Gemological Science International expands global footprint with new lab in Bangkok, Thailand
Gemological Science International (GSI), one of the largest and most technologically advanced gemological organizations in the world, proudly announces the opening of its newest laboratory in Bangkok, Thailand — the 14th in its global network
Strategic Location in Bangkok’s Gem District
Strategically located in the heart of Bangkok’s vibrant gem and jewelry district — a city widely recognized as one of the world’s most important colored gemstone trading hubs — the new GSI lab will serve both local and international clients, offering full access to GSI’s broad range of services.
Comprehensive Testing and Certification Services
The Bangkok facility provides comprehensive testing, analysis, and certification services across a wide array of product categories, including colored gemstones, natural and lab-grown diamonds, finished jewelry, and pearls. The lab also specializes in the screening and detection of undisclosed lab-grown diamonds and simulants — an area where GSI leads the industry in innovation and accuracy.
A Strategic Milestone for the Global Gemstone Industry
The launch of GSI Thailand marks a significant step forward in supporting the global colored gemstone and jewelry supply chain. The lab is equipped with state-of-the-art instrumentation and staffed by a highly trained team of local gemologists, ensuring consistent, science-based results backed by global standards of accuracy, reliability, and transparency — all while maintaining a personal approach to service.
Reinforcing Trust Through Science-Backed Services
“Our mission is to continue expanding our laboratories to serve the evolving needs of the industry while reinforcing trust through objective, science-backed gemological services,” said Debbie Azar, President of GSI. “Bangkok has long been a global epicenter for colored gemstone trading, and it’s essential for GSI to have a strong presence here — close to where our clients operate.”
Unmatched Capabilities for Large-Scale Support
“While many labs in this region focus solely on colored gemstones, GSI offers a much broader spectrum of services. From our expertise in undisclosed diamond detection and jewellery quality control, to our unmatched ability to scale — from hundreds to hundreds of thousands of pieces practically overnight — GSI is uniquely equipped to support large-scale manufacturers and global supply chains.”
