China blockades artificial diamonds, and the tools to make them
by Inside China Business [12-23-2025].
China has a monopoly on the production of artificial diamonds, producing 95% of the world's total.
The lab-grown diamond industry is booming, and transforming precision manufacturing, semiconductors and computing, aeronautics and aerospace, and energy industries.
China's Ministry of Commerce has effectively "blockaded" the sale of artificial diamonds, or the equipment and tools to make them, for industrial and especially dual-use purposes.
Chinese diamond suppliers are still legally allowed to supply global jewelry markets with lab-grown stones. But high-end manufacturing and especially defense contractors are faced with an existential problem: buy finished products from China, or go without, or build the entire industry from scratch.
