Abstract
FTIR technique was applied to delineate spectroscopic characteristics of natural, synthetic and irradiated diamonds. All of the samples studied in this work show the absorption peaks, which are generally observed in diamond as well as the specific one related to N in diamonds. Synthetic diamond is characterized with both the peaks of 1344 and $1128 cm^{-1}$ related to HPHT synthesis and specific $1050 cm^{-1}$ peak only observed in synthetic diamond, which can be used to discriminate natural from synthetic. Type (natural blue diamond: IIb, electron beam Irradiated blue diamond: Type Ia) can be used to discriminate natural from irradiated diamond. The intensity of specific $1450 cm^{-1}$ peak observed only in irradiated diamond is related with irradiation and annealing process.
