The Gemological Institute of America (GIA) is offering a new seminar course that teaches jewellers how to differentiate synthetic diamonds from natural ones.
The one-day program, taught by GIA research scientists and experienced classroom instructors, will combine lectures with practical lab instruction, including the latest GIA instrumentation for differentiating natural diamonds from CVD and HPHT synthetic diamonds and diamond simulants.
Wuyi Wang, vice president of research and development, said: “GIA examined and characterised the earliest gem-quality synthetic diamonds nearly 50 years ago. Since then, we have continued to build the institute’s expertise in identifying synthetics through robust, published research into their properties.
He added: “This combination of decades of experience in delivering quality, relevant education and in-depth independent research into natural and synthetic diamonds is unique to GIA.
“As the public becomes more aware of gem-quality synthetic diamonds – including melee sizes – it is imperative that the industry is prepared with training and expertise to address consumer concerns.”
