To estabish 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 scale in color but if it lacks clarity or is not well cut, it will be of lower value. The finest stones possess the rarest quality in each of the 4Cs, and are the most valuable.
Strive for a stone that offers the best combination of the 4Cs. Knowing a diamond's quality will help you to make an informed decision. Ultimately, you'll discover the unique combination of the 4Cs that makes a particular diamond the right choice for you. Its beauty and brilliance will capture the true sentiment of the occasion.
