Responsible Sourcing & Kimberley Process
Kimberley Certification: What It Covers—and What It Does Not
Kimberley certification refers to the Kimberley Process Certification Scheme, an international system designed to prevent shipments of conflict rough diamonds from entering legitimate trade. Participating shipments of rough diamonds cross borders in tamper-resistant containers accompanied by government-validated certificates. The scheme is important, but its scope is limited. It regulates rough-diamond trade between participating jurisdictions; it is not a grading report, not a certificate for an individual polished diamond and not a complete ethical guarantee covering labour, environment, human rights or every stage of the polished supply chain. A private buyer should treat Kimberley compliance as one layer of due diligence and request additional seller, invoice, warranty and provenance information where responsible sourcing matters.
What the Certification Scheme Is
The Kimberley Process Certification Scheme began in 2003 through cooperation among governments, industry and civil society participants.
Its central purpose is to reduce trade in rough diamonds used by rebel movements to finance conflict against legitimate governments.
Participating jurisdictions establish controls for the import and export of rough diamonds.
What a Kimberley Certificate Covers
The certificate accompanies a shipment of rough diamonds, not a single polished stone sold at retail.
It confirms that the shipment is handled within the participant system and meets the scheme’s defined requirements.
The certificate is government validated and tied to a specific shipment.
What It Does Not Cover
It does not grade colour, clarity, carat weight or treatment.
It does not independently certify every labour, environmental or human-rights issue.
It does not provide a permanent ethical passport that follows every polished diamond through every later transaction.
Due Diligence Beyond Kimberley Compliance
Buyers may also review supplier policies, invoices, source representations, chain-of-custody records and the World Diamond Council System of Warranties.
OECD due-diligence guidance provides a broader risk-based framework for mineral supply chains.
No single document should be treated as a complete ethical guarantee.
Common Misunderstandings
A GIA, HRD or GCAL report is a gemmological document and is not a Kimberley certificate.
A retailer’s statement that a polished diamond is Kimberley certified usually refers indirectly to upstream rough-diamond compliance, not to an individual retail certificate.
Kimberley compliance does not guarantee future value or lawful title in the present transaction.
What This Means for a Private Buyer
Ask what evidence supports the seller’s responsible-sourcing representation and what period of the chain it covers.
Use the Responsible Sourcing & Kimberley Process hub, the broader Kimberley Process guide and the explanation of Kimberley Diamonds: The Name, the Region, the Process. Pelican can incorporate supplier and documentation review within private sourcing.

No. It addresses a defined conflict-diamond scope and is not a complete ethical guarantee.
