Phornthip Saksirisamphan Synthetic and Treated Gem Identification course
For sure, AIGS is one of the best schools that I have studied. The teacher gave me not only knowledge but also Gem business ideas. Lots of materials are provided for students. All staffs are friendly and supportive. I found many people from different countries. It’s a great place for students. Synthetic and traded gemstone is very important to learn.
I’m really thankful to everyone from AIGS
