The global gem and jewellery industry orbits around one central sun — B2B trade fairs. These platforms power sourcing, manufacturing and export deals, luxury retail planning and gemstone discovery. From sourcing elusive Burmese rubies and even larger orders of diamonds, to announcing new jewellery launches and negotiating multi-year supplier contracts, the real business of the trade is conducted at B2B. Hosted in the deserts of Tucson, in the ateliers of Vicenza and at the bustling markets of Hong Kong and Bangkok, each show serves a specific purpose to shape today’s gem ecosystem. Here’s a deeper dive into the most important, world-class B2B gem and jewellery trade shows around the world—and why they count.

Building Your Gem-Show Strategy
Before choosing a B2B event, define your purpose — sourcing, networking, or trend discovery. Consider your product focus (rough stones, fine gems, machinery), your target geography, and your buying scale — large-volume events like Hong Kong and Bangkok differ from premium showcases like Tucson and Vicenza.
