Japan, US Weigh Synthetic Diamond Facility to Strengthen Strategic Supply Chains
Industrial lab-grown diamonds for semiconductors and advanced manufacturing may be part of Japan’s planned $550 billion investment push into the US.
Japan and the United States are exploring the establishment of a synthetic diamond manufacturing facility in the US as part of Japan’s proposed $550 billion investment programme, according to a Reuters report citing sources familiar with the matter.
The proposed plant would focus on the production of lab-grown diamonds (LGDs) for industrial use, including applications in semiconductors, precision cutting tools and other advanced manufacturing technologies. Synthetic diamonds are increasingly viewed as a critical input for high-end industries due to their durability, thermal conductivity and performance advantages.
Discussions come amid rising concerns in Washington and Tokyo over global supply chain vulnerabilities, particularly the heavy reliance on China, which currently dominates synthetic diamond production. China has also imposed export controls on certain strategic materials, heightening the urgency for alternative supply sources.
The project could be among the early initiatives announced ahead of a potential visit by Japan’s prime minister to Washington. Companies such as Element Six, the industrial diamond arm of the De Beers Group, are said to be potential participants, while Japanese state-backed institutions may provide financial support.
Sources cautioned that talks are still at an early stage and no formal agreements have yet been finalised.

Botswana Looks Beyond Rough Diamond Sales, Eyes U.S. Jewelry Market
The Duty Exemption By US Presents An Opportunity For Domestic Jewelry Manufacturers In Gaborone To Bypass Traditional Middle-Market Hubs and Establish A Direct Pipeline To American Consumers
Grappling with a painful downturn in global rough-diamond demand, Botswana is pivoting its economic strategy: expanding up the supply chain directly into American retail shelves while leveraging its resource wealth to fund conservation and diversification.
Speaking on the sidelines of New York Climate Week, Bogolo Joy Kenewendo, Botswana’s Minister of Minerals and Energy, highlighted the southern African nation’s plan to capitalize on a 0% import-tariff rate to the U.S. market. The duty exemption presents an opportunity for domestic jewelry manufacturers in Gaborone to bypass traditional middle-market hubs and establish a direct pipeline to American consumers.
shift The push into value-added manufacturing comes as the world’s top diamond producer by value navigates a broader structural Diamond revenues have long formed the bedrock of Botswana’s post-independence balance sheet, underwriting universal secondary education and tuition-free university funding. However, recent market volatility has underscored the vulnerabilities of a mono-sectoral economy.
Under the Botswana Economic Transformation Programme (BETP)—an initiative spearheaded directly by President Duma Boko and his vice president—the government is directing resources toward manufacturing, agriculture, and broader mining sectors to reduce its heavy reliance on rough diamond sales.
To support its luxury exports, Botswana is recalibrating its brand narrative around origin, environmental stewardship, and social impact. The country recently announced a five-year extension of the “Okavango Eternal” partnership alongside De Beers Group and the National Geographic Society. The initiative aims to protect the ecological integrity of the Okavango River Basin while tying diamond purchases to conservation efforts.
With De Beers currently facing an impending ownership change, officials remain optimistic that any capital restructuring could bring additional funds into Botswana to accelerate its domestic economic transition.
