01
Hands-on before theory
Students see, hold and grade real stones before we open a textbook. Theory explains what your eye and your instruments are showing you.
The YGIL School
Learn gemology the way it is taught in the trade
Our school was founded with a simple idea: that anyone with curiosity and discipline can learn to evaluate gemstones accurately. We bring together working gemologists, GIA-aligned curricula, and a small lab in Yangon where students can put theory into practice.
Our story
A school grounded in Yangon
Yangon has long been one of the most important cities in the world's gem trade. Mines in Mogok, Mong Hsu and beyond feed a network of dealers, cutters and retailers who rely on the city as a centre for buying, selling and learning.
YGIL was founded to make rigorous gemological training accessible in Myanmar. We partner with established international curricula so our students can earn credentials that travel with them — while keeping our teaching locally relevant.
How we teach
Three principles for every YGIL course
Every course we run is built around three ideas we refuse to compromise on.
02
Instruments of the trade
Loupes, microscopes, refractometers, polariscopes, dichroscopes and spectroscopes are part of every practical session, not optional extras.
03
Credentials that travel
Where possible we align our courses to GIA and other recognised international standards so your progress is portable across borders.
Facilities
A small lab with the right tools
Our Tamwe classroom doubles as a working gem lab. Students use the same equipment that YGIL technicians use every day to test client stones — a deliberate choice, because learning on shared, professional tools is part of the education.
What is in the room
- 10x triplet loupes and gem clips
- Binocular gem microscopes with darkfield illumination
- Refractometers with RI fluids
- Polariscopes and conoscope
- Dichroscopes and Chelsea filters
- Spectroscopes (handheld and bench)
- UV lamps (long and short wave)
- Reference stones and synthetics set
