Proportion – Understanding Brilliance, Dispersion & Scintillation
A well-cut diamond will exhibit three main characteristics - Brilliance, Dispersion and Scintillation. When a beam of light falls on a diamond, the light will either enter the stone or reflect off. The light that gets reflected off the surface is known as a diamond’s brilliance. The light that passes through a diamond, where some of the light rays get separated into flashes of colour. The process is known as dispersion. This division of white light into its spectral colours (or the result of dispersion) is known as fire. The spectrum of colours viewed by the viewer as he/she moves the stone back and forth is known as scintillation.
