Summary in Plain Language
The essence of this news is that "Henan has obtained an industry trump card that no one else can take away, thanks to its synthetic diamonds." For decades, Henan has been the world's largest producer of synthetic diamonds, earning a meager income from selling industrial abrasives and rough diamond materials. Recently, it has coincidentally tapped into a new market opportunity worth hundreds of billions: AI chips have a dire need for high-end heat dissipation materials, and diamonds, with their superior thermal conductivity, have become the recognized "heat dissipation solution" for these chips. Henan, having built a complete industrial chain over 60 years, has just overcome its shortcomings in intelligent cutting and grinding technologies, resulting in a more than tripling of the net profits of its leading companies in the first half of the year. With 80% of China's synthetic diamond production capacity, Henan is poised to catch up with other central cities that lack such unique industries. However, as multiple provinces across the country have also entered the diamond industry, Henan's early advantage is not yet secure, and it still faces many challenges ahead.

Detailed Explanation
1. Why have synthetic diamonds, once sold at low prices, suddenly become so sought-after in the AI industry?
The reason is simple: AI servers require increasingly powerful computing capabilities, and the heat generated by these chips can be extremely high. Existing cooling methods (copper, aluminum, and ceramic) are no longer effective. Diamonds, with their five times higher thermal conductivity and non-conductive properties, are the perfect material for high-end cooling. The cost of synthetic diamonds was previously high due to their rarity, but now that Henan has reduced production costs, the industry is poised for explosive growth. Experts predict that the market for diamond cooling solutions could grow from 300 million yuan to tens of billions of yuan within five years, creating a completely new market opportunity.
2. Henan's success is not luck but the result of over half a century of investment in a unique industrial chain
Other regions cannot simply copy Henan's achievements. China's first synthetic diamond was produced in Zhengzhou in 1963, breaking foreign technological barriers. Over the years, Henan has developed a complete industrial chain, from raw graphite powder to the core equipment for diamond production, and everything in between. When a research team in Zhengzhou comes up with a new synthesis method, a manufacturing company in Xuchang can produce the necessary equipment within days, and suppliers in Nanyang can deliver high-purity materials the next day. Henan accounts for 80% of China's synthetic diamond production and half of the world's industrial diamond output. This industry cluster, built over 30 years, would be impossible to establish without such a foundation.
3. Henan's previous profits were meager, but now it can keep the entire chain's profits for itself
For a long time, Henan's synthetic diamond sales were low, with each ton of abrasive costing only a few tens of thousands of yuan. When diamond cultivation became more popular, the industry engaged in price wars, resulting in meager profits. Henan's synthetic diamond roughs had to be processed abroad, with 70% of the profits going to foreign companies. The newly launched domestic factory with an annual output of 400,000 carats has addressed this issue, allowing Henan to process the raw materials, cut and polish them into finished products, and produce high-end cooling solutions all locally. This has significantly increased profits for the leading companies.
4. Despite the surge in profits, the benefits are not yet fully realized as other provinces are also entering the market
While Henan's companies have seen their profits double, this is mainly due to the increase in the price of industrial diamonds, not yet from the heat dissipation business. Many industrial powerhouses, including Guangdong, Shanghai, Zhejiang, Hubei, and Fujian, have included diamond materials in their development plans and are investing in related technologies. Henan's previous weakness was a strong upstream presence but a weak downstream focus on high-value products. If it does not coordinate its industrial development effectively, its advantages could be diluted as other regions catch up.
5. This industry could be Zhengzhou's key to overtaking Wuhan and Hefei
For central Chinese cities, this industry is particularly significant. While Wuhan and Hefei have their own unique industries, Zhengzhou has lacked a prominent one. The diamond industry could become Zhengzhou's trump card, helping it to differentiate itself from other cities. With its extensive industrial foundation, Henan could develop a unique development path that sets it apart from other central regions.
