The French government recently reaffirmed the requirement to label lab-created stones as “synthetic diamonds.”
In early 2025, a proposal sought to change this and allow the use of “laboratory-grown diamond” or “lab-created diamond.” But after consultation with industry stakeholders, the Ministry of Economy judged that no significant legal, economic or technological developments warranted modifying the regulation.
According to the authorities, the goal remains ensuring clear, transparent and unambiguous information for consumers.
Under French law, the “synthetic” label applies to all man-made gemstones and pearls — and this classification applies equally to diamonds.
By upholding these rules, France underscores the importance of distinguishing natural diamonds from synthetic stones, aiming to protect consumer clarity regarding the true origin of the gemstone.
