For 100 years, one company controlled the diamond supply on earth. Then factories in a Chinese province most Americans have never heard of changed everything.

This video traces how Chinese industrial diamond factories dismantled a century-old monopoly, crashed wholesale prices by 95%, and destabilized the economies of entire nations.

Covered in this video: China's Cold War era synthetic diamond program, CVD vs HPHT reactor technology, the Henan province supply chain, De Beers financial collapse, Botswana's economic crisis, the American engagement ring market shift, lab grown resale values, and what this means for anyone buying or holding a diamond in 2026.
