Key facts
- China's lab-grown diamond producers aim to pivot from jewelry to high-tech applications like semiconductors and AI infrastructure.
- Demand for synthetic diamonds in chips and thermal management could become the industry's next major growth engine.
- Companies like Huawei, TSMC, and Lenovo are exploring or using synthetic diamonds for chip cooling applications.
- Gross profit margins for industrial diamonds are about 50%, compared to 30%-40% for gem-grade diamonds.
China's lab-grown diamond producers are increasingly looking beyond the jewelry market to supply advanced materials for semiconductors, AI servers, and other high-tech applications. This strategic shift is driven by intensifying competition and price pressures in the gem market, with companies aiming to increase the share of functional materials in their production. The move could give China a strategic advantage in the US-China technology rivalry, particularly if synthetic diamonds become crucial for semiconductors and thermal management in AI infrastructure. Companies and analysts see demand from sectors like chips, thermal management, and quantum technology as the next major growth engine, due to the unique properties of synthetic diamonds that can enhance advanced electronics and computing systems. This trend aligns with the surge in demand for data center capacity fueled by AI, which is projected to significantly increase electricity consumption by 2030.
