How do I know the provenance of my individually registered Tiffany diamond?

For all newly purchased diamond rings as of 9 January 2019, the provenance of each individually registered Tiffany diamond will be available in store or through our Client Care team—and soon on our Tiffany Diamond Certificates. Tiffany has long supported responsible sourcing. We are committed to ensuring that our diamonds do not originate in any countries with diamond-related human rights concerns, even if those countries adhere to the Kimberley Process. Effective in 2019, Tiffany will only source diamonds with known region or countries of origin. Tiffany has a zero-tolerance policy towards conflict diamonds.
