Summary of Cultivated Diamond Industry Conference Call Industry Overview - The cultivated diamond industry in China is experiencing significant growth opportunities due to tax policy adjustments that have narrowed the price gap between domestic and international markets. [1] - The rough diamond prices are expected to bottom out and rebound by the end of 2025, with a pre-Spring Festival increase of approximately 10%-15%, driven by inventory clearance and rising costs. [1][2] - The high-temperature high-pressure rough diamond market is currently in a state of supply shortage, while prices in the CVD (Chemical Vapor Deposition) sector have also shown a positive rebound. [1][3] Key Insights and Arguments - CVD manufacturers are focusing on producing standard sizes to enhance their bargaining power, with an increase in the supply of large carat stones and the widespread adoption of automated cutting and polishing techniques. [1][3] - The market for 1-carat and above diamonds remains stable, while prices for stones below 0.5 carats have slightly decreased. However, demand and trading volumes have significantly increased, leading to an active market. [1][3] - There is a rapid growth in demand for cultivated diamond products in both domestic and international markets, with a notable 61% market share of cultivated diamonds in U.S. wedding rings. [1][4] Functional Diamond Applications - Progress has been made in the field of functional diamonds, particularly in heat dissipation and packaging applications, with several listed companies sending samples for verification to major firms like NVIDIA, BYD, and SMIC. [1][4] - The NVIDIA B20 server has adopted diamond heat dissipation technology, achieving a 15% increase in computing power, marking a significant advancement in the commercialization of diamond applications. [1][4] Market Dynamics - The new regulations at the Shanghai Diamond Exchange, effective November 2025, have replaced the previous tax structure with a 13% VAT, leveling the price space between imported and domestically processed cultivated diamonds. [2] - The cultivated diamond prices are expected to rebound by the end of 2025, with a projected increase of about 10% for 1-carat and 1.5-carat stones, and approximately 15% for rough diamonds. [2][11] - Despite being in a retail off-season, the global market remains stable, and demand for finished products is expected to continue increasing, leading to stable prices. [2][11] Production and Capacity Expansion - Domestic companies are actively expanding production capacity, with several firms planning to increase their output significantly. [12][13] - The focus of new capacity additions is primarily on industrial-grade diamonds, although there is consideration for maintaining flexibility to switch to consumer-grade production. [14][15] - The market for functional diamonds is anticipated to reach a trillion-level market space, significantly larger than the consumer-grade market, as the commercial acceptance path becomes clearer and production costs decrease. [13][15] Competitive Landscape - Domestic enterprises are on par with global competitors in the industrial and semiconductor-grade functional diamond sectors, with advantages in mass production capabilities and collaboration efficiency with application partners. [8][9] - Indian companies are rapidly expanding their CVD production capacity, leveraging existing channel advantages to catch up with domestic firms. [8][9] Challenges and Future Outlook - The main challenges in the commercialization of diamond films include equipment operation stability, continuous optimization of diamond growth processes, and the design and validation of thermal management applications. [10] - The industry is expected to continue evolving, with ongoing technological advancements and market adaptations driving growth in both cultivated and functional diamond sectors. [10][11]
