The 4 Cs Explained by a Private Jeweler

The 4 Cs—cut, color, clarity, and carat— define diamond quality. But at Lauren O Jewels, we help you look beyond the numbers to see how each “C” contributes to beauty, balance, and value.

Cut: Light and Life

Cut is the heart of a diamond’s sparkle. Perfect proportions, symmetry, and polish determine how light moves through the stone. In your private consultation, we demonstrate why cut quality often outweighs carat size—and how to recognize it firsthand.

Color: Mood and Metal

Diamond color ranges from icy white to warm tones that glow against yellow or rose gold. We compare stones under grading lamps so you can see the subtle differences for yourself, helping you find the tone that complements your setting and skin.

Clarity: Character and Value

We examine each diamond under magnification, showing how inclusions impact both appearance and strength. You’ll learn why an “eye-clean” diamond can look identical to higher grades—and represent exceptional value.

Carat: Scale and Proportion

Carat measures weight, not visible size. Two stones of the same carat can look different depending on depth and table spread. Through our Custom Engagement Rings process, you’ll see how shape and setting can enhance perceived size without inflating budget.

Understanding the 4 Cs in context makes all the difference. Learn more about our in-person diamond sourcing consultations, or explore color alternatives through Custom Sapphire Sourcing — where every stone is evaluated for hue, brilliance, and origin.
