A questão dos diamantes artificiais continua a ser um fantasma a assombrar a indústria global de diamantes e o tema será abordado durante a Baselworld, no domingo 22 de Março. A forma, cada vez mais perfeita, com que os diamantes sintéticos são produzidos, tem levado à busca de maneiras cada vez mais sofisticadas de os detectar. Pode increver-se aqui.
O comunicado do GIA (Gemological Institute of America):
CARLSBAD, Calif. – March 3, 2015 – Leading research scientists from GIA (Gemological Institute of America) and De Beers Technologies UK will speak on the topic of synthetic diamonds during GIA GemFest Basel 2015 on Sunday, March 22 at the Congress Center Basel in Switzerland. Tom Moses, executive vice president and chief laboratory and research officer for GIA, will moderate the discussion with Dr. Simon Lawson, head of technologies UK for De Beers and Dr. Wuyi Wang, director of research and development for GIA. The free event will commence at 5 p.m. (17:00) in the Montreal Auditorium, with a reception to follow.
The technology for creating synthetic diamond has improved significantly over the last decade and, as a result, gem-quality synthetic diamonds have appeared in greater quantities and received wider media exposure. Reports of synthetics being presented as natural, however, have raised concerns within the industry. GIA and De Beers have applied years of research to identifying these laboratory-grown diamonds, resulting in devices and methods that effectively distinguish them from natural diamonds – from the smallest melee to stones of significant size. GIA’s Wang and De Beers’ Lawson will speak at GemFest Basel about the latest research on synthetic diamonds and their identification, and how GIA and De Beers are working to meet the on-going challenges posed by potential non-disclosure. A question and answer session will immediately follow the moderated discussion.
Lawson has 20 years of experience with De Beers researching the growth and characterization of synthetic diamonds. He has held a key role at De Beers since 1995 in the strategy and development of the various De Beers verification instruments used to identify synthetic and treated diamonds. Prior to joining De Beers, Lawson was awarded a Royal Society Fellowship and spent four years at the National Institute for Research in Inorganic Materials in Japan. He holds a doctorate in optical spectroscopy of diamond from King’s College in London and a Bachelor of Science degree in physics.
Wang joined GIA in 2000 and has more than 20 years of expertise in diamond geochemistry and the treatments of diamond and other gem material. He holds a doctorate in geology from the University of Tsukuba in Japan and a bachelor’s degree in geology from Beijing University in China. He is widely published in gemological and geological journals, and is recognized with numerous honors including the AGS Richard T. Liddicoat Journalism Award and Dr. Edward J. Gübelin Most Valuable Article Award from Gems & Gemology.
GemFest Basel 2015 is a free event that will be held at 5 p.m. (17:00) on Sunday, March 22 at Congress Center Basel in the Montreal Auditorium. A reception will immediately follow the panel at 6 p.m. (18:00). Registration is now available
