Bullish on the cultivation of diamonds in 2022.

Continuing to be bullish on the cultivation of diamonds and monocrystalline silicon raise prospect in 2022. We believe that the significant increase in the company's profitability is mainly driven by the improvement of the product structure due to the increase in the proportion of the diamond cultivation business, as well as the increase in the average price of products driven by the high prosperity of the diamond cultivation and monocrystalline silicon industry. In 2022, we continue to be bullish on the price increase prospects of cultivation diamonds and monocrystalline silicon. Regarding the cultivation of diamonds, due to the current geopolitical conflicts, sanctions by European and American countries on Russian natural diamonds may lead to insufficient supply and price increases. Since there is a certain degree of anchoring relationship between the price of cultivated diamonds and natural diamonds, it is expected that the price increase of natural diamonds will provide good support and bottoming for the price of cultivated diamonds. At the same time, the decline in the supply of natural diamonds is also expected to drive some demand to shift to cultivated diamonds, thereby accelerating the penetration of cultivated diamonds. As for monocrystalline diamond, it is expected that industrial diamonds will still be in short supply in 2022, as the industry's new six-mirror pressing machines will continue to be mainly used for the production of cultivated diamonds, so the product price is expected to remain high.
