A diamond's 4C's comprise of a diamond's Colour, Clarity, Carat weight and Cut. Colour, Clarity and Carat weight are caused by nature but Cut is controlled by the human hand. Cut is the most important C that differentiates a diamond's value vastly. Every BrilliantC® diamond is cut to an exclusive formula of proportions and angles without compromise, to form an ideal-cut diamond that achieves the apex of brilliance, fire and scintillation, visible to the naked eye. Delivers consistent flawless light performance no matter what colour, clarity and carat weight. With an ideal cut BrilliantC® diamond, with the naked eye, you will find that it looks brighter and whiter than its graded Colour grade. This is a visible result and advantage of a BrilliantC® diamond cut.
