Scientists have devised various methods to calculate the same so that they can regulate the fire and thereby have greater control over the brilliance of diamonds. Below is the computer simulation method used by the GIA to calculate the brilliance of a diamond. This can be beneficial if you were putting up a 1-carat diamond ring sale.
How the GIA Grades a Stone
The GIA uses a computer that runs a simulation of a three-dimensional structure of a flawless, brilliant, and colorless diamond with fifty-eight facets. The diamond is completely symmetric as well as polished to perfection. Further, they introduce eight-cut parameters that are pivotal in determining the interaction between the diamond and light.
The GIA conducted several computer simulations to study the brilliance and the individual factors responsible for the stone’s sparkle. It revealed that the type of cut, as well as physical attributes, could modify the brilliance of a diamond. The study even found that the American ideal cut produced some of the least brilliant diamonds. Besides, it refuted the common belief that the cut of the diamond was the sole determinant of the brilliance of a diamond.
