Some of Europe’s best-known luxury jewelers have been accused of failing to ensure that the gold and diamonds on their shelves were sourced ethically, with many reportedly lacking adequate policies to stamp out human rights abuses. In a new report by Human Rights Watch, the group says UK brand Boodles, Switzerland’s Chopard and Germany’s Christ were all ranked as "weak" in terms of their approach to ethical sourcing. The brands had failed to make public crucial information about supply chain and human rights due diligence, despite their legal responsibility to do so.
