Sustainability
Responsibly sourced, thoughtfully made
At WILLIAM ÉDOUARD, we are committed to using ethical and sustainable practices across all areas of our work. We have taken rigorous steps to ensure that every gemstone used in our creations is ethically sourced and conflict free, and all WILLIAM ÉDOUARD packaging is made from 100% recyclable and reusable materials.
100% recycled gold and silver
All cast silver and gold in our creations comes from guaranteed recycled sources.
Conflict-free diamonds
Purchased in compliance with UN resolutions and the World Diamond Council System of Warranties.
Responsibly sourced gemstones
All other stones come from members of the Responsible Jewellery Council.
100% recyclable packaging
Every WILLIAM ÉDOUARD box and pouch is made from recyclable and reusable materials.

Recycled metals
Precious metals, given a second life
We take pride in the fact that 100% of the cast silver and gold used in our creations comes from guaranteed recycled sources, and is fully compliant with the LBMA Responsible Gold Guidance and the Organisation for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.
All other precious metal is sourced in a way that does not cause, support or benefit unlawful conflict, or contribute to serious human rights abuses or breaches of international law, and is subject to annual independent Conflict Metals audits.
Recycled silver can be reclaimed from old jewellery, photography and medical equipment, and scrap metals.

Diamonds and gemstones
Conflict free, and independently audited
All of our diamonds are conflict free and purchased in compliance with the United Nations (UN) resolutions and corresponding national laws. Our diamonds also adhere to the World Diamond Council System of Warranties Guidelines (WDC SoW) and the sanctions of the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC).
All other stones are sourced from suppliers that are members of the Responsible Jewellery Council (RJC). RJC members commit to and are independently audited against the RJC Code of Practices, an international standard on responsible business practices for diamonds, gold and platinum group metals. The Code of Practices addresses human rights, labour rights, environmental impact, mining practices, product disclosure and many more important topics in the jewellery supply chain.
