Tiffany & Co aims for diamond supply chain transparency

14 January 2019

Tiffany & Co has announced it will etching diamonds with unique codes to show the provenance of each gem.

Under Tiffany's Diamond Source Initiative, each diamond sized 0.18 carats or larger will be be etched by laser with a unique code, invisible to the naked eye.

Diamond origin and region information will also be on show alongside displays of engagement rings and diamond jewellery in store.

Effective immediately, the brand will be sharing provenance information about each diamond, marking a significant step toward Tiffany’s 2020 sustainability goal to share the entire journey of all of its stones, including cutting and polishing workshop locations.

According to Anisa Kamadoli Costa, chief sustainability officer at Tiffany & Co, the initiative marks the brand’s commitment to transparency and promotes the protection of the environment and human rights in the diamond supply chain.

Currently the brand sources the majority (80-90%) of its diamonds from responsibly managed mines in Botswana, Canada, Namibia, Russia and South Africa, with the remaining diamonds sourced through trusted suppliers that meet the retailer’s Diamond Source Warranty Protocol, which restricts sourcing from countries with diamond-related human rights concerns, such as Zimbabwe and Angola.

Tiffany is not the first jewellery brand to focus on diamond provenance. In 2018, De Beers partnered with IBM to pilot a blockchain platform to trace the entire journey of its diamonds, as well as developing an app to verify diamonds mined in Sierra Leone to create a digital footprint for each stone.
