It is experimentally established that the luminescence spectrum of diamond at room temperature contains one or two peaks in the form of Gauss curves. This result is related to the exciton-phonon interaction in diamond, which, along with the zero-phonon line, contains first and second order phonon repetitions. This phenomenon is typical only for natural diamonds and is absent in synthetic samples. Therefore, it can be used to identify cut diamonds (diamonds).
