On November 11, the Cultivating Diamond Concept Index rose more than 5% in the intraday period and closed with a 4.67% increase. Some listed companies that cultivate diamonds have recently issued rough price increase letters, and the cooling business has been commercialized in small batches. Power Diamond claims that rough cultivated diamonds are mainly exported to India, the price is confidential, and the terminal price has not changed; Sifangda claims that it can process about four inch heat sinks, and the price is about tens of thousands of yuan per piece; the Yellow River Cyclone claims that rough products have increased prices, and large single crystal products have increased 10% since November 1, 2026, operating costs have increased dramatically due to rising production costs and exchange rate appreciation; Zhongbing Hongjian claims that sales and shipments of cultured diamonds are normal. The industry claims that the cooling business has yet to generate large-scale revenue. Large-scale mass production depends on the progress of downstream applications. The biggest problem in the industry is still improving profitability, and the Yellow River Cyclone is still losing money.
