The Kimberley Process Certification Scheme was created by the United Nations in 2002. The scheme originated from a meeting of South African diamond producing states in 2000 in the town of Kimberley, the capital of the Northern Cape in South Africa. This extraordinary event is depicted at the end of the film 'Blood Diamond'.
The scheme is designed to prevent conflict diamonds from entering legitimate jewellery supply chains, so we can know that the diamonds we're using aren't blood diamonds. Around 47 countries now adhere to the Kimberley Process, including all member countries of the European Union.
Under the Kimberley Process, any country which is part of the scheme has to ensure that any diamond mining is strictly supervised and that diamonds in their rough and uncut and un-polished state can only be transferred between participating countries in tamper-proof containers and with proper documentation.
Every diamond export is accompanied by a Kimberley Process certificate proving that any diamond originating from that country does not finance a rebel group or other faction seeking to overthrow a UN-recognized government. The country must also ensure that no diamonds are imported to or exported from a country or state that is not a member of the Kimberly Process scheme. This means in practice that every packet of diamonds is tracked from the mine to the point of cutting. Once the stones have been cut and polished the World Diamond Council System of Warranties ensures that the diamond supply chain continues to be protected.
There have been some reports that the Kimberley Process is not foolproof. The problem with the process is that a country only has to meet the minimum requirements to become a member and that the scheme is self-enforced by the individual member countries. Whilst it is still being monitored and reviewed by official observers such as the World Diamond Council and Global Witness, there is still room for tampering.
An example of this is in 2004 when the Republic of Congo (not to be confused with the Democratic Republic of Congo) was expelled from the list of participants in the scheme due to its constant failure to comply to the minimum requirements needed to participate. Whilst the Republic of Congo has no mining itself, it acts as a conduit for illicit diamonds smuggled from neighbouring Kimberley Process participants such as the Democratic Republic of Congo and Angola.
In 2005 investigations by Global Witness showed that Lebanon, who were at the time applying to be listed as a participant of the scheme, had imported diamonds from the Republic of Congo breaking one of the main requirements of the process. It is near impossible to make sure a scheme such as the Kimberley Process is entirely adhered to all the time by every country involved. Whilst the process now covers 99.8% of the world's diamond trade we are also active in working with our suppliers to make sure that none of that 0.2% make their way here.
We use suppliers we've built up a relationship with over a number of years, and we know that they only use suppliers they trust, creating a web of trust as a valuable safeguard to make sure the diamonds we use are sourced responsibly. Short of buying our own diamond mine we have done our utmost to ensure this.
