Abstract
Numerous spectroscopic features characteristic of HPHT-treated diamonds are discussed. Many of these features are used as indicators of HPHT treatment. In this chapter, we summarize the data on all the optical centers throughout the UV-Vis-IR spectral range, which undergo changes during HPHT treatment and which are used for recognition of treatment. Characteristic combinations of optical centers observed in spectra of HPHT-treated diamonds are discussed. It is shown that none of the great many optical centers can be used alone for the reliable identification of HPHT treatment and only detailed analysis of many optical centers can allow a conclusive decision. Optical spectroscopy is discussed as the most reliable method of recognition of HPHT-treated diamonds.
