    Yes, they all are. Because we control our entire supply chain, we can make sure that all of your stones are sustainable.

    We produce our finished products as close to source as possible. We also operate a workshop in Bogota, Colombia, employing local craftspeople on a fair and equitable basis.

    We carefully monitor the entire length of our supply chain and only work with partners who have a detailed policy relating to their own supply chains. As proud members of the Responsible Jewellery Council and the National Association of Jewellers, we strive to ensure that we operate in an ethical and considerate fashion.

    In 2020, we opened our Colombian subsidiary, London DE SAS, in the heart of the emerald district of Bogota. This helps us to ensure we’re buying our stones and materials from the top of the supply chain and know the exact provenance of our materials.

    All of our stones come with full paperwork and certification.
