Editor’s Note
The Responsible Jewellery Council has introduced new standards specifically for lab-created diamonds, aiming to bring greater transparency and consistency to this expanding segment of the jewellery market. This move underscores the industry’s effort to apply rigorous ethical and environmental practices across all diamond sources.

The Responsible Jewellery Council (RJC) has released a new set of rules specifically governing lab-created diamonds. This move aims to provide clear standards and transparency for the growing sector of synthetic diamonds within the jewellery industry.
The new framework addresses key areas including disclosure, marketing terminology, and supply chain due diligence for lab-created diamonds. It mandates that members must clearly distinguish lab-created diamonds from natural diamonds in all communications to consumers. The rules are part of the RJC’s ongoing efforts to adapt its certification standards to evolving market realities and consumer expectations.
