Chanthaburi Colored-Gemstone Trade Cluster Share
~70–80% of global ruby/sapphire flow
The Chanthaburi-Trat gem corridor in eastern Thailand is the world's dominant trading and cutting hub for rubies and sapphires sourced from Myanmar, Mozambique, Madagascar, and Sri Lanka. Industry estimates — cited by TGJTA and GIA research — place Thailand's share of global colored-gemstone trade at 70–80% by volume. The cluster's competitive moat rests on generational gem-trading expertise, a deep pool of heat-treatment artisans, and proximity to Bangkok's auction infrastructure. Government investment promotion under BOI Category 7.1 (gem and jewelry manufacturing) provides import-duty waivers on rough stones and CIT reductions for qualifying exporters, reinforcing Chanthaburi's cost advantage over competing hubs in Jaipur and Hong Kong.
