Affiliated Organisations
Gemmological Society of Japan

 

The Gemmological Society of Japan – GSJ, was initiated in 1974, with the aim to improve the level of gemmological activity, promote research activity in gemmology, and build a bridge between academic and gem testing fields. The initiation of the Society was based on a strong desire of gemmologists working in gem testing laboratories, who felt the need to develop a common, non-commercial forum to present and discuss their experiences and achievements. 
 
GAAJ-ZENHOKYO lectures regularly in GSJ’s annual meetings and our professional abstracts appear in GSJ’s journal.
