Signet Becomes a Link in De Beers’ Blockchain
The jeweler is the first retailer on the end of the Tracr trial run, though it will not be the only.

Akron, Ohio--Signet Jewelers Ltd. has become the first jewelry retailer on the end of De Beers’ trial blockchain run, though it will not be the only.
Trademarked as “Tracr” by De Beers Group, the blockchain platform is being developed in partnership with BCG Digital Ventures, an arm of Boston Consulting Group.
It will be used to digitally track diamonds from their origin as rough stones at De Beers’ mines through the manufacturing process to the retailer, creating a digital certificate for each diamond registered on the platform that includes its key attributes (carat weight, cut, color, clarity, etc.) and shows its path—the diamond was mined here, went to this manufacturer for cutting, etc.
De Beers and Signet said their partnership initially will focus on diamond jewelry, eventually expanding to include smaller-sized goods.
When asked if Signet would be marketing and selling the Tracr-tracked diamond jewelry to consumers under a specific name, as Helzberg Diamonds is set to do with the diamond jewelry being tracked through TrustChain, Signet Jewelers Vice President of Corporate Affairs David Bouffard said the Signet and Tracr teams will work together to figure out how it can use the platform to build customer-facing solutions in the future.
Signet, which owns Kay Jewelers, Jared the Galleria of Jewelry and Zales stores, is the world’s largest retailer of diamond jewelry both by volume and by value and is the first retailer to participate in Tracr.
Yulianna Vilkos, a De Beers spokeswoman, said the company currently is in talks with other major industry stakeholders, including other retailers, about participating in the program.
Though De Beers announced earlier this month that it already has tracked 100 “high-value” diamonds using blockchain, the Tracr pilot is not officially slated to launch until later this year.
