The labs say identification of the new CVD material is fairly straightforward, but whether or not the average retailer/gemologist can do it remains uncertain. GIA GTL reports, "Characteristic strain patterns were observed [under the microscope], which were different from those seen in natural diamonds." The lab also writes, "The CVD synthetic diamonds displayed strong red fluorescence while exposed to high-energy UV radiation in the De Beers DiamondView." The DiamondView was designed to detect synthetic diamond. Observations by EGL USA include seeing clouds of white parti
