This report is an analysis of how ten leading luxury jewellery brands are addressing their corporate responsibility, particularly the sourcing of gemstones and precious metals. By benchmarking Boucheron, Buccellati, Bulgari, Cartier, Chanel, Chopard, Graff Diamonds, Harry Winston, Piaget and Van Cleef & Arpels, the report highlights various levels of corporate responsibility engagement. Boucheron and Cartier are the most active brands in trying to address the ethical, social and environmental aspects of their business throughout the supply chain, while the remaining brands are either inactive or only partially active. The results of the study suggest that the major reasons for the overall poor performance include an inadequate focus on traceability and pro-poor development issues, insufficient transparency, the emphasis on safety rather than opportunity, and limited attention to relationships. Includes twelve key findings.
