The better cut a diamond, the more brilliant.
A well cut or faceted diamond, regardless of its shape, scintillates with fire and light - offering the greatest brilliance and value.
While nature determines a diamond's clarity, carat weight and color, the hand of a master craftsman is necessary to release its fire, sparkle and beauty. When a diamond is cut to good proportions, light will reflect from one mirror-like facet to another and disperse through the top of the stone, resulting in a display of brilliance and fire.
