J.R. Dunn Jewelers Introduces Single Source™: Blockchain-Backed Natural Diamonds with Verified Origins

LIGHTHOUSE POINT, Fla., April 23, 2025 /PRNewswire/ -- J.R. Dunn Jewelers proudly unveils Single Source™, a groundbreaking collection of natural diamonds backed by blockchain technology—delivering full transparency, ethical sourcing, and a digital origin story for every stone.

Each Single Source™ diamond is mined in ethically committed countries—Botswana, Namibia, or South Africa—and is digitally traceable through the Tracr™ blockchain platform. Every diamond comes with a Blockchain Signature Card and scannable QR code, allowing clients to view its verified journey from rough to polished. Unlike traditional diamond supply chains, Single Source™ offers unmatched confidence in a diamond's provenance.

"When I saw the opportunity to represent natural diamonds that create a positive impact in the communities where they're mined, I knew it aligned perfectly with our values." — Sean Dunn, Vice President

Thanks to direct partnerships with a triple sightholder with cutting factories at the source, Single Source™ diamonds are not only 100% natural and ethically sourced—they're also competitively priced. Each country represented in the collection is rich in diamond heritage and benefits directly from the industry through job creation, education, and infrastructure development.

All loose diamonds and diamond solitaire jewelry in the collection are certified Single Source™, with traceability to a specific country of origin. J.R. Dunn's commitment aligns with the G7-led global push for stricter sourcing standards and mine-level transparency. By the end of 2025, all multi-stone jewelry in the collection is expected to be fully traceable to a single country of origin.

This first-of-its-kind experience in South Florida allows clients to explore their diamond's full story—from the country it came from to seeing it in its original rough form and final cut—offering more than just sparkle, but a story they can believe in.

"Single Source™ diamonds are perfect for heirloom pieces. Each one tells a story that's uniquely yours." — Sean Dunn
