[Is the price of rough lab-grown diamonds rising? Huanghe Tornado’s response: True] On November 4, market news said that recently, Huanghe Tornado’s wholly-owned subsidiary Lianyi Diamond (Henan) Co., Ltd. issued a price adjustment letter for large single crystal products. Affected by factors such as the recent increase in production costs and the continued appreciation of the exchange rate, the company's operating costs have increased significantly. Starting from November 1, 2026, the price of large single crystal products (rough cultivated diamonds) will be increased by 10% based on the original price. In response, Huanghe Tornado said that the price increase news was true. The company's large monocrystalline products are only sold by its subsidiary Lianyi Diamond (Henan) Co., Ltd., and the price increase letter was also issued by the subsidiary. The price is determined based on market conditions. This price increase is the second price increase this year. The first price increase was carried out in March. The company's products cover the entire industry chain of superhard materials, including diamonds, cultured diamonds, etc. Except for large single crystal products, there has been no price increase for other products.
