Diamonds Manuka Sustainability Actions

Uses ESG and due diligence systems

The available material says the business works with ESG (environmental, social, and governance) standards and due diligence systems to manage risk in the diamond trade. It mentions using frameworks such as GRI Standards, the Corporate Sustainability Reporting Directive, the UN Sustainable Development Goals, and the OECD 5-step due diligence framework. In plain terms, this means the company is trying to track environmental and social risks, document them, and show how it handles them across the supply chain.

Focuses on traceability

The content describes end-to-end traceability, meaning each stone is documented from rough intake to polished output so it can be checked later. It also mentions chain-of-custody and auditing protocols. This kind of system is used to help prove where diamonds came from and how they moved through the supply chain. That matters because diamond sourcing can involve human rights, conflict, and fraud risks.

Uses third-party certification

One source says the company has been a certified member of the Responsible Jewellery Council since 2012 and completed a fourth recertification in 2025. RJC certification is a third-party check on responsible business practices in the jewellery sector. The same material also says the company follows the Kimberley Process Certification System and the World Diamond Council System of Warranties, both of which are meant to reduce conflict-diamond risk and improve sourcing controls.

Supports education in East Africa

The company says it supports Action in Focus, an organisation that helps children in rural East Africa access education, healthcare, and basic services. It says it has helped more than 150 children through primary school over the past decade and continues to sponsor pupils through secondary education. This is a social-impact action rather than an environmental one, and it links to community support and access to education.

Sets labour and human rights rules

The content says the company applies human rights and fair labour policies across its own manufacturing site and wider operations. It also says it has policies on child labour, anti-discrimination, anti-harassment, anti-bribery, and business ethics. These policies are meant to reduce harm to workers and make the supply chain easier to audit. The material also notes a grievance mechanism, which is a formal way for people to raise concerns.
