Take a Closer Look at the 4Cs
Carat
Carat measures weight rather than size, so two stones of the same carat weight can look different depending on the shape and cut.
Diamond Color
Less color means a higher grade. The metal you choose can influence how it looks.
Diamond Clarity
Clarity refers to the tiny marks in and on a diamond. The fewer you can see, the higher the grade.
Diamond Cut
Cut controls how a diamond catches and returns light, which makes it the biggest factor in sparkle.

No. Diamonds are evaluated across the 4 Cs rather than given one overall grade, so the best combination depends on your preferences and budget.
Start with your budget, then look at how each diamond balances the 4 Cs instead of focusing on one grade alone. A KAY jewelry expert can walk you through the grading report and explain what sets each option apart.
