Press Release: Audiences in Japan, the third-largest consumer market in the world for gems and jewelry, will have the opportunity to hear from experts at the Gemological Institute of America (GIA) during a free GemFest seminar on July 11 in Tokyo. Dino De Ghionno, GIA's laboratory manager, will discuss gem identification challenges and offer a laboratory update. Dr. Ahmadjan Abduriyim, GIA's senior research scientist, will present on identification services at GIA’s Tokyo gem identification and grading laboratory.
De Ghionno will provide an update on the Institute’s laboratory services and discuss challenges in gem identification. He will highlight stones of gemological interest submitted to the laboratory, new gem materials and treatments, as well as gemological updates. Topics will range from black opaque stones and change-of-color amber to diffusion-treated corundum.
Abduriyim, GIA’s senior manager of colored stone services in Tokyo, will discuss recently introduced colored stone services – including identification reports and origin determinations – offered at the Tokyo lab. Several new services were introduced in GIA’s laboratories in Tokyo, Hong Kong, Bangkok, Carlsbad and New York on June 30. These services include red spinel origin services, ruby and sapphire inscription services for faceted stones weighing 0.50 carats or more, the Portrait Report and the Notable Letter.
De Ghionno has more than 35 years of experience specializing in the research and identification of a wide range of gem materials, colored diamonds and related treatments. He began his career with GIA in 1978 as a colored stone and gem identification instructor, becoming manager of the program and after 14 years transitioned to the identification department of the laboratory. De Ghionno has co-authored several articles in scientific and gemological journals, including GIA’s award-winning quarterly research journal Gems & Gemology, and has lectured in the U.S., Europe and Asia.
Abduriyim received his doctorate in mineralogy from the Division of Earth and Planetary Science at Kyoto University in Japan. He has authored numerous gemological articles, including work on geographic origin determination of major gemstones and the applications of LA-ICP-MS in the gemological field, which have been published in major gemological periodicals including Gems & Gemology.
GIA’s Tokyo GemFest will be held on July 11 beginning at 5 p.m. at Aurum, Higashi Ueno 1-26-2, Taito-ku, Tokyo. Seats are limited and available on a first-come, first-served basis; doors will open at 4:30 p.m. For questions about the GemFest, contact GIA’s laboratory in Tokyo at giatokyolab-at-gia.edu or 03-5812-0316.
