Visit GIA at International Jewellery Kobe (IJK). Connect with representatives from the laboratory on available services. Learn about our current Japanese-language eLearning course and lab class education offerings at GIA in Tokyo, as well as new courses available late 2019. The additional courses will enable students to earn the GIA Graduate Diamonds and Applied Jewelry Professional diplomas. See a demo of the GIA iD100, a sophisticated and easy-to-operate desktop instrument that distinguishes natural diamonds from laboratory-grown (HPHT and CVD) diamonds and diamond simulants.
