AIGS — the Asian Institute of Gemological Sciences — is a Bangkok-based gemmology school and laboratory whose students study in the middle of one of the world\'s great coloured-stone trading districts. Its teaching asset is a large gemstone collection for identification and grading practice, and its reputation — by its own students\' accounts — stands particularly on coloured stones.
Much of the coloured stone jewellery sold in Singapore passes through Bangkok at some point, so Bangkok institutions sit close to the source of the trade. For learning, the honest comparison is location and mode: studying in Bangkok immerses you in the Thai trade; studying at JDMIS in Singapore trains the same identification skills — refractometer, specific gravity, microscope, treatments — against the stones and markets you will actually work with here, with GT100 and GT200 progression and no relocation. Some professionals do both. Our free Gem Globe and corundum guide show why the region\'s gem geography matters.
Where is AIGS located?
AIGS is based in central Bangkok, Thailand — in the heart of Bangkok's gem district, with laboratory and education operations.
Is AIGS a good option for Singaporeans learning gemmology?
AIGS offers immersion in Bangkok's coloured-stone trade. Singapore-based learners can get equivalent hands-on identification training locally at JDMIS (GT100/GT200) without relocating — some professionals do both.
Laboratories verify; gemmologists understand. JDMIS teaches the trade's gem knowledge in two steps — no science background needed:
