Geological Studies of Colored Stone Gem Deposits
Colored stone deposits occur in a wide range of environments, and these determine the types of gem materials that form and their properties. With new analytical methods providing valuable data on color-causing elements and diagnostic inclusions, country-of-origin determinations should become more accurate. These findings will also provide clues that can be used to find similar types of gem deposits.
DR. RAQUEL ALONSO-PEREZ
Dr. Raquel Alonso-Perez is curator of the Mineralogical and Geological Museum, Harvard University (MGMH). She received her PhD in Earth and Material Sciences from the Swiss Federal Institute of Technology (ETH) in Zurich and graduated as a gemologist from Gem-A. Her teaching strengths are mineralogy and gemology, and her main research interest is the study of gem deposits using non-destructive analytical techniques.
DR. LEE GROAT
Department of Earth, Ocean and Atmospheric Sciences
University of British Columbia
Dr. Groat has been a faculty member at the University of British Columbia, Department of Earth, Ocean and Atmospheric Sciences, since 1989, was the editor of American Mineralogist, and is the editor of The Canadian Mineralogist. His main research interests are the geology of gem deposits, pegmatites, the crystal chemistry of minerals and economic geology. Dr. Groat is also an independent director of multiple companies in the exploration and technology spheres.
Head Of Development
Gübelin Gem Lab
Klemens Link oversees the development of the Gübelin Gem Lab, where he is closely involved in establishing the Provenance Proof Blockchain initiative and developing the emerald paternity test. Mr. Link studied geology at Giessen University in Germany. From 2006 to 2013, he worked as a petrologist and research scientist at Johannes Gutenberg University in Mainz. Mr. Link joined the Gübelin Gem Lab in 2013 as research analyst and geochemical specialist and has helped conduct research on the age determination of sapphires.
Museum of Natural History - Luxembourg
Peter Lyckberg is a lifelong mineral collector and researcher from Sweden. He travels the world to study the geology and mineralogy of gem and ore deposits in situ. He has extensive knowledge of the suite of gem pegmatite fields in countries such as Norway, Sweden, Finland, Ukraine, Russia, Afghanistan, Pakistan, Namibia, Brazil, and the United States. A well-known speaker, Dr. Lyckberg works as a nuclear inspector for the European Commission in Luxembourg.
