Diamond giant Tiffany & Co. has announced that it will begin sharing with consumers the region or countries of origin of its newly sourced, individually registered diamonds — a significant step for diamond transparency — and by 2020, their craftsmanship journey — an industry first.

With its Diamond Source Initiative, Tiffany is tracing each of its individually registered diamonds (0.18 carats and larger) by a unique “T&Co” serial number etched by laser and invisible to the naked eye, and providing consumers geographic sourcing information specific to their diamond. Beyond general assurances of “conflict free,” Tiffany believes that knowing provenance is critical to ensuring its diamonds are among the most responsibly sourced in the world.

Effective Today:

Provenance information will be merchandised in Love & Engagement case lines in Tiffany stores around the world, alongside a selection of diamond rings with their individual provenance clearly displayed. In addition, geographic sourcing information for all individually registered diamonds will be made available to consumers via Tiffany & Co. sales professionals and customer service.
Tiffany & Co. is committing to 100 percent geographic transparency for every newly sourced, individually registered diamond, and will not source any diamonds with unknown provenance (even if responsible sourcing is assured) moving forward.

In Q1 2019:

Tiffany will begin including provenance on the Tiffany Diamond Certificate for individually registered diamonds, alongside the stone’s other specifications, information not made available on other industry lab reports or by other global luxury jewelers.

In 2020:

Tiffany will begin sharing details on each gem’s craftsmanship journey (such as cutting and polishing workshop location) in addition to provenance.

“Diamonds, formed up to 3 billion years ago and brought to the earth’s surface by a miracle of nature, are symbols of the most important moments in our lives. There should be nothing opaque about Tiffany diamonds,” said Tiffany CEO Alessandro Bogliolo. “Our clients want and deserve to know where their most valuable, most cherished diamond jewelry is from, and how it came to be.”

Tiffany’s Diamond Source Initiative builds on growing industry efforts to produce jewelry ethically. Last year, IBM launched its TrustChain initiative — a cross-industry collaboration that uses blockchain to trace the provenance of finished pieces of jewelry across the supply chain, and is designed to halt the illegal trade of so-called “blood diamonds” and promote ethical jewelry, in general. The collaborators represent the entire diamond and jewelry supply chain: Rio Tinto Diamonds (diamond supplier for Proof of Concept only), Leach Garner (precious metals supplier), Asahi Refinery (precious metal refinery), Helzberg (US jewelry retailer) and the Richline Group (global jewelry manufacturer); the process is enabled by IBM’s blockchain technology and UL’s independent, third-party verification services.

With its new initiative, Tiffany aims to bring a new level of transparency to its diamond supply chain. In cases where provenance is unknown — such as heritage stones that predate this policy — Tiffany will provide confirmation that the diamond was sourced with industry-leading practices. Tiffany says its standards exceed the Kimberley Process Certification requirements for rough diamonds and, for polished stones, mandate compliance with the company’s Diamond Source Warranty Protocol. For example, in the case of one trusted supplier with several responsibly managed operations, diamonds may be designated ‘Botswana sort.’ The majority of these diamonds were mined in Botswana, as well as in select mines in Namibia, South Africa or Canada. For ‘Botswana sort” stones, provenance is the above grouping of countries, procured as an aggregated parcel of rough diamonds from a specific, limited group of mines in Southern Africa and Canada.

“Tiffany & Co. has long been committed to diamond traceability, and going above and beyond industry norms to promote the protection of the environment and human rights,” said Anisa Kamadoli Costa, chief sustainability officer at Tiffany & Co. “A transparent journey of responsible sourcing reflects the many positive and far-reaching benefits along every step of the diamond supply chain.”

Tiffany & Co. is unique among global luxury jewelers in owning and operating its own diamond polishing workshops around the world — where 1,500+ Tiffany artisans ensure superlative diamond quality and craftsmanship. To highlight this competitive difference, by 2020, Tiffany will also share the craftsmanship journey of its diamonds along with its provenance.

Since 1999, Tiffany has been investing in vertical integration and prioritizing its supply chain transparency. Approximately 80-90 percent of Tiffany’s individually registered diamonds (by volume) have been supplied through Tiffany operations in Belgium, Botswana, Mauritius, Vietnam and Cambodia, where craftspeople plan, saw and/or cut and polish rough diamonds from known, responsibly managed mines, most of which are in Botswana, Canada, Namibia, Russia and South Africa. For the remaining 10-20 percent, Tiffany’s trusted suppliers of polished diamonds have complied with Tiffany’s Diamond Source Warranty Protocol, which warrants that the diamonds did not originate in countries with diamond-related human rights concerns, such as Zimbabwe and Angola (even though these diamonds are accepted under the Kimberley Process).

From today, those suppliers will be required to go beyond a warranty of “conflict-free” to affirmatively state the geographic source of any polished diamonds sold to Tiffany including region or countries of origin.
