AGS's grading system considers 11 combinations of three parameters namely proportion, light performance, and finishing properties to evaluate the fire and brilliance of the diamond under consideration. Based on these evaluations, the grade ratings of "Ideal", "Excellent", "Very Good", "Good", "Fair" and "Poor" are assigned. A diamond that meets AGS's perfect standards of symmetry, polish and proportion for cut grade is termed as "Ideal", and it is also popularly known as a "Triple-Zero" grade.
Brightness: Here, the refractive index of both the stones play a crucial role. Refractive index is defined as the ratio of the velocity of light in a vacuum, to that in a medium. In the case of dispersion by gemstones, the refractive index is simply the measure of the degree by which a beam of light bends, when it traverses between two mediums of different optical densities. For example, a beam of light when traveling between air and CZ would bend by a degree, different from the degree while traveling between air and real diamond. So, the refractive index of diamond (2.417), being higher than that of CZ (2.176), diamond presents brighter appearance than cubic zirconia.
Chocolate diamond rings are available in all the possible designs and patterns a woman can ever imagine!

Though the glow of a gemstone may seem heavenly, there is solid science behind the phenomenon. It is the result of refraction of light. When light travels through a gemstone, its internal structure and composition causes the light waves to bend at angles. This causes it to glitter and shine.
