The 4Cs of Diamonds

Learn about the 4Cs of diamonds - Cut, Color, Clarity, and Carat - and how they define the brilliance and beauty of engagement rings. Diamonds are evaluated by Cut, Color, Clarity, and Carat weight, the internationally recognized standard for diamond quality.

Cut

Refers to a diamond’s symmetry, proportion, and polish. A well cut diamond maximizes brilliance, light dispersion, and scintillation, creating dazzling sparkle.

Color

Diamonds are graded from D, which is colorless, to Z, which shows noticeable color. Less color is rarer and offers subtle elegance and refined beauty.

Clarity

Measures internal and surface imperfections. Fewer inclusions mean higher clarity, but each diamond’s natural characteristics make it unique.

Carat Weight

Represents the diamond’s actual weight, not its size, influencing its presence and proportion in a ring.
