The Diamond Quality Pyramid is a way to compare diamonds. While all diamonds are precious, those closest to the top of the pyramid, possessing the best combination of cut, clarity, carat weight and color are the earth’s rarest, most valuable and most beautiful to the eye.

The 4Cs

To establish a diamond’s quality, jewelers examine each of the 4Cs – cut, clarity, carat weight and color. The combination of the 4Cs determines the value of a particular diamond. For example, a colorless diamond is at the top of the Diamond Quality Pyramid in color, but if it lacks clarity, is small or not well cut, it will have a lower value. The finest stones are at the top of the Pyramid in each of the 4Cs, and are the most valuable.

When you choose a diamond, knowing it’s place in the Diamond Quality Pyramid will help you to make an informed decision. Ultimately, you’ll discover the unique combination of the 4Cs that makes a diamond right for you. The right diamond will reflect your feelings and make any occasion shine.
