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

The range of temperature used for HPHT treatment is discussed in detail. The influence of pressure on the process of defect transforma

The Hope for American School Reformf 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
