A new initiative unites top luxury brands and mining companies around a shared vision for the gemstones and jewellery industry

Today marks the culmination of five years collaboration between the Coloured Gemstone Working Group and TDI Sustainability as we unveil the Gemstones and Jewellery Community Platform.

Unique in the industry, the Platform will offer free resources and tools, created and tested through the engagement of over 150 businesses over the last three years. The resources and tools will support businesses of all type, size, and shape, in their efforts to build knowledge and capacity around key sustainability topics, implement their learning, and demonstrate their efforts towards improving social, environmental, and governance performances.

The initiative focuses on learning and on continuous improvement; an acknowledgment that real change takes time, but that together we can move one step further along the journey towards a sustainable industry. 

The Coloured Gemstone Working Group is a unique alliance between the world’s leading luxury jewellery brands and mining companies: Tiffany & Co., Swarovski, Richemont, The Muzo Companies, LVMH, Kering, Gemfields and Chopard, united by a common vision for a more accountable, transparent and responsible gemstones and jewellery industry.

As technical advisor and facilitator to the Group, TDI Sustainability’s CEO, Dr. Assheton Stewart Carter, says, “The responsible sourcing movement is a powerful force that has the potential to bring transformative change and improve the lives of many people deep in the coloured gemstone supply chain. The objective must be to make sustainability familiar and accessible to even the smallest businesses and the individual craftsperson”.

The CGWG has been collaborating, and continues to collaborate, with industry bodies and associations including the Responsible Jewellery Council (RCJ) and the World Jewellery Confederation (CIBJO), in an effort to avoid duplications and inefficiencies and contribute to the harmonisation of the industry, and promotes the implementation of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

Carter adds, “To have a truly sustainable footprint, industry collaboration is the only way forward. The CGWG has taken a step to provide the tools and information to help achieve this goal, but it is only the first step. The next steps in this journey need to be taken in tandem with others and we invite businesses large and small as well as consumers to engage in this vital process and join our Platform”.
