Beyond 4C's

The 4 Cs—Cut, Color, Clarity, and Carat weight—are the basic factors used to judge a diamond’s quality. But there's more to a diamond than just these four features. Some hidden details can also affect how a diamond looks and how much it's worth.

Fluorescence – How a diamond reacts to UV light. In some diamonds, strong fluorescence can make the stone appear cloudy, while in others, especially lower color grades, it can enhance whiteness.

Diamond treatments – Techniques like laser drilling or fracture filling improve appearance but may affect value and durability. Always ask if a diamond has been treated.

Symmetry and optical precision – Perfectly aligned facets reflect more light, giving the diamond better brilliance.

Proportions, crown and pavilion angles, and girdle thickness – These affect how well the diamond reflects light and how durable it is. Poor proportions can reduce sparkle—even in high-grade diamonds.

Growth lines and internal graining – Can cause a hazy look, even if the clarity grade is high. Always view a diamond in different lighting to judge its real beauty.
