AB - Recently, Hanmi Gemological Institute & Laboratory (HGI) had an opportunity to examine 5 transparent syntheticmoissanite. The round brilliants ranged from 0.93 to 0.96 ct and had a colorless, pink, yellow, blue, and red color. Advancedtesting results, including Fourier-transform infrared (FTIR) and Raman spectroscopy, identified all the specimens as syntheticmoissanite. Under the microscope, all samples except the colorless were confirmed to be a synthetic moissanite coated witha colored film. EDXRF chemical analysis detected very weak X-ray fluorescence peak characteristics of Ca, Ti, and Co inthe colored samples. These features were not detected in the colorless sample. Raman spectroscopy investigation was unableto detect the 1332 cm-1(produced by sp3bonding of carbon atoms) or the ~1550 cm-1(produced by graphite-related sp2bonding) peak in the colorless sample. The SEM image of the colorless sample showed no indication of a coating. TheTEM image of the colorless sample revealed the presence of a 3~8 nm thick layer on the moissanite. Moreover, from thecorresponding STEM Z-contrast image combined with the energy-dispersive X-ray spectroscopy (EDX) line profiles andEDX elemental maps, this layer was estimated to be carbon, silicon and oxygen.
