In fact, buying a smaller diamond in a better cut makes more sense than buying a larger diamond of an inferior cut. Here’s why:

The cut of your diamond is definitely one of its most important features. Choose a reputable jeweler who can help you find the perfect combination of all the “c’s” in your diamond.
