Services and programmes
Certification
Gem and jewelry testing
Issues internationally recognised gem-grading certificates for diamonds, rubies, sapphires, emeralds, and coloured stones. Thai ruby and sapphire certificates from GIT are accepted by US, EU, and Middle East buyers — critical for the USD 12B jewelry export sector.
Education
Gemology training
Offers diploma and certificate programmes in gemology, jewelry design, and appraisal. GIT-certified graduates work in export houses, trading firms, and customs appraisal. Chanthaburi campus serves the coloured-stone cutting cluster specifically.
Research
Gem research and standards
Develops Thai national standards for gem quality, treatment disclosure, and origin determination. Research on heat-treatment detection, synthetic identification, and country-of-origin fingerprinting supports export-quality assurance.
Promotion
Industry coordination with TGJTA
Partners with Thai Gem and Jewelry Traders Association on Bangkok Gems and Jewelry Fair — the world's third-largest gem fair. GIT provides technical support, exhibitor certification, and buyer-education programmes at the biannual event.

Standards
EUDR and origin traceability
EU regulatory pressure on conflict minerals and origin traceability elevates demand for GIT-grade certification with documented country-of-origin testing. Thai exporters increasingly require certificates for EU market access.
Competition
Lab-grown diamond substitution
Lab-grown diamonds and synthetic coloured stones are disrupting the natural-gem segment. GIT research on synthetic detection and mandatory disclosure labelling defines Thai industry standards in this transition.
Fair
Bangkok Gems and Jewelry Fair
Biannual Bangkok fair (February and September) generates ~USD 800M in orders. GIT certification quality directly influences international buyer confidence and willingness to commit orders at fair pricing.
