TO TRULY UNDER YOUR DIAMOND’S VISUAL BEAUTY, YOU NEED TO UNDERSTAND ITS LIGHT PERFORMANCE.
Beyond the “4Cs" of diamond education, (Carat, Cut, Colour & Clarity,) Light Performance adds a new dimension to diamond grading.
It provides a rich, comprehensive and objective view of a diamond’s beauty.
Light performance is the measure of your diamond’s interaction with light. It is the most accurate and comprehensive way to determine a diamond’s visual beauty and appeal.
No two diamonds have the same light return, so the light performance grade reflects the diamond’s unique story.
