Diamond Education
The term “conflict-free diamond” is used for diamonds that are not connected with the financing of conflict under the applicable sourcing framework. However, the meaning of the term depends on the definition, documentation and due-diligence system being used.
The Kimberley Process was created to prevent conflict diamonds from entering the legitimate international rough-diamond trade. Additional industry warranties, supplier checks and responsible-sourcing programs may extend review further through the polished-diamond and jewellery supply chain.
This guide explains what conflict-free means, how the Kimberley Process works, what it does not automatically guarantee and what questions to ask before purchasing a diamond.
Understanding the Term
A conflict-free diamond is generally described as a diamond that has not financed armed conflict under the sourcing standard or assurance system being applied.
Under the Kimberley Process definition, conflict diamonds are rough diamonds used by rebel movements or their allies to finance armed conflict aimed at undermining legitimate governments.
A diamond sold as conflict-free should come through legitimate channels supported by appropriate sourcing controls, commercial records and supplier assurances.
Because different programs can cover different risks, shoppers should ask what the seller means by “conflict-free” and what evidence supports the claim.
Different Levels of Assurance
These terms are related, but they should not automatically be treated as identical.
Conflict-Free
The term commonly focuses on whether diamonds are connected with financing armed conflict under a stated definition or certification framework.
Responsibly Sourced
Responsible sourcing may examine additional business, social, environmental and governance risks throughout the supply chain.
Terminology
“Blood diamond” is an informal term commonly associated with diamonds linked to violent conflict, rebel financing and serious harm.
The formal Kimberley Process definition uses the term “conflict diamonds” and applies specifically to rough diamonds used by rebel movements or their allies to finance armed conflict aimed at undermining legitimate governments.
Public discussions may use “blood diamond” more broadly than the formal Kimberley Process definition. This is one reason shoppers should examine the exact language and scope of a sourcing claim.
International Rough-Diamond Trade
The Kimberley Process is an international certification scheme designed to prevent conflict diamonds from entering the legitimate rough-diamond trade.
Participating countries must establish controls and meet minimum requirements for handling international rough-diamond trade.
Rough-diamond trade is permitted between Kimberley Process participants operating under the scheme.
Rough diamonds intended for international trade must be handled in tamper-resistant or appropriately controlled containers.
Each qualifying international shipment of rough diamonds must be accompanied by a valid Kimberley Process certificate.
Authorities review shipments and apply customs, record-keeping and reporting requirements.
Participants exchange information and work through monitoring, review and enforcement procedures.
Understanding the Scope
The scheme is an important control for international trade in rough diamonds, but it should not be interpreted as a complete assessment of every supply-chain issue.
| Area | What the KP Addresses | What Requires Additional Review |
|---|---|---|
| Product Stage | International trade in rough diamonds. | Polished diamonds and finished jewellery require downstream commercial controls and supplier assurances. |
| Conflict Definition | Rough diamonds used by rebel movements or allies to finance armed conflict against legitimate governments. | Other violence, abuse or state-related risks may require broader due diligence. |
| International Shipments | Participant-to-participant rough-diamond trade supported by valid certificates. | Internal controls and movement after import depend on national, industry and company systems. |
| Labour Conditions | Not the primary purpose of the rough-diamond certification scheme. | Working conditions, wages, health, safety, forced labour and child labour require wider supplier due diligence. |
| Environmental Impact | Not a complete environmental certification for a mine or diamond. | Land, water, energy, waste, rehabilitation and biodiversity require mine-specific evidence. |
| Community Impact | Not a complete community-development or human-rights standard. | Consultation, displacement, local benefits and community safety require broader assessment. |
| Corruption Risks | Trade controls can support legitimate channels. | Bribery, corruption, money laundering and beneficial ownership require additional compliance systems. |
| Retail Guarantee | The original valid certificate applies to a rough-diamond shipment. | Retail claims should be supported through supplier warranties, invoices, traceability and company policies. |
Shipment Documentation
A Kimberley Process certificate is used for qualifying international shipments of rough diamonds—not normally as an individual retail certificate attached to every polished diamond.
One rough-diamond shipment can contain many stones. Those stones may later be sorted, sold, cut, polished and distributed through multiple companies.
Downstream businesses therefore rely on commercial records, supplier warranties, invoice statements, sourcing policies and other traceability systems to carry assurances through the polished-diamond and jewellery supply chain.
Downstream Commercial Assurance
The World Diamond Council System of Warranties was developed to complement the Kimberley Process and help pass sourcing assurances through the commercial diamond supply chain.
Under the system, participating buyers and sellers use warranty statements on business-to-business invoices or memos when rough diamonds, polished diamonds or diamond jewellery change hands.
The revised framework also encourages responsible business practices, supplier checks, record keeping and due diligence.
A warranty statement is part of a company-controlled business system. Its reliability depends on supplier assessment, records, implementation and the quality of the underlying due diligence.
Beyond Minimum Compliance
Due diligence is an ongoing process used to identify, assess, prevent, mitigate and communicate supply-chain risks.
Create sourcing policies, assign responsibility, maintain records and communicate requirements to suppliers.
Review supplier locations, ownership, business practices, conflict risks and available documentation.
Prevent, mitigate, monitor or disengage from risks depending on their nature and severity.
Relevant supply-chain controls may be assessed through audits, certification or other independent verification.
Companies should communicate policies, processes, significant risks and actions taken.
Country, supplier and conflict risks can change, so due diligence should be updated rather than treated as a one-time check.
Broader Risk Assessment
Whether diamond revenue supports armed groups, violence or prohibited actors.
Risks involving abuse, coercion, forced labour, child labour or serious discrimination.
Health, safety, training, protective equipment and emergency procedures.
Land rights, consultation, displacement, local security and the distribution of benefits.
Land, water, energy, emissions, waste, biodiversity and mine closure.
Bribery, corruption, money laundering, tax practices and ownership transparency.
From Mine to Jewellery
A natural diamond may pass through several businesses before becoming finished jewellery.
Natural rough diamonds are recovered and initially recorded.
Rough diamonds are classified by size, shape and quality.
Diamonds may be exported and sold under applicable trade controls.
Manufacturers plan, divide, shape and polish the rough material.
Polished diamonds may be graded and supplied to jewellers.
The diamond is set into a finished ring or other jewellery.
Product Transparency
Traceability is the ability to follow a diamond or defined parcel through identified stages of the supply chain.
Documents connecting rough material with a mine, country, supplier or verified source.
Controls that record possession, transfer and handling through the supply chain.
Procedures that prevent verified material from being mixed with material from unknown sources.
Technology or controlled records connecting a polished diamond with its original rough crystal.
Report numbers, digital records, laser inscriptions or other identifiers linked to the diamond.
Review by an auditor, laboratory, certification body or recognised assurance provider.
Geographic Origin
A standard diamond grading report usually focuses on whether the stone is natural or laboratory-grown and describes quality characteristics such as cut, colour, clarity and carat weight.
It does not automatically prove the mine or country from which a natural diamond originated.
Strong country-of-origin programs generally require records beginning before or during the rough-diamond stage. Controlled procedures can then connect the polished stone with documented rough material.
Evidence and Documentation
The available evidence depends on the seller, supplier, diamond and sourcing program.
Not every document provides the same assurance. Buyers should understand what was reviewed, who performed the review, which risks were covered and whether the document applies to the individual diamond.
Comparing Origins
Lab-grown diamonds are not recovered through diamond mining, so their production does not involve financing conflict through the mining of that individual stone.
Lab-Grown Diamond
A lab-grown diamond is created in a controlled facility using HPHT or CVD technology.
Natural Diamond
A natural diamond forms in the Earth and is recovered from a natural deposit.

There is no accessible sourcing policy or supplier standard.
A grading report is presented as proof of every ethical claim.
The seller guarantees zero impact without explaining the evidence.
General company claims cannot be connected with the specific item.
Policies or audit documents have not been reviewed recently.
Facts and Misconceptions
Myth
Conflict-free commonly addresses conflict financing. Other social and environmental impacts require additional assessment.
Myth
KP certificates apply to qualifying rough-diamond shipments. Downstream assurances rely on other records and warranties.
Myth
Standard grading reports primarily describe diamond identity and quality, not the entire supply chain.
Myth
Reliable geographic origin generally requires records maintained from the rough-diamond stage.
Myth
Labour, environmental, community and governance performance varies between operations and jurisdictions.
Myth
Lab-grown diamonds avoid mining the individual stone, but energy, materials, metals and manufacturing still have supply chains.
