Why Diamond is so shiny?
As the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction. This refraction and dispersion also creates natural light and dark areas in the refracted light, depending on where the light hits along the planes of the diamond.
