On January 27th, individuals with inside knowledge of the situation disclosed that Japan's ambitious $550 billion investment plan encompasses the establishment of a man-made diamond production facility in the United States as a pivotal project. This strategic initiative is geared towards boosting the output of materials that are vital for chip manufacturing and high-precision industrial processes.

According to two well-placed sources, these projects could be among the initial announcements, with the potential for an early reveal in March, preceding Japanese Prime Minister Sanae Takaichi's scheduled visit to the US. One of the sources highlighted that the United States is keen on expediting the domestic production of man-made diamonds by collaborating with Japanese firms to forge a robust US-Japan supply chain.

It has been reported that the man-made diamond venture involves Element Six, a subsidiary of the renowned De Beers Group, which is a global titan in the diamond industry. When approached for comment, Japan's Ministry of Economy, Trade and Industry remained tight-lipped about the specific projects, stating that ongoing negotiations with the US regarding the advancement of the project list are in progress, and no final decision has been reached as of yet.
