International Recognition
Dimexon is internationally known as a trusted supplier of cut and polished diamonds. We work closely with our clients, many of which are prestigious watch and jewellery brands, to ensure delivery of exceptional diamonds across a range of cuts and sizes. We have used our decades at the forefront of the industry to combine investment in technology with individual craftsmanship. Our particular area of expertise is round brilliants, which include a range of Forevermark and Hearts & Arrows diamonds. Dimexon is also able to offer a bespoke selection of rare and exceptional stones.
Our suppliers
Transparency is one of our fundamental values. We guarantee that our diamonds have the shortest journey from mine to jewellery, and can give solid assurances about the high ethics and quality throughout our supply chain. Dimexon sources its supplies from the largest diamond mining companies in the world, including De Beers and Rio Tinto. This allows us to offer ethical materials from certified origins. As only our larger diamonds are sold with GIA certificates, it is crucial for us to partner with mining companies that are in line with our core values. This way, we can ensure that the manufacture of our diamonds result in fair wages, the empowerment of women, local community benefaction, environmental protection, and societal wellbeing.
De Beers
De Beers operates in Botswana, Canada, Namibia and South Africa.
It works closely with local governments and communities supporting its business to ensure the sale of its diamonds benefits the people and places where they are discovered.
Rio Tinto
Rio Tinto owns and operates the Diavik mine in Canada. It supports responsible and ethical social and environmental practices throughout the supply chain by working alongside local communities and monitoring activities, sharing insights with stakeholders regularly.
