The Gem and Jewelry Institute of Thailand
Enrol on GIT's on-site or online training courses, or attend one of the seminars and workshops it runs alongside its gem testing laboratory and gemmological instrument services.
The visit
Why it is worth the trip
GIT is Thailand's national gem institute and runs the laboratory much of the local trade tests against, so its teaching reflects how stones are actually assessed there.
