The past conferences have not only served as academic platforms but also as networking forums for peers, academia, and industry experts. From the series of GIT Conferences, we are sure that many of you have already become acquainted with each other, although some are meeting for the first time. This is a chance to reconnect with old friends and make new ones, as well as for all of us to continue building a strong network for future cooperation.

This event will elevate Thailand progress toward becoming a global leader in the sustainable gem and jewelry industry.
