Zusammenfassung:	METHOD FOR ASSESSING DIAMOND QUALITY A method for assessing diamonds of differing quality characteristics in which a laser Raman spectrometer is initially calibrated by use of diamonds of known quality characteristics, the characteristics having been assessed for example by a conventional subjective procedure. Diamonds of unknown quality characteristic are successively placed in the spectrometer and irradiated with laser radiation of known frequency. The intensity of the scattered Raman signal from the diamond of unknown quality is monitored for one or more orientations of the diamond, the resultant signal being capable of relation to the quality of the diamond.
