Visit in Tokyo

C.I.G. Director of Education Wolf Kuehn  met with Yasukazu Suwa at SUWA's new offices in Tokyo. Yasukazu is a member of the C.I.G. Advisory board and  has been involved in the study of Angolan rough diamonds. He is presently writing a book about the beauty of diamond rough and its importance before cutting. We also both share the need of more promotion for untreated gemstones.
