The diamond market has some complex challenges that include the distinction of natural and synthetic diamond and the identification of the color origin of natural diamonds. While certain basic methods can help to distinguish natural from synthetic diamond, most analytical tasks in diamond testing require advanced spectroscopy and imaging techniques. The identification of undisclosed synthetic diamonds, particularly in small sized, is currently one of the biggest problems of the diamond trade. Another major problem of the diamond market is the identification of the color origin of certain irradiation-related colored diamonds such as green and greenish blue and yellow green diamonds. This presentation gives an insight into the techniques used to test diamonds and the properties considered when testing them.
