Transparency is one of our fundamental values. We guarantee that our diamonds have the shortest journey from mine to jewellery, reassuring high ethics and quality throughout the supply chain. Dimexon is sourcing its supplies from the largest diamond mining companies in the world: De Beers and Rio Tinto. This allows us to offer every jeweller, designer and
workshop ethical materials from certified origins. As only larger diamonds are sold with GIA certifications, it is crucial for us to partner with mining companies that are in line with our core values. Therefore, we can ensure fair wages, women empowerment, local community beneficiation, environmental protection, and societal well-being.
De Beers operates in Botswana, Canada, Namibia and South Africa. They work closely with local governments and communities supporting their industries and helping deliver the benefits of the diamonds to the people and places where they are discovered.
Rio Tinto own and operate the Diavik mine in Canada. They support responsible and ethical social and environmental practices throughout the supply chain by working alongside the local communities and monitoring activities and share the performance with stakeholders on a regular basis.
