Ethical Sourcing is number one priority at Whitehouse Brothers, so we ensure all suppliers are in compliance with the Kimberly Process and are current Diamond Sightholders. Having a Diamond Sightholder is an important extra step to the process, because it can guarantee that every diamond we sell is in adherence to international law and the Kimberly Process. Sightholders are put under strict requirements to ensure they do not buy diamonds from areas of conflict, and do not endanger the welfare of individuals. Each diamond we sell is guaranteed to follow the international best practices for environmental and human rights. If you are interested in learning more, please feel free to contact us or look further into the Kimberly Process.
