations in the global gem and jewelry sector are experiencing a downturn due to economic conditions affecting the global gem trade,” Morisseau explained. “Due to those economic conditions, there has been a decline in demand for GIA’s gem identification and grading services, which led to the difficult decision to reduce staffing.”

The layoffs will bring the GIA’s total workforce in Carlsbad to 600, according to The San Diego Union-Tribune, which was the first to report the story. Globally, the lab has approximately 3,500 employees.

“The reductions will not affect our ability to advance our important consumer-protection mission, nor to meet the needs of our clients,” Morisseau added.

Diamond Trade Pressures GIA to Rethink Digital Dossiers

Gemological Institute of America

Diamond dealers and manufacturers have complained to the Gemological Institute of America (GIA) about its new paperless dossier reports, claiming they reduce security and are less popular among retailers.

The reports — available for 0.15- to 1.99-carat, D- to Z-color diamonds — have caused consternation in the industry since the GIA switched to digital-only versions at the beginning of this year.

GIA customers who submit a diamond receive the stone back in a small envelope that shows the key specifications and a unique QR code that links to an online report. Although the girdle gets inscribed, other people can easily copy the code and associate it with a different diamond, according to traders who spoke with Rapaport News in recent weeks.

Suppliers are also seeing pushback from retailers that are accustomed to selling diamonds and jewelry with physical certificates. Using the digital documents is especially difficult with mounted jewelry, an official in the Indian diamond industry noted, as reading the girdle is difficult or impossible.

“In January, they started doing this digital certification,” he told Rapaport News last week on condition of anonymity. “By now, some of the retailers are getting the stones and they’re having concerns, and customers are returning stones that don’t have a [paper] certificate.”

India’s Gem & Jewellery Export Promotion Council (GJEPC) and the Bharat Diamond Bourse (BDB) in Mumbai have raised the issue with the GIA. A representative of the GIA fielded questions from members at the Diamond Dealers Club in New York in a recent address, while delegates discussed the matter at the World Diamond Congress, the triennial meeting of the World Federation of Diamond Bourses (WFDB), which took place in Israel last week.

“Concerns were expressed as to the security of the digital certificates as well as the desire of retailers and consumers to receive a printed certificate,” a WFDB spokesperson told Rapaport News on Sunday. “It was discussed that for a certain period of time, the GIA might provide both digital and printed certificates to those who request them. The presidents of the bourses who participated in the congress asked the WFDB to present their concerns to the GIA.”

A GIA spokesperson said the organization had “heard from clients — manufacturers, brokers, dealers and retailers — about their concerns regarding the digital GIA diamond dossier reports and how integrating the digital reports into their processes could disrupt their businesses.”

“We appreciate the constructive feedback and are considering how we can best address their concerns within the context of our mission to protect consumers and ensure their trust in gems and jewelry.”

The switch to digital dossiers is part of a plan to make all GIA reports paperless by 2025.

GIA Launches The Digital Diamond Dossier

                 Digital GIA Diamond Dossier

The start of 2023 marks a significant milestone in the digital transformation of the global diamond industry – the launch of the fully digital GIA Diamond Dossier, the most widely available diamond grading report in the world. The GIA Diamond Dossier is available for D-to-Z diamonds from 0.15 to 1.99 carats without colour treatments. Printed GIA Diamond Dossier reports issued before January 2023 remain valid.

Tom Moses, GIA Executive Vice President and Chief Laboratory and Research Officer, said, “The launch of the digital GIA Diamond Dossier report starts the conversion of all GIA’s laboratory reports to a modern digital format. This important change improves data security, offers efficiencies across the supply chain and reduces our reliance on paper.”

The first digital GIA Diamond Dossier report was issued at the GIA laboratory in Ramat Gan, Israel, on Monday, 2nd January 2023. More than 33 million printed GIA Diamond Dossier reports were issued since the introduction of the service in 1998.

Pritesh Patel, GIA’s Chief Operating Officer, added, “In 2025, when all GIA reports are digital, retailers and consumers will find greater convenience and a more immersive experience. Eliminating printed reports is an important advancement, reducing the impact of using, shipping and storing the nearly 40 tons of paper and plastic that go into printed GIA reports each year.”

The secure digital GIA Diamond Dossier is available in the reimagined GIA App or on computers, tablets and phones through the robust and secure online GIA Report Check Service and the GIA advanced application programming interface (API) for commercial users. The digital report service includes a Report Access Card with the report number, a QR code linking to the digital report and 4Cs information to embed into receipts, invoices and e-commerce sites.

The new GIA App is widely available for Apple and Android devices. The Android app for China is in development and will be available at a later date. The GIA Match iDTM inscription matching service is expected to be available in the first half of 2023, accessible exclusively through the reimagined GIA App.

AGS Laboratories to Integrate with GIA

The American Gem Society (AGS) will close its laboratory operations at the end of this year, with the Gemological Institute of America (GIA) taking on elements of the organization.

AGS Laboratories’ intellectual property (IP), technology, research staff and Las Vegas facility will become part of the GIA, the two organizations announced Wednesday. AGS Laboratories will continue to provide services until the end of 2022 and will contact clients with details of the transition, it said.

The nonprofits, both founded by Robert M. and Beatrice Shipley in the 1930s, will combine their gemological research efforts. The amalgamated team will “develop innovative products” to help consumers and the trade, encompassing light-performance research and a “science-based” fancy-cut grade standard, they said.

“This consequential agreement brings AGS and GIA even closer, driving our future with 90 years of shared history and elevating our founders’ vision,” commented AGS CEO Katherine Bodoh in a joint statement.

The GIA will create an endowment to support AGS and its membership. They did not provide further financial details. The collaboration will also help advance AGS’s retailer programs and support more member education, for example at the annual AGS Conclave, the statement continued.

The AGS Ideal grading report will be available from GIA as a digital-only supplement to GIA reports for eligible D to Z natural and laboratory-grown round and fancy-shape diamonds, incurring an additional cost of $25. GIA clients will be able to request these extra reports from January 2023.

In an information sheet for customers, AGS noted that GIA was responsible for inventing the 4Cs of diamond grading while AGS “created light performance and ignited a discussion on sparkle.” For instance, the AGS is one of the few major labs to offer a cut grade for fancy-shape diamonds.

“By harnessing each other’s strengths to move forward boldly, consumers will be better protected, and we will ensure the longevity of the Shipleys’ vision,” said GIA president and CEO Susan Jacques.

Correction, October 20, 2022: An earlier headline incorrectly stated that the GIA was taking over AGS’s grading division. In fact, the AGS Laboratories grading operations will close, with the GIA taking over certain other elements of the organization, including research.

GIA Launches Diamond Origin Service

The Gemological Institute of America (GIA) has begun accepting submissions for a new service providing consumers with source verification for diamonds.

Leading manufacturers sent the first polished diamonds to the GIA’s Source Verification Service in early July, the institute said Wednesday. GIA-graded diamonds with confirmed origin information will be available to consumers when the initial submissions are returned and as more manufacturers join the program, the organization explained.

An independent auditing firm will vet all cutters before they enter the program. The auditors will confirm the company has the ability to track a diamond from receipt of the rough through the entire manufacturing process. The GIA will evaluate all participating firms regularly to ensure they are continuing to adhere to the guidelines, it noted.

Initially, the GIA will accept only polished natural diamonds with verified source documentation, including Kimberley Process (KP) certificates and invoices from vetted manufacturers. It will add lab-grown diamonds to the service in the near future. Consumers can access the information through the GIA’s online Report Check service, it added.

“GIA’s new service provides diamond-source information to consumers as quickly as possible,” said its CEO, Susan Jacques. “The GIA Source Verification Service is ready to provide verified diamond-source information to address increasing consumer demand and government interest in transparency and traceability across the supply chain.”

All GIA Reports to Be Digital by 2025

                          

The Gemological Institute of America (GIA) plans to convert all of its paper reports to digital within the next three years, beginning with its Diamond Dossier in 2023.

The digital reports, which it will link to an app, will be more secure than their paper counterparts, the GIA said Tuesday. They will be paired with a new inscription-matching service, called GIA Match iD. This feature captures a diamond’s inscription image and links the stone to its GIA report using artificial intelligence (AI).

As each report category is introduced in digital form, the printed reports will be discontinued, the GIA told Rapaport News. However, some specialty services, such as the Monograph reports and notable letters, will continue to be available in printed versions.

“Digital reports…build on our decades of innovation and move our consumer protection mission forward,” said GIA CEO Susan Jacques. “This important transformation allows GIA to offer consumers a truly modern and engaging experience while helping our industry progress toward a more sustainable future.”

Starting in January 2023, the new Diamond Dossier service will offer a fully digital report, including the 4Cs; the app, which enables retailers and consumers to view, save and share information for their diamonds; and the Match iD instrument.

The elimination of GIA paper reports will save 20 tons of paper and 18.5 tons of plastic each year, the GIA said. It will also reduce transportation-related carbon emissions, the institute added.

GIA Sees Spike in Synthetics Fraud

 

               GIA Sees Spike in Synthetics Fraud

The Gemological Institute of America (GIA) has seen a rise in submissions of lab-grown diamonds with counterfeit inscriptions that make the stones appear natural.

Clients using the GIA’s update or verification services are increasingly sending in goods that prove to be synthetic, the organization said Monday. These stones have falsified girdle engravings that reference a genuine natural-diamond report number, while most have almost identical measurements and weights to the natural diamonds they mimic.

In a recent case, someone submitted a 3.075-carat, H-color, VVS2-clarity, triple-Ex, lab-grown diamond to GIA Antwerp for an update. The stone carried a report for a 3.078-carat, G-color, internally flawless, triple-Ex natural diamond. The synthetic stone’s real-life dimensions were within hundredths of millimeters of the measurements in the natural-diamond report, the GIA noted.

“This unfortunate situation demonstrates why it is important, especially in any transaction where the buyer does not have a trusted relationship with the seller, to have the diamond-grading report updated before completing a purchase,” said Tom Moses, the GIA’s executive vice president and chief laboratory and research officer.

The GIA blotted out the counterfeit inscription and inscribed a report number for a new certificate that it issued, adding the term “laboratory-grown” on the girdle, as is its practice.

In February, the institute reported that it had received a number of lab-grown or treated stones carrying natural reports and fake inscriptions.

GIA Calls Off New York Career Fair

The Gemological Institute of America (GIA) has canceled next week’s career event in New York due to the coronavirus.

The GIA Jewelry Career Fair was due to take place on March 13. It targets job seekers in the greater New York City area, and is open to the public. The organization plans to find a new date for the event.

“We believe this is in the best interest of all participants’ health and safety,” a GIA spokesperson said Wednesday.

Last year, the fair attracted more than 450 students, GIA alumni, job seekers and other professionals, as well as 56 companies looking to hire and 23 career coaches.

The GIA has already reduced the operating hours at its Hong Kong and Tokyo laboratories due to the health situation. It continues to monitor the conditions in all its locations, the spokesperson added.

Concerns about the spread of the coronavirus in the US increased this week. As of Wednesday, nine people had died out of a total of 80 cases across 13 states, according to the Centers for Disease Control and Prevention. The US has not yet banned public events, but California declared a state of emergency on Wednesday.

The JCK Las Vegas and Luxury shows will still take place in late May and early June, organizers Reed Jewelry Group confirmed on Tuesday. This week’s Hong Kong shows and the Baselworld fair — scheduled for April 30 to May 5 in Switzerland — have both fallen victim to the epidemic.

GIA Suspends Diamond Sealing Services Following Tampering

GIA (Gemological Institute of America) has announced that it is suspending its diamond sealing services. The suspension is effective immediately and comes following the discovery that “a small number” of GIA sealing packets that had been compromised by third parties after the sealing packets left GIA. 

The Institute said that in these cases, the original diamonds had been replaced with HPHT (high-pressure, high-temperature) treated natural diamonds. 

The replacement diamonds superficially matched the GIA report information for the original diamonds, including information on the sealing packet data label.

GIA said that anyone who has concerns about a GIA-sealed diamond can submit the unopened packet to any GIA laboratory for verification services. If GIA concludes the diamond in the sealing packet is the diamond described in the original report, the Institute will issue a verification letter confirming the diamond matches the original report. If this is not the case, the Institute will issue a new report with the correct results. 

The Institute will provide this verification service free-of-charge for diamonds received in a sealed packet. All sealed diamonds submitted will be returned unsealed.

GIA Unveils Plans for Labs in Surat and Antwerp

The Gemological Institute of America (GIA) will this year open a laboratory in Surat, and expand its operations in Antwerp to include diamond grading.
The GIA has secured premises for the two locations, and expects to open both in the second quarter, it said Monday.
The Surat laboratory will bring the GIA’s services — including its Melee Analysis Service for detecting synthetics — closer to companies in that important manufacturing hub, the organization noted. In Antwerp, it will introduce diamond-grading services, and increase capacity for its mine-to-market (M2M) program, which matches rough diamonds to their resulting polished, the lab said.
“Expanding our facility in Antwerp, and opening a new location in Surat, continues GIA’s mission-driven effort to bring our research-based laboratory services for diamonds, colored stones and pearls ever closer to our clients,” said Tom Moses, the GIA’s executive vice president and chief laboratory and research officer.
Clients will be able to drop off goods for every service at both the Surat and Antwerp labs, the GIA added.

Synthetic Diamond Fraudulently Inscribed To Match Natural Diamond Report

Improvements in diamond growth technology and methods have led to a noticeable increase in colorless synthetic gem diamonds in recent years. Concerns in the diamond industry focus on laboratory-grown diamonds not being properly disclosed or even being sold as natural stones. Through careful examination and analysis, gemological laboratories can separate natural from synthetic diamonds. Occasionally, however, fraud is involved in attempting to conceal a gem’s identity. The Carlsbad laboratory witnessed such an attempt.
On this occasion, a round brilliant cut (figure 1, left) was submitted for an updated diamond grading report. Its girdle was inscribed with an actual GIA report number issued in 2015 (figure 1, right). The older report was for a natural, untreated diamond and contained the following grading information: 1.74 ct, round brilliant cut, D color, Excellent cut grade, and VVS₁ clarity. Upon grading, the new submission was described as a 1.76 ct round brilliant cut with F color, Excellent cut grade, and VS₁ clarity. Moreover, our screening processes determined that the newly submitted sample needed additional testing to determine its origin. This examination revealed it to be an HPHT-grown synthetic diamond. Synthetic cuboctahedral growth structure and phosphorescence were clearly visible in DiamondView imaging (figure 2).

Figure 2. DiamondView imaging showed the synthetic growth structure and blue phosphorescence typical of HPHT-grown synthetic diamonds.

Aside from the observed discrepancies in weight (1.74 vs. 1.76 ct), color (D vs. F), and clarity (VVS₁ vs. VS₁), FTIR spectra clearly showed that these were not the same diamond. The natural diamond from the original report was type Ia with aggregated nitrogen impurities, while the new one was type IIb with boron impurities (figure 3). Careful examination of the report number inscribed on the synthetic diamond revealed a font different from the one used by GIA, proving that it was not an authentic inscription.

Figure 3. FTIR absorption spectra revealed that the synthetic diamond was type IIb, whereas the fraudulently inscribed report number referred to a natural type Ia diamond. The spectra are offset for clarity.

While most synthetic diamonds that come to the laboratory are properly disclosed, some are submitted out of concern that a stone presented as natural might be synthetic. Rarely do we encounter the type of blatant fraud described here. It is important for the industry and public to exercise caution, because these types of misleading practices do occur. We believe the submitting client noticed inconsistencies with the GIA report information and sent it to the lab for an updated report. If any doubt exists or some aspect of a diamond (such as an inscription) seems odd, the stone should be sent to a gemological laboratory for verification.
