Key takeaways
- It certifies rough diamonds only. Polished stones fall outside it entirely.
- It works through the national law of each participant rather than as an international organisation with staff.
- A certificate travels with a sealed shipment under specific customs codes.
- It addresses conflict financing. It is not a general guarantee of legality, ethics or provenance.

The Kimberley Process is often cited as though it settles the question of whether a diamond is clean. It answers one question, about one form of the stone, and is silent on several others.
What it is
The Kimberley Process is a certification scheme covering international trade in rough diamonds. Its purpose is to keep conflict diamonds out of legitimate trade while allowing lawful trade to continue.
It is worth being precise about its legal character, because the common assumption that a global body polices diamond trading is wrong in a way that affects how you verify anything.
Verified fact[1]
The Kimberley Process is an international certification scheme regulating trade in rough diamonds.
Verified fact[1]
It has 60 participants representing 86 countries, with the European Union counting as a single participant.
Verified fact[1]
It is not, strictly speaking, an international organisation, and has no permanent offices or staff. It operates through the national legislation of its participants.
What a certificate actually attaches to
Certification is tied to a physical shipment and to specific customs classifications, not to a company or a relationship. That is a useful discipline: the question is always about this consignment.
Verified fact[1]
A certificate is required when exporting rough diamonds from a participant country under customs tariff codes 7102.10, 7102.21 or 7102.31.
Verified fact[1]
The scheme covers rough diamonds only. Polished diamonds do not require a Kimberley Process certificate.
Where it stops
This is the part that matters commercially. A valid certificate tells you a shipment moved through the scheme. It does not tell you that the seller has the right to sell, that the stones were lawfully won, that tax was paid, or that the working conditions behind them would survive inspection.
Treating the certificate as the end of diligence rather than one input into it is the mistake we see most often.
Capital Africa analysis
A Kimberley certificate should be read as a customs and conflict-financing control, not as a provenance guarantee. Everything an ordinary commercial buyer wants to know about title, licensing and counterparty identity sits outside its scope and has to be checked separately.
Requires further review
The treatment of synthetic and laboratory-grown stones is not addressed in the source consulted for this piece. Confirm the position with the relevant importing authority before relying on it.
