GSI Opens New Lab in Thailand
Located in Bangkok, the laboratory is Gemological Science International’s 14th location worldwide.

The laboratory, GSI’s 14th worldwide, is located in the center of Bangkok’s gem and jewelry district.
GSI said the lab will provide comprehensive testing, analysis, and grading report services for colored gemstones, natural and lab-grown diamonds, finished jewelry, and pearls.
GSI Thailand also will offer screening for lab-grown diamonds and simulants.
The lab will be staffed by a “highly trained” team of local gemologists, GSI said.
“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,” GSI President Debbie Azar said.
“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.”
GSI was founded in 2005 and is based in New York.
