A partnership between Botswana-based diamond manufacturer Zoe Diamonds and Florida retailer J.R. Dunn Jewelers has resulted in the first direct export of Botswana-cut and polished diamonds to the United States, bypassing traditional rough diamond supply chain layers. This development signals a shift in how retailers can source polished diamonds with full traceability, offering overseas jewelry buyers a new model for securing ethically sourced, value-added stones directly from the source country.
Supply-chain impact
The partnership bypasses the conventional rough diamond market, where retailers rarely purchase directly from primary tenders. Historically, rough diamonds are sold by producers like Okavango Diamond Company (ODC) to diamantaires or sightholders, who then sort, cut, polish, and sell to retailers. By sourcing rough through ODC, manufacturing in Gaborone, and exporting polished stones directly to the U.S., Zoe Diamonds and J.R. Dunn Jewelers have created a streamlined, vertically integrated channel that reduces intermediaries and enhances supply chain transparency.
First shipment details
The initial shipment, completed in December 2025, comprised two polished diamonds totaling 2.91 carats. The stones were sourced through ODC, cut and polished in Botswana, and exported directly to the U.S. This small-scale transaction demonstrates the feasibility of direct polished diamond exports from Botswana to American retailers, potentially paving the way for larger volumes and more frequent shipments.
Traceability and blockchain tracking
Zoe Diamonds employs blockchain technology to track each diamond from mine to certification, providing documented traceability throughout the supply chain. This feature is increasingly important for overseas buyers seeking verifiable origin and ethical sourcing credentials. The partnership also inspired a jewelry concept called "TWO FROM ONE," which uses two diamonds cut from a single rough crystal to emphasize shared origin and transparency.
What buyers should watch
Overseas jewelry importers and retailers should monitor this direct sourcing model as Botswana continues to promote beneficiation initiatives aimed at expanding local cutting, polishing, and manufacturing. Direct partnerships between manufacturers and retailers could reduce costs, improve traceability, and offer competitive pricing for polished diamonds. However, challenges remain, including quality assurance and logistical hurdles, as noted by J.R. Dunn Jewelers' president Sean Dunn, who acknowledged there were no guarantees in this new sourcing approach.
China sourcing context
While this partnership is centered on Botswana and the U.S., it reflects a broader trend in the diamond supply chain toward vertical integration and traceability. Chinese jewelry manufacturers and trading companies sourcing diamonds for OEM/ODM production may find opportunities to collaborate with Botswana-based cutters and polishers, especially as demand for ethically sourced, blockchain-tracked diamonds grows in global markets. Direct relationships with African producers could offer competitive advantages in transparency and cost.
