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. This transformative change marks a historic shift in the global diamond industry, not only redefining the value perception of lab-grown diamonds but also enhancing the differentiation between natural and lab-grown initiative is not merely a terminology adjustment; it represents a systematic effort to separate the grading systems for lab-grown and natural diamonds. 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. Every natural diamond is unique, characterized by its distinct growth patterns, inclusions, and colour formed over billions of years.

Their industrial nature limits their ability to embody the multiple values associated with natural diamonds, including emotional attributes, rarity, investment potential, and heritage. GIA's reform not only reaffirms the irreplaceable status of natural diamonds but also clarifies that lab-grown diamonds should not be assessed using the same criteria as natural time, some lab-grown diamond sellers have been using ambiguous marketing terms such as "sustainability" and "equivalency" that may mislead consumers about the differences between lab-grown and natural diamonds. GIA's new approach ensures consumers can make informed choices without confusion, protecting their rights to knowledge, choice, and fair trade. By discontinuing the use of the 4Cs standard for lab-grown diamonds, GIA reaffirms its commitment to scientific integrity and public grading redefinition is poised to have a profound impact on the global jewellery industry. As this change takes effect by the end of 2025, it is anticipated that gemological institutes worldwide will follow suit.

HONG KONG SAR - Media OutReach Newswire - 10 June 2025 - The Gemological Institute of America (GIA), the world's foremost authority in gemology announced a redefinition in diamond grading on June 2, 2025. Beginning at the end of 2025, GIA will cease using the internationally recognized 4Cs grading system (Cut, Colour, Clarity, Carat) for lab-grown diamonds. Instead, 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.

GCAL By Sarine Gemstone ID Lab Communicates Ethos Of Integrity At JCK
GCAL By Sarine's proprietary; radically rigorous 8X Ultimate Diamond Cut Grading standards assess ... More round, marquise, pear, princess, oval and radiant cut diamonds. According to Avi Levy, New York-based Chief Growth Officer at the gemstone identification laboratory GCAL by Sarine, 'While consumer trust in diamond and colored gemstone grading labs is essential for a healthy, high-functioning gemstone market and jewelry industry, many diverse factors contribute to this trust.' To begin with, Levy insisted, 'Of primary importance is using crystal clear terms to communicate grading standards and the criteria used to assess a diamond's characteristics.' Labs like GIA, IGI and GCAL by Sarine are consulted by consumers and those in the gem and jewelry trades due to their consistency, accuracy, and adherence to strict gemological standards. (GCAL by Sarine's parent company Sarine Technologies Ltd. is a publicly traded company that develops, produces and sells technologies for the diamond industry, including devices for the planning, analysis and grading of rough and polished diamonds.) This writer spoke to industry veteran Levy and GCAL by Sarine president Angelo Palmieri as they were launching the lab's new 8X Radiant Cut Grade at the JCK show in Las Vegas. As North America's largest gemstone and jewelry-related trade show, JCK is a foundational platform for labs like GCAL by Sarine to articulate advances in diamond grading standards. By extension, JCK serves as a venue for building trust in those standards among the jewelry manufacturers, retailers and designers who ultimately articulate those standards to consumers. Consumer trust in gemstone identification labs is so absolutely vital as those businesses provide objective, third-party assessments that help consumers, retailers and others understand, and verify, a diamond's quality. 'GCAL written assessments help clients make decisions informed by objective evidence,' Levy opined, 'rather than marketing statements or emotion.' But how does a company like GCAL by Sarine go about grading diamonds and other gemstones, plus communicate with customers so all parties learn and benefit from the interaction? As Levy explained, 'Just as all diamonds, colored gemstones and pearls are unique, each gem identification and grading laboratory is unique in that it follows proprietary protocols-- and embodies a singular ethos. GCAL,' he continued, 'is the only gem ID and grading lab in the world to offer a 4Cs Grading Guarantee. GCAL," he maintained, "provides an unparalleled assurance of diamond quality with every certificate it issues.' This grading guarantee, Levy continued, 'ensures accuracy, consistency, and transparency, delivering three vital values that consumers, retailers and manufacturers" all deserve-- yet may never obtain. 'We are here to help customers understand the factors that contribute to a diamond's value and beauty,' Levy detailed. 'We educate our clients and our website educates the public by detailing the whys and wherefores of diamond grading and the factors that affect a diamond's value.' Equally important, in the very rare cases in which GCAL issues a report that is later proven to be inaccurate, if a diamond's grading is found to be lower than what's stated on the GCAL certificate, the company will reimburse the customer the difference between what they paid and the fair market value of an equivalent diamond. 'We will pay the difference and make the customer whole,' Palmieri said. 'We are too committed to our customers, and to the truth, to do anything else.' FEATURED | Frase ByForbes™ Unscramble The Anagram To Reveal The Phrase Pinpoint By Linkedin Guess The Category Queens By Linkedin Crown Each Region Crossclimb By Linkedin Unlock A Trivia Ladder Moreover, Levy noted, GCAL is constantly striving to develop deeply discerning cut grades in order to provide more rigorous protections for clients, whether they be newlywed consumers, retailers, jewelry manufacturers or global jewelry brands. For example, Levy explained, 'GCAL developed a radically rigorous cut grade to differentiate the best, brightest and most beautiful diamonds from all others, called the 8X Cut Grade. Unlike many other gem identification labs, we thoroughly assess the diamond in terms of light performance." This is important, Palmieri said, 'because certain cuts, such as Fancy Shaped oval, marquise and pear can be more prone to ugly shape outline issues or what we call the bow-tie effect, which is a darker area caused by light leakage." A bow-tie can make the diamond appear dull or shadowy, which in turn can lower the value of the stone." In 2025's diamond market, Levy emphasized, 'more than half of all the round brilliant cut diamonds are given Excellent cut grades, but less than one per cent qualify as 8X. The GCAL 8X Ultimate Cut Grade, he continued, 'gives quality-conscious, discerning consumers a way to confidently select the most brilliant and beautiful diamonds, even when purchasing them online, sight unseen.' As Palmieri observed, 'If you care about cut, you will care about 8X and its radically thorough standards for assessing different diamond cuts.' Another way that GCAL by Sarine is building trust with clients involves 'documentation of diamond origin and AI diamond grading,' Levy said. For example, 'Artificial Intelligence (AI) makes verifiable diamond traceability possible. GCAL by Sarine technology captures extensive data about each and every diamond at a given mine, tagging each stone with a unique, unalterable registration number and then tracks it on its journey through the manufacturing process, while adding information along the way. This information is stored securely in the Sarine cloud,' Levy stated, 'and several safeguards are in place to prevent tampering or falsification.' As Palmieri put it, 'We're a heritage company that started like a premium small-batch label and yet we grew globally without ever compromising. People trust us because we do things right, with precision, integrity, and heart.' What's more, he added, 'We've been using AI-based color and clarity grading technologies since 2018, well before many of our competitors even knew what AI was, so we remain ahead of the curve.' Levy added that GCAL collaborates with various organizations to address ethical concerns related to diamond sourcing and the environment. 'In this industry,' he noted, 'you are only as strong as your alliances, and we nurture our alliances with fellow stakeholders for the good of our business and the consumers who support us.'
