Dr. Eduard J. Gubelin, one of the forefathers of modern gemology, and who was a Founding Organizing Member as well as an Honorary Member of the International Colored Gemstone Association (ICA), passed away in Lucerne, Switzerland in March at the age of 91. Dr. Gubelin was the grandfather of ICA Director Edward Boehm.Dr. Gubelin joined his father's - Eduard Gubelin Sr - gems ad jewellery business during the first quarter of the twentieth century and was soon directed toward gemology as his father established a state-of-the-art gemological laboratory in Lucerne. Gubelin himself became well known throughout the world for his tremendous research and work in gemology. He was the author of numerous publications, spanning many decades, including the classic Internal World of Gemstones: Documents from Space & Time (1974), which showed how the direct source of gemstones might be identified by their inclusions. Today, the Gubelin Gem Lab in Lucerne continues to be one of the best-known, prestigious gemological laboratories.
