The Government Diamond Office

How to export diamonds legally from the UK.


The Government Diamond Office is responsible for the implementation of the KP regulations in the UK and issuing authority for Kimberley Process Certificates. We work closely with HM Revenue & Customs, the UK diamond industry, the EC and civil society groups to implement the Kimberley Process Certification Scheme (KPCS) to combat the trade in illicit ‘conflict diamonds’.

The KPCS is a set of standards that regulates the trade in rough diamonds. It sets out the way in which each participating country handles the imports and exports of rough diamonds, as well as its internal controls for ensuring that domestic trading and processing are not contaminated by illicit sales.

Kimberley Certificates

Every rough diamond entering the UK or being exported outside of the EU must be accompanied by a Kimberly Certificate. There are no exceptions and the certificate must be acquired in advance. We recommend that exporters do not arrange transfer of diamonds until a certificate has been obtained.

Rough diamonds can only be imported from and exported to KPCS participating countries. A list of participating countries can be found at Kimberley Process.

Charge for Kimberley Certificates

We charge a fee for producing and issuing Kimberley Certificates. The cost of a certificate is £37.
