Impact Through Provenance 

Our 2023 ESG Report and Roadmap to Sustainable Luxury

The past year has made it clear that provenance is more important than ever in the diamond industry. That’s why the theme of our 2023 ESG report is Impact Through Provenance. 

As you will read in our latest report (which refers to our ESG activities in 2022), our ESG strategy guided and tracked our efforts around provenance, product integrity and responsible sourcing. We decided to further enhance the transparency of our supply chain, sharing more traceability and provenance information with customers and stakeholders. To do so, our systems and assurance processes were upgraded to provide our customers with auditable confidence in our diamonds. 

This year’s theme of Impact Through Provenance is aligned with our overarching purpose of Inspiring Sustainable Luxury. As such, this year’s report includes some ambitious targets to help us play our part in fighting climate change. 

Through innovation and collaboration, Dimexon continuously strives to improve operations, promote sustainability and drive positive change in the wider industry. Join us on our journey by downloading our 2023 ESG report.
