Huifeng Diamond's "30CM" hit the limit up, the company responded: they are not aware of whether the product is applied in the diamond heat dissipation field.

On June 2nd, the cultivated diamond sector saw a significant increase. Wind data shows that as of the close of June 2nd, the Wind Cultivated Diamond Index rose by 6.08%, with Huifeng Diamond's stock price closing at 80.6 yuan per share, a 30% increase at the close. In response to the sharp rise in stock prices, Huifeng Diamond exclusively told a reporter from China Securities Daily that the cultivated diamond industry is in a recovery phase. Since 2026, the industry has undergone two price adjustments with price increases ranging from 5% to 15%. Additionally, there has been a noticeable increase in the price of tungsten since last year, which is a key material used in the production equipment for cultivated diamonds. The rise in tungsten prices has a certain impact on the cost of equipment procurement for cultivated diamonds. The recent significant increase in the cultivated diamond sector may be related to the potential for diamonds to replace materials such as copper and aluminum in high-power, high-energy-consuming products. "Diamonds as a heat dissipation material may gradually enter the AI race, with some leading AI companies already experimenting with heat sinks made of diamonds. However, the company does not directly interface with customers and does not know whether the products manufactured by the company are used in these areas," Huifeng Diamond told the reporter.
