SIGHTHOLDER OF THE
DE BEERS GROUP
Dianco has been a De Beers Group Sightholder since 2012. Only a handful of companies that comply with their requirements are privileged enough to be selected to be part of the De Beers Group Sightholder family. They control the second largest distribution of mined, rough diamonds around the world. 90% of their rough diamonds that come from their mined operations in Canada, South Africa, Namibia and Botswana are sold to their Sightholders.
As a Sightholder, we receive a consistent and regular supply of their diamonds. About 10 times a year our team heads over to Botswana to inspect the goods before deciding what to buy. We are proud to say that all of the De Beers mines are certified by the Responsible Jewellery Council Code of Practices and are compliant with the De Beers Group Best Practice Principles. Giving our team and our customers assurance on the integrity and authenticity of the diamonds.
