Martina Barcelloni Corte,Paola Viganò. 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 di

Since all natural diamonds fluoresce under UV excitation, the visual luminescence technique is a common method applicable to diamonds of all types. The change of luminescence color after HPHT treatment and the formation of characterist

Diamonds Used for HPHT Treatment,. Low clarity diamonds with many inclusions may considerably stimulate internal graphitization and development of cracks during HPHT annealing making HPHT treatment useless. Diamond type is a technological rather than commercial parameter of diamond. It is a key factor for determination the HPHT tre

HPHT-Induced Transformations,f the processes of nitrogen defect aggregation and dissociation is given. Stimulating action of vacancies and nickel in the nitrogen-defect transformation processes is discussed. It is shown that the understanding of the nitrogen defect transformation processes is a key to recognition of HPHT-treate
