The experience at AIGS was perfect from all points of view. Good teachers, good teaching materials, a large collection of gemstones to practice and last but not least, a stimulating and diverse international environment. All the staff are always helpful and available to assist students in everything they need. Hope I can put into my work all that I have learned during the beautiful months spent at AIGS. What I heard is true, the AIGS is the best gemology school especially regarding color stones.

AIGS is a wonderful school with great teachers and an amazing stone collection for students to identify, grade and price. I have friends in seven countries in Africa, whom I met at AIGS, and I'm excited to see the business through their eyes. This is one of the best parts of the experience. Students come to AIGS from all over the world and their enthusiasm and diverse experiences enrich the student experience.

AIGS is a good institute with a long history and a lot of sample color stones. Location is also excellent because downstairs in JTC, we can see all kinds of stones and query for price. We can practice the theory we learnt in the morning immediately after lunch.
