GTAS describes itself as "a voice for Singapore\'s gemstone industry", bringing together businesses and professionals involved in the trade, with member directory, industry news and a stated focus on collaboration, education and international engagement. Its news pages track regulatory developments affecting the trade — including coverage of the 2023 money-laundering investigation that expanded to precious stone and metal traders, the episode behind today\'s stricter compliance expectations for Singapore dealers (the same context that produced AML/CFT obligations for precious-stones businesses).
Trade associations, testing laboratories and teaching schools are the three pillars of a gem trade city. GTAS connects the traders; the laboratories profiled in this guide test the stones; and schools — JDMIS among them — train the people. Singapore\'s gemmology education landscape, from Gem-A pathways to skills-based programmes, is mapped in the full guide.

GTAS, established in 2020, is the industry association for businesses and professionals in Singapore's gemstone trade, running a member directory, industry news and education-focused activities.
Does GTAS certify gemstones?
No — GTAS is a trade association, not a testing laboratory. Gemstone certification in Singapore is done by the laboratories profiled in the JDMIS Singapore gem labs guide.
Laboratories verify; gemmologists understand. JDMIS teaches the trade's gem knowledge in two steps — no science background needed:
