Core Advantages of the Exhibition

I. Anchoring the Global Industrial Core Location, Enjoying the Dividends of a Hundred-Billion-Level Market

China is the undisputed production center and technology source of the global lab-grown diamond industry — rough production capacity accounts for about 63% of the world, of which about 80% is produced in Henan. In 2026, China's lab-grown diamond market officially enters a hundred-billion growth cycle, and global production capacity and innovation momentum continue to gather in China. LGD&E 2026 is based in Shanghai, an international trade hub, and with an exhibition scale of 30,000 square meters, it gathers global leading enterprises, scientific research institutions, and professional buyers, helping exhibitors precisely position themselves in the fastest-growing core market in the world and share the dividends of the hundred-billion-level industry.

II. Relying on the Top Platform Effect of Shanghai as an International Exhibition Capital

Shanghai is one of the cities with the most active exhibition activities in the world, with a total exhibition area of over 19.3 million square meters, firmly ranking first among major global exhibition cities; the proportion of international exhibition area continues to remain above 80%, and the world's top ten exhibition groups have all settled in Shanghai. As the permanent venue of the CIIE, the National Exhibition and Convention Center (Shanghai) holds an annual total area of exhibitions, conferences, and events of over 8 million square meters, accounting for nearly 40% of the city's exhibition scale, and hosts more than 20 large-scale professional exhibitions of 100,000 square meters or more each year. LGD&E 2026 held here will fully rely on the professional operation capability and global influence of this mature platform to provide exhibitors with one-stop high-standard guarantees from venue hardware to exhibition services.

III. Full Industrial Chain Coverage, Precise Docking of Diverse Procurement Needs

This exhibition has carefully planned four core exhibition areas, completely covering the entire industrial chain from HPHT/CVD core equipment, high-purity raw materials, jewelry-grade and industrial-grade finished products, to testing and certification, and intelligent manufacturing solutions. The exhibition is expected to attract 30,000+ professional visitors from more than 20 countries and regions, covering diverse groups such as jewelry brands, industrial manufacturing enterprises, scientific research institutes, and investment institutions. The concurrently held "Global Lab-Grown Diamond Industry Development Forum", "Technology Matchmaking Meeting", and "Procurement Matchmaking Meeting" will efficiently link both ends of supply and demand and facilitate substantive commercial cooperation.

IV. Resonance of Dual Tracks, Mining Two-Way Value of Consumption and Industry

Lab-grown diamonds are no longer limited to the jewelry consumption track — their excellent thermal conductivity and electron mobility make them show revolutionary application prospects in cutting-edge industrial fields such as semiconductor heat dissipation, quantum computing, and optical windows. LGD&E 2026 features a special innovative technology and application scenario experience zone to fully present the cross-border value leap of lab-grown diamonds from jewelry to new industrial materials. Exhibitors can not only connect with traditional jewelry procurement channels but also reach cooperation needs in emerging industrial ends such as semiconductors and precision manufacturing, expanding diversified business growth points.
