4Cs (Cut, Color, Clarity, Carat)

The 4Cs—Cut, Color, Clarity, and Carat—are standards used to evaluate a diamond's quality. The Cut refers to how well a diamond’s facets reflect light, impacting sparkle. Color measures the absence of color; the less color, the higher the value. Clarity assesses the presence of internal flaws or blemishes, with fewer inclusions being better. Carat indicates the weight or size of the diamond. Together, these factors determine a diamond’s beauty and value, helping buyers make informed decisions.
