Conflict diamonds

Ensuring our supply chain is free from conflict diamonds (rough diamonds sold by rebel groups or their allies to fund conflict against legitimate governments) is critical to maintaining consumer confidence in our industry.

We work in close partnership with our industry peers, governments, customs authorities and civil society groups in support of the Kimberley Process. Founded in 2003, this international, multi-stakeholder initiative was created to increase transparency in the diamond industry to eliminate trade in conflict diamonds.

To participate in the Kimberley Process, member states must enact national legislation that meets minimum requirements and ensure relevant institutions, including those responsible for imports and exports, meet certain standards.

Rough diamonds must be transported in sealed, tamper-resistant containers accompanied by forgery-resistant certificates with unique serial numbers. This process is backed by a system of internal controls in the producing countries, and those countries that trade, cut and polish rough diamonds.

To support the implementation of the Kimberley Process, the diamond industry developed a ‘System of Warranties’. This requires companies to ensure that all invoices for rough or polished diamonds, and diamond jewellery, include a written guarantee that the diamonds are conflict-free. Records of all warranty invoices must be kept and are externally audited annually.

All De Beers’ diamonds are certified conflict-free and our audit processes confirmed 100 per cent compliance with the Kimberley Process for 2016.
