This standard is the first comprehensive, multi-stakeholder sustainability standard developed for the diamond sector and applies to both natural and laboratory-grown diamonds, including any entity that handles the diamonds on their way to market. This standard establishes unprecedented benchmarks of performance and transparency, featuring: 1) stringent environmental, social and governance (ESG) achievement; 2) net zero carbon footprint; 3) sustainable production practices with net zero impact; 4) comprehensive origin traceability for the highest possible source-to-market certainty; and 5) sustainability investments that support vulnerable communities, reduce net impacts further, and contribute to a safer world.
