Roberto Coin purchases polished diamonds only from legitimate sources who subscribe to an international system of certification and warranties known as the Kimberley Process Certification Scheme (KPCS) and The System of Warranties. Roberto Coin has a zero-tolerance policy towards conflict diamonds.

The KPCS is a joint government diamond industry and NGO initiative that imposes extensive requirements on its member countries to enable them to certify the origin of their rough diamonds and prevent illicit or “conflict” diamonds from entering legitimate trade.

The System of Warranties is an extension of the Kimberley Process, where members of the diamond trade provide a written guarantee on all invoices that the diamonds are conflict free. All warranties whether given or received must be audited and reconciled on an annual basis. The System of Warranties provides assurance that diamonds are from conflict free sources all the way to the diamond jewelry retailer.
