The seminar will also highlight stones of gemological interest, new gem materials and treatments, as well as gemological updates. Topics will range from black opaque stones and change-of-colour amber to diffusion-treated corundum.

Several new services were introduced in GIA’s laboratories in Tokyo, Hong Kong, Bangkok, Carlsbad and New York on June 30; including red spinel origin services and ruby and sapphire inscription services for faceted stones weighing 0.50cts or more.

GIA’s Tokyo GemFest will be held on July 11 beginning at 5.00 pm at Aurum, Higashi Ueno 1-26-2, Taito-ku, Tokyo. Seats are limited and on a first-come, first-served basis.
