July 11, 2018

You’ve probably heard about the 4Cs of a diamond, and you may even know that it stands for Cut, Color, Clarity and Carat Weight. Let’s take a deeper look behind the 4Cs of a diamond!

Cut

Of all the 4Cs, Cut has the greatest effect on a diamond’s beauty. In determining the quality of the cut, the diamond grader evaluates the cutter’s skill in the fashioning of the diamond. The more precise the cut, the more captivating the diamond is to the eye.

Color

Color Gem-quality diamonds occur in many hues. In the range from colorless to light yellow or light brown. Colorless diamonds are the rarest. Other natural colors (blue, red, pink for example) are known as “fancy,” and their color grading is different than from white colorless diamonds.
