Behind 95% of Global Output: Technological Breakthroughs! The 17th China Diamond Technology Seminar 2025 Unlocks Full-Industry Chain Potential
When China Dominates 95% of Global Diamond Production, This Top-tier Seminar is Shaping the Future of Technology!
In 2025, The 17th China Diamond Technology Seminar kicked off as scheduled, gathering global industry elites and top scholars. From industrial scale to technological breakthroughs, from basic research to cross-border applications, it comprehensively demonstrates China's absolute dominance and innovative vitality in the diamond field — this is not just an academic exchange event, but a powerful declaration of China's leadership in global diamond technology!
Chinese Power: Underpinning Over 90% of the Global Diamond Industry!
Numbers speak volumes: In 2024, Chinese manufacturers produced 22.4 billion carats of synthetic diamonds, accounting for 95% of the world's total output — that means 9.5 out of every 10 synthetic diamonds globally are made in China! On the export front, from 2020 to 2024, China exported a total of 20.4 billion carats of diamonds, with 4.5 billion carats shipped to the global market in 2024 alone, solidifying its position as the core pillar of the global diamond supply chain.
In the diamond tools sector, China's exports are equally impressive: From 2020 to 2024, exports of diamond tools for grinding and polishing reached 127 million kilograms, while cutting diamond tools exports soared to 510 million kilograms! These tools are widely used in key fields such as building materials, automotive manufacturing, aerospace, and electronic semiconductors, becoming the indispensable "hard core" of global industrial production.
Gathering Top Scholars: Unlocking Diamond Technology's "Deep End" and "New Tracks"
The academic weight of this seminar is evident from the cutting-edge reports delivered by renowned experts — focusing on basic research and technological breakthroughs to open up more possibilities for diamond applications:
- Professor Li Chengming (University of Science and Technology Beijing): Presented "Characteristics and Control Methods of Diamond Dislocation". Dislocation control is crucial for improving diamond crystal quality, directly determining its application potential in high-end fields, and providing theoretical support for the preparation of high-performance diamond materials.
XRT: The most effective nondestructive method for observing grain boundaries & crystalline imperfections
Phase space of hardness (GPa) and Fracturetoughness (MPa·m1/2)
- Professor Sun (Shanghai Jiaotong University): Shared "Research on Laboratory-Scale Monocrystalline Diamond Preparation via HFCVD". As one of the core technologies for producing high-quality monocrystalline diamonds, advances in HFCVD will promote the large-scale application of diamonds in precision electronics, optics, and other sectors.

Surface Reaction Process
- Professor Wang Ya (University of Science and Technology of China): Detailed "Preparation and Applications of Diamond Color Centers", unlocking diamond's "quantum potential"! Through three mainstream methods — ion implantation (implanting impurity ions such as nitrogen and silicon into the diamond lattice followed by high-temperature annealing), high-pressure high-temperature (HPHT) synthesis, and chemical vapor deposition (CVD) — precise control of impurity concentration and lattice defects enables diamond color centers to become key players in quantum technology. They serve as solid-state qubits for quantum computing, ultra-high-sensitivity detectors for quantum sensing (enabling intracellular magnetic field detection and geological exploration), high-security single-photon sources for quantum communication, and even find applications in long-duration, high-density, low-power-consumption diamond compact discs (CDs), boasting immense cross-border potential.
Quantum Sensing Based on Spin Coherence
Diamond CD Storage
- Professor Wenfeng Ding (Nanjing University of Aeronautics and Astronautics): Focused on "Mechanism of Ultrasonic Vibration-Assisted Grinding for Tenons of Superalloy Blades in Aero-Engines", advancing diamond tools into the "chokepoint" field of aerospace. Superalloy blades are core components of aero-engines, and the machining precision of their tenons directly affects engine performance. With ultra-high hardness and wear resistance, diamond tools have become the ideal choice for this field, demonstrating the industrial application strength of Chinese diamond technology.
