Ethical Sourcing & Sustainability

Tiffany & Co. is committed to assuring the integrity of our sources and maintaining the highest standards of social and environmental responsibility. As long-time leaders in the jewelry industry, we work to advance rigorous responsible mining standards. We also invest in diamond-producing countries, actively advocating for preservation efforts and effective government oversight.

Tiffany & Co. is a leader in working toward a more responsible jewelry industry.


That work began when we opposed the development of a gold mine that threatened Yellowstone National Park.


We led the effort to seek United States Congressional approval of U.S. participation in the Kimberley Process.


We were the first jeweler to embrace the objectives of the No Dirty Gold campaign in 2005, a promise not to source gold from mines that do not meet certain social and environmental standards.


Our stones come primarly from mines in Australia, Botswana, Canada, Namibia, Russia, Sierra Leone and South Africa. Further, we cut and polish the vast majority of these diamonds in our own facilities around the world to maintain the highest quality standards, ensure compliance with our Social Accountability Program and support beneficiation in Botswana and Namibia.

The Kimberley Process

Tiffany diamonds are mined only in those countries that are full participants in the Kimberley Process Certification Scheme. The Kimberley Process is an international cooperative monitoring system created to eliminate the trade of “conflict diamonds”—rough diamonds that are smuggled by rebel movements to finance wars against legitimate governments—from the global supply chain.

Diamond mining, cutting and polishing should be important engines of social development and economic growth for the countries that host these facilities, and producing countries rightly deserve a larger share of the profits of the diamond supply chain.

Responsible Mining

Tiffany believes that traceability is key to ensuring that mines are operated in environmentally and socially responsible ways. We have established our own rigorous standards for responsible mining that guide our decisions about which mines we directly source from. In many cases the output of these mines is delivered directly to Tiffany’s own diamond cutting and polishing facilities.
