Say “suit of diamonds” to a jeweler, and the jeweler is likely to say “those are no diamonds.” Experts know that a four sided diamond isn’t going to radiate light like the diamond used in jewelry. However, the exact number of facets in a diamond is the key to its appearance. Each facet reflects light and makes those little sparkles and hints of color that are so mesmerizing.
But, we should note that this is one of those things where more isn’t necessarily more. Like windows and mirrors where one lets the light in and the other bounces light out. Like a prism, white light gets shattered into individual colors. When windows and mirrors are angled just right, white light bounces in a specific direction. In the jewelry industry, we call that phenomenon "scintillation."
