The effect of some color centers on the coloration of natural and synthetic diamonds

Yu. A. Klyuev, A. M. Naletov

Abstract

Mechanisms of the formation of diamond coloration caused by the light absorption by basic impurity defects, which are optically active in the visible region, have been studied. The analytical relationships between the relative concentration of each defect and the diamond main color tone and saturation have been derived. The influence of the centers under study on the diamond coloration has been compared.
