Synthetic diamonds seen as next US-China supply chain flashpoint

Industry analysts warn that synthetic diamonds could become a critical material in semiconductors and thermal management for AI data centers, and China's dominance in synthetic diamond production may leave the United States exposed to another supply-chain bottleneck. Debate is growing over whether Washington should treat lab-grown diamonds as a strategic resource alongside chips and rare earths.

Why now: Rising concern that AI infrastructure demand could make Chinese synthetic diamond production a strategic vulnerability for the U.S.
