Conflict-Free Promise

At Iris + Mill, we believe that fine jewelry should be a reflection of beauty, integrity, and responsibility. We are deeply committed to ensuring that every diamond and precious metal used in our collections is sourced ethically and responsibly.

To honor this commitment, we partner exclusively with trusted, vetted suppliers who share our values and adhere to strict international compliance standards.

Natural Diamonds & The Kimberley Process

Every natural diamond featured in our jewelry is guaranteed to be conflict-free. We work solely with suppliers who rigorously comply with the Kimberley Process Certification Scheme (KPCS) and the System of Warranties established by the World Diamond Council.

  • What is the Kimberley Process? Established in 2003 by the United Nations, the Kimberley Process is a strict international monitoring system designed to eliminate the trade of conflict diamonds. It requires rough diamonds to be transported in tamper-resistant containers and accompanied by a government-validated certificate proving their ethical, conflict-free origin.

  • Our Guarantee: Through our strict vetting processes, we ensure that our natural diamonds are sourced entirely from legitimate channels not involved in funding conflict.

Lab-Grown Diamonds

To offer our customers beautiful alternatives that align with diverse preferences, Iris + Mill proudly features high-quality lab-grown diamonds.

  • Inherently Conflict-Free: Because lab-grown diamonds are created by scientists in controlled laboratory environments using advanced technology, they completely bypass the traditional mining supply chain. As a result, our lab-grown diamond collections are 100% conflict-free and have a traceable, clean footprint from origin to setting.

Social & Economic Impact

We believe that responsible sourcing extends beyond avoiding conflict—it also means supporting the communities and individuals behind the craftsmanship.

The legitimate diamond industry plays a vital role in developing nations around the globe. Revenue from ethically sourced natural diamonds helps fund critical public infrastructure, healthcare systems, and high-quality education, while providing stable employment in regions with limited economic opportunities.

By holding our supply chain to the highest ethical benchmarks, Iris + Mill helps support these positive global impacts while delivering exceptional jewelry you can feel proud to wear.
