On November 11, the cultivated diamond concept index climbed more than 5% at one point during intraday trading before closing with a gain of 4.67%. On the news front, several listed cultivated diamond companies recently issued price increase letters for rough cultivated diamonds, while another company has achieved small-batch commercialization in its heat dissipation business. Power Diamond responded that current market conditions for cultivated diamonds remain acceptable; the company's rough products are primarily exported to India, with prices kept confidential. Its terminal products include own-brand and factory stores, and terminal prices remain unchanged. Sifangda stated that the company can process heat sinks of approximately four inches and has already received small-batch sample orders, mainly targeting mid-to-high-end heat dissipation markets such as chips, with prices around tens of thousands of yuan per unit. Its affiliated enterprise is engaged in the own-brand loose diamond business, which shows no obvious peak or off-season. Huanghe Whirlwind confirmed that prices for rough products have already been raised, customer stickiness is relatively strong, and customers have basically accepted the price adjustment. The company's own-brand terminal stores generally run promotional activities during holidays, with specific details subject to individual stores.
