We are constantly looking at further increasing the overall sustainability performance of our collections and relentlessly work on our key materials and sourcing partners.In this regard, we are proud to feature the black opals used in the Green Carpet collection in 2015. These stones were sourced from a well-established family mining entity in Australia: the Aurora Gems opal mine, situated in the remote outback. The owners have been involved in the opal business all their lives and manage the whole process from mining to polishing and selling of the finished stones. Nothing is outsourced, which ensures that the opals are 100% traceable to their origin.In 2016 Chopard has marked a further milestone in its Journey to sustainable luxury by announcing yet another industry pioneering initiative. To celebrate the beginning of this new phase of The Journey, Chopard developed a unique partnership with Gemfields, the world’s largest producer of coloured gemstones, to unveil a capsule collection of Green Carpet High Jewellery masterpieces featuring responsibly sourced emeralds. Eco-Age, experts in mining practices and Chopard’s partner in developing The Journey to Sustainable Luxury, validated the mining site and parent organisation against the GCC Principles of Sustainable Excellence.By working together with trusted suppliers, Chopard sets an example of best practice in the mining of coloured gemstones, demonstrates leadership in the forging of industry alliances and continues to support local communities in the most remote regions where these extremely rare raw materials are mined.One of the goals of The Journey is to create sustainable supply chains, including the sourcing of gold, emeralds, opals and more. As part of The Journey, we continually review our supply chains to ensure the procurement of responsibly-sourced stones. Towards this end, and in light of the escalating Rohingya crisis in Burma, Chopard have taken the decision to cease sourcing Burmese gemstones with immediate effect. We take our commitment to the highest standards of ethical sourcing very seriously and will continue to monitor the situation in Burma to help ensure that our principles are not compromised, now or in the future.
