Established in Bangkok in 2017, the Institute of Gem Trading offers gemological courses based on decades of experience in mining, cutting, and gem trading. Through our modular short courses, you will learn the skills of the modern professional field gemologists such as grading rough colored gemstones, cutting and recutting gems in order to maximize values, as well as mastering the trade secrets of the colored gemstones market. With a hands-on approach, students will learn through lectures, videos, interactive demonstrations, sample specimens, workshops, field trips, and seminars by industry leaders.
The Missing Link in Gem Training
Utilizing our experience in various aspects of the gem trade, we have designed courses to teach all the needed knowledge from mine to market; how to examine gem rough, cut them into valuable and saleable gemstones, and find success in the international gemstone trade.
A Hands On Method
IGT gives its students the ability to gain practical knowledge through the use of natural gemstones. We house a world-class gemstone library for use in the classroom and we teach our students how to use gemological tools to analyze them.
Professional Network and Knowledge
Our courses reveal many previously guarded trade secrets and we teach skills that are usually unavailable outside of a family-run gemstone business or a long-term traditional apprenticeship.
The Modular Approach
Whether you would prefer to visit Bangkok for a week to expand your knowledge or immerse yourself in the full month educational training program that we offer, IGT's modular courses can accommodate your needs.
Our team and founders are passionate communicators with years of first-hand experience in the gem trade.
