CORPORATE SOCIAL RESPONSIBILITY

Sustainability is at the heart of Dianco’s values, representing our commitment to doing business responsibly. For us, sustainability means considering the impact of our actions on the community, environment, and economy. It's about finding a balance that ensures we can meet the needs of today without compromising the ability of future generations to meet their own needs.

We are proud members of the Responsible Jewellery Council (RJC) because they share a mission centered on sustainability within the jewelry and watch industry. Moreover, all our factories certified by the Best Practice Principles (BPP), we are steadfast in our commitment to achieving carbon neutrality. We created an initiative focused on women's empowerment and support by facilitating daycare services for the children of our Namibian employees, in line with our mission of providing more opportunities to our female workers.

On the other hand, as active members of the Watch and Jewellery Initiative 2030, we're engaged in collaborative efforts to shape the future of the jewelry industry. Furthermore, being part of iTraceIt and Tracr allows us to further enhance transparency and traceability in our supply chain, empowering consumers to confidently track the journey of their diamonds.

Through these initiatives and partnerships, we are dedicated to fostering trust, sustainability, and ethical standards throughout the jewelry industry. At Dianco, sustainability isn't just a box to tick; it's an ongoing journey of improvement and responsibility that we are committed to every step of the way.
