FIELD: technology for processing diamonds into brilliants.
SUBSTANCE: in the method, by experimental or calculation-theoretic way in glow images visible to observer optical characteristics of diamond glow are determined, including glow intensiveness, glow glimmer and color saturation of glow, characterized by level of decomposition of white color on rainbow colors, and also relief coefficient of glow, characterized by average number of intensive color spots in glow image, distinctive to human eye, and additionally, by dividing glow image on compound portions, average values of glow intensiveness of compound portions are measured. Optical characteristics of glow are transformed to glow factors. As average coefficient of brilliant glow charm, which is used to estimate brilliant glow charm, charm coefficient is used, calculated as average value of factors of intensiveness, glimmering, color saturation and glow image geometry.
EFFECT: possible objective measurement and numeric estimation of brilliants glow charm, and possible certification of them on basis of glow charm.
