The “CIBJO Guidelines for Measuring ESG Performance,” created by CIBJO’s Laboratory-Grown Diamond Committee in collaboration with Key & Co. and the Sustainable Development Commission, provides a comprehensive framework suitable for various sectors of the jewellery industry, ranging from large corporations to smaller businesses. Unlike the earlier document, which focused solely on lab-grown diamonds, these updated guidelines apply across the entire jewellery supply chain.

The guidelines are organized around 14 key ESG themes, each with detailed measurement areas and example metrics. Acknowledging the diverse and fragmented nature of the jewellery industry—especially the challenges faced by artisanal mining and small and medium-sized enterprises (SMEs)—the document presents a practical 10-step approach for companies beginning their ESG journey. It also includes a glossary of terms to clarify complex language.

CIBJO President Gaetano Cavalieri emphasized the importance of the guidelines, stating, “This is a highly valuable resource, and we are pleased to make it freely available to all industry members.” He also pointed out the increasing trend of turning ESG principles into legal obligations, referencing the European Commission’s upcoming ESG regulations as an example.

Set to take effect in 2027, these new regulations will require many listed SMEs to disclose their ESG impacts. Cavalieri highlighted the need for the industry to prepare in advance, positioning the guidelines as an essential tool in this preparation process.
