Asian Institute of Gemological Sciences
Take gemmology training in Bangkok's gem district, from the four-month Accredited Gemologist Diploma to a two-day course in preliminary quality opinion assessment, with online courses also offered.
The visit
Why it is worth the trip
Bangkok is where a large share of the world's coloured stones are traded and treated, so training there is done against the material actually moving through the market.
Before you go
AIGS is at 919/539 Silom Road, Jewelry Trade Center, 48th floor, Bangrak. It was founded in 1978 and states that teaching is practical, using its gemstone collection and its position within the gem district.
