Core advantages of the exhibition

1、 Anchoring the core location of global industries and enjoying a market dividend of billions of yuan

China is the undisputed production center and technological source for cultivating the diamond industry worldwide - with rough production capacity accounting for about 63% of the world's total, of which about 80% is produced in Henan. In 2026, China's cultivated diamond market officially enters a growth cycle of billions, and global production capacity and innovation potential continue to gather in China. LGD&E 2026 is based in Shanghai, an international trade hub. With a display area of 30000 square meters, it gathers global leading enterprises, research institutions, and professional buyers to help exhibitors accurately locate the fastest-growing core market in the world and share the billion dollar industrial dividend.

2、 Relying on the Shanghai International Convention and Exhibition Capitaltop-tierplatform effect

Shanghai is one of the most active cities in the world for exhibition activities, with a total exhibition area of over 19.3 million square meters, firmly ranking first among major exhibition cities in the world; The proportion of international exhibition area continues to remain above 80%, and all of the top ten global exhibition groups have settled in Shanghai. As the permanent venue of the CIIE, the National Convention and Exhibition Center (Shanghai) holds over 8 million square meters of exhibitions, conferences, and events annually, accounting for nearly 40% of the city's exhibition scale. It undertakes more than 20 large-scale professional exhibitions of 100000 square meters each year. LGD&E 2026 will be held here, fully relying on the professional operational capabilities and global influence of this mature platform, to provide exhibitors with one-stop high-level support from exhibition hardware to exhibition services.

3、 Full industry chain coverage, precise docking of diverse procurement needs

This exhibition has carefully planned four core exhibition areas, covering the entire industry chain from HPHT/CVD core equipment, high-purity raw materials, jewelry grade and industrial grade products, to testing and certification, and intelligent manufacturing solutions. The exhibition is expected to attract over 30000 professional visitors from more than 20 countries and regions, covering diverse groups such as jewelry brands, industrial manufacturing enterprises, research institutions, and investment institutions. The "Global Diamond Industry Development Forum", "Technology Matchmaking Meeting" and "Procurement Matchmaking Meeting" held at the same time will efficiently link the supply and demand sides and promote substantive commercial cooperation.
