Thank you for considering AIGS and Bangkok as the venue for your gemological studies. Since our founding, AIGS has been committed to providing the finest education possible and we continue to produce some of the world's finest gemologists.

AIGS’s location within the center of Bangkok's gem district gives students a unique insight into the inner workings of the gem and jewelry industry that cannot be experienced from a classroom environment alone. The best way to learn about gemstones is though practical hands-on contact with as many samples as possible. Our vast collection of gemstones - including many that are unusual and unique - have been collected over many decades to provide our students with the necessary knowledge, skills and hands-on experience to prepare for their new careers within the industry.

The AIGS laboratory has a long-established reputation for providing timely and accurate gemstone reports for our clients, as well as serving the industry as a whole via our extensive contributions to gemological research. Being equipped with the latest advanced technology, we ensure that our gemologists are trained and up to date on the latest identification and analysis methods. The lab offers a variety of testing and certification to meet your needs, including the newly redesigned Master Gemstone Report that includes information on the rarity of the gem and the AIGS ‘Star Rating’ in the three page fold-out portfolio.

As our organization approaches our 46th year, we are proud that our educational program, research and testing services continue to operate at the highest level within the gem and jewelry industry. We invite you to visit us in Bangkok.
