The Kimberley Process started when Southern African diamond-producing states met in Kimberley, South Africa, in May 2000 and has been in force since 2003. It is open to all countries and as of 2013, it has 54 participants, representing 81 countries all around the world from the European Union to United States.
It is a civil society initiative and implements the requirements of preventing the flow of conflict diamonds coming from conflict zones, defined as such by the United Nations. The Kimberley Process Certification Scheme (KPCS) guarantees that each rough diamond that crosses an international border between two signing countries are conflict-free.
Nivetta certifies that all of its diamonds are bought on the basis of written guarantees produced by its suppliers which are in compliance with the Kimberley Process.
