Kimberley Process conflict diamond reform: ESG and due-diligence lens for projects

30 Second Briefing
Efforts to reform the Kimberley Process have stalled again after the World Diamond Council spent three years drafting a broader “conflict diamond” definition to include non-state armed groups and explicitly recognise artisanal and small-scale miners. The proposed wording aimed to move beyond the current focus on rebel movements against legitimate governments, addressing violence linked to private security forces, criminal gangs and abusive supply-chain intermediaries. Continued deadlock leaves producers, cutters and retailers operating under a narrow legal definition that diverges from NGO expectations and many downstream buyers’ ESG due-diligence standards.
Technical Brief
- Industry participants now face dual compliance tracks: KP minimums plus stricter private ESG and responsible-sourcing schemes.
- Misalignment between KP and downstream buyer standards increases audit complexity and due-diligence transaction costs across supply chains.
- Similar definitional gaps in other critical-mineral schemes risk parallel fragmentation of assurance frameworks and reporting baselines.
Our Take
Within our Policy coverage, diamonds feature far less frequently than bulk commodities or battery metals, so renewed deadlock around conflict certification leaves a relatively small number of formal ESG tools doing most of the work for the sector.
For operators aligned with the World Diamond Council, stalled Kimberley Process reform increases reliance on parallel voluntary standards and chain-of-custody schemes, which can create uneven compliance baselines between large integrated producers and smaller alluvial or artisanal supply chains.
Among the 119 tag-matched pieces on Standards/Guidelines and Sustainability, most regulatory movement has been around climate and tailings; the lack of comparable progress on diamond-specific conflict definitions suggests reputational risk will continue to be managed more through corporate policy than binding multilateral rules in the near term.
