Tay Thye Sun is a Singapore gemologist and the founder of Far East Gemological Lab and Far East Gemological Institute. Tay Thye Sun has been practicing gemology after he graduated from the Gemological Institute of America since 1980. Before he went full-time on gem testing lab work and instructor, he was an experienced gem dealer and doing wholesale and retail jewellery business. In 1985, he came across some of the natural rubies with very little inclusions and very difficult to authenticate the nature of the rubies. This prompted him to find out more and in doing so had slowly drawn him into the world of gem research. To date, he and his many co-authors have published many articles in gemological journals around the world. One of his notable works is determining a 2,600-kg green statue to see whether it is jade. He collaborated with the National University of Singapore and Singapore Polytechnic and found out that the piece was green feldspar, not jade.〔The Straits Times, 16 July 2005 (Saturday)〕 He was invited to speak in APEC Melbourne 2000, APEC Beijing 2000, 60th Anniversary of the German Gemmological Association 1992, Germany; and the prestigious meeting by invitation only of the International Gemmological Conference held in Spain 2001, India 1999, Germany 1997, Thailand 1995, etc. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tay Thye Sun」の詳細全文を読む スポンサード リンク
