Governance
The Taché Group as a whole, as well as each of its entities individually, continuously strive to uphold the highest industry standards. Amongst them, Taché France SAS, Taché Company NV and Taché Diamonds Botswana are all RJC certified members.
The Group, which includes the above stated entities, have conducted due diligence exercises on their supply chains, including on human rights and potential adverse impacts, and have not identified any red flags. The OECD five-step framework for risk-based due diligence on supply chains was followed.
The core of RJC Code of Practices is integrated through internal reviews of policies, procedures and practices – all of which are verified annually through client audits and internal reviews, as well as independent third-party audits every three years.
In upholding the highest industry standards, transparency towards our stakeholders is a key element. Each of the Group’s entities annually undertake a financial audit by an independent and qualified third-party financial auditor.
The Group-wide CSR, Supply Chain and Sourcing Policy are endorsed by senior management, shared with our suppliers and act as a guideline towards our stakeholders on how to adhere to our business principles.
Furthermore, the ESG Report 2025 was created and shared with stakeholders – enhancing transparency on the Group’s sustainability activities and ambitions.
Ethics – Social
The communities connected to Taché’s supply chain are stakeholders whose wellbeing is inseparable from the health of that chain. The Taché Foundation, established in 2021, funds long-term programmes in Botswana and Lesotho — two of the countries most directly linked to our diamond sourcing. Our approach is deliberate: sustained commitment to a small number of partners, with outcomes tracked through Track2Impact, our own accountability framework. We invest in relationships, not one-off donations.
In Botswana, the Foundation exclusively supports two safe houses run by the Botswana Gender-Based Violence Prevention and Support Centre, in Gaborone and Francistown. Since 2021, 349 individuals affected by gender-based violence have been sheltered there. In March 2025 we published our first Track2Impact case study on the partnership — an honest account of what it has achieved and where it has fallen short.
In Lesotho, the Beekeeping Centre of Excellence in Phamong, run with the Rural Self-Help Development Association, gives local farmers a route to market while supporting pollination and ecosystem regeneration.
Ethics – Environmental
Taché has supported Pure Ocean, a French foundation funding scientific research into deep-sea ecosystem protection.
We measure and publish our full greenhouse gas footprint every year, covering Scope 1, 2 and 3 across all five of our entities. Almost all of it — close to 99% — sits in the diamonds we purchase rather than in our own operations, which is why our reduction effort is directed upstream, at how and from whom we buy.
Taché joined the Science Based Targets initiative in 2024 and has submitted near-term and long-term targets, currently awaiting validation.
Our manufacturing facility in Surat achieved LEED Platinum certification in 2025, the highest level available. In Paris, connection to the district heating network eliminated the office’s direct gas emissions entirely.
Full figures, methodology and restatements are set out in our ESG Report 2025.
