Supply-demand and pricing dynamics have pushed the trade into a sharper dispute over how synthetic diamonds should be described, graded and distinguished from natural ones.<\/em><\/p>\n

\u201cIt\u2019s synthetics,\u201d an audience member shouted during a panel at the CIBJO Congress in Paris. \u201cExcuse me, I\u2019ve been badly trained,\u201d acknowledged David Kellie, the outgoing CEO of the Natural Diamond Council, who subsequently was careful not to use the term lab grown. Terminology has emerged as an important battleground, and it is likely to remain one as the trade pushes for language that clearly separates the product from natural diamonds.<\/p>\n

The Union Fran\u00e7aise de la Bijouterie, Joaillerie, Orf\u00e8vrerie, des Pierres et des Perles (UFBJOP), which hosted the congress, has been at the forefront of the push for more accurate wording.<\/p>\n

\u201cLaboratory grown is misleading because the diamonds are manufactured in a factory,\u201d said UFBJOP executive president Bernadette Pinet-Cuoq. \u201cIt is essential to question the acceptability of the word laboratory, and to reestablish a clear boundary between natural diamonds and synthetic ones.\u201d<\/p>\n

Earlier this year, the French government upheld its decision to use the term synthetic when describing factory-created diamonds. Officials cited a 2022 public consultation showing that most industry and consumer respondents supported keeping the term for clarity and consistency. The move counters criticism from a local politician who argued that synthetic is misleading and carries an unfair stigma in the context of luxury jewellery.<\/p>\n

For its part, the Gem & Jewellery Export Promotion Council (GJEPC) has recommended adopting the mandated definition, nomenclature and guidelines for diamonds specified by the US Federal Trade Commission (FTC). These require any businesses selling synthetics to qualify the word diamond with terms such as \u201ccultured,\u201d \u201claboratory-created\u201d or \u201claboratory-grown.\u201d<\/p>\n

In a Special Report for Diamonds published ahead of the congress, <\/em>members of CIBJO\u2019s executive revisit the organization\u2019s 2010 decision to accept terms like \u201clab-grown\u201d as synonyms for \u201csynthetic.\u201d The authors argue this blurred boundaries and lent synthetics undue legitimacy\u2014particularly through use of the 4Cs in grading. They also called for revisions to CIBJO\u2019s Diamond Blue Book to establish clearer terminology, restrict the 4Cs to natural diamonds, and strengthen consumer transparency.<\/p>\n

Labs Weigh In<\/strong><\/p>\n

The debate over terminology reflects the broader split within the trade about how to handle the synthetic\u2013natural divide and where the market is heading. That split was most visible in the contrasting approaches taken by the major grading laboratories.<\/p>\n

The Gemological Institute of America (GIA) ended its use of traditional colour and clarity grading for synthetic diamonds, replacing it with \u201cpremium\u201d and \u201cstandard\u201d quality descriptions. The shift reflects the narrow quality range of most lab grown goods and aims to create a clearer distinction from natural stones, the institute said in May.<\/p>\n

HRD Antwerp, a subsidiary of the Antwerp World Diamond Centre, went further by announcing it will stop certifying synthetic diamonds from 2026. The organisation said the move is intended to help consumers more easily tell natural and synthetic stones apart.<\/p>\n

The International Gemological Institute (IGI) took the opposite view, reaffirming its use of the full 4Cs for synthetics. It argued that consumer demand for lab grown diamonds calls for maximum transparency rather than reduced detail.<\/p>\n

Clear Differentiation<\/strong><\/p>\n

Meanwhile, the value of lab-grown diamonds continue to fall amid rising supply. India\u2019s exports of polished synthetic diamonds slipped 6% to $916 million in the first nine months of the year, according to data published by the GJEPC.<\/p>\n

Wholesale prices dropped 37% year on year in the third quarter, according to Edahn Golan\u2019s LGD Wholesale Price List, indicating that India, the largest producer of CVD goods, supplied higher volumes at lower prices during the period.<\/p>\n

Retail prices fell 14% year on year in the third quarter, which, while at a slower pace than the wholesale decline, indicates that retailer margins remain relatively strong for now.<\/p>\n

That cushion may come under pressure as many expect retail prices to adjust more sharply as discrepancies across different sales channels become clearer to consumers.<\/p>\n

The more prices diverge, the more critical it becomes for shoppers to understand exactly what type of product they are purchasing.<\/p>\n

These pricing inconsistencies only heighten the need for clear, honest terminology. As the gap between natural and synthetic diamonds widens on value, origin and market behaviour, the trade cannot afford language that clouds the distinction for consumers.<\/p>\n

Clear definitions have become one of the few tools the industry can rely on to reduce confusion as the market fragments. Pinet-Cuoq urged the broader industry to follow the French example.<\/p>\n

\u201cThe French decree [from 2002] defines a diamond as synthetic when it is man-made, and therefore a diamond that is not man-made is natural,\u201d she said. \u201cThat is our linguistic standard, which the authorities have confirmed. It is clear and avoids any confusion.\u201d<\/p>\n

Others will challenge the French position, but it is gaining traction among natural diamond advocates, ensuring that the debate over what to call a diamond will carry into the year ahead.<\/p>\n
