Diamond Brilliance
Theories, Measurements and Judgements
ABSTRACT: The observation of brilliance in a diamond involves a complex interaction of the viewer, the illumination environment, and the manner in which light is processed by a diamond. In order to measure the brilliance of a diamond, a computer simulation of this interaction must model all three of these aspects. The success of any theoretical measure of brilliance is how well it agrees with human judgment. Press Here to read entire Article
