Understanding the Basics

As you peruse the chart, you may want to refresh your mind regarding diamond basics. Called the "four Cs," understanding these terms is important if you are purchasing a high quality diamond:

  • Color - The color of a diamond has a dramatic effect on its value and quality. Colorless gems fetch the highest per-carat price.
  • Clarity - The clarity of a diamond refers to the number and size of the flaws within the gem. Flawless and near-flawless stones are the highest quality you can purchase.
  • Cut - Cutting diamonds is an art, and it needs to be done with precision and an eye for best showing off the beauty of the gem. Diamonds with a high quality cut have exceptional sparkle.
  • Carat - Carat refers to the weight of a diamond and does not have any influence on the quality of the gem. However, you'll pay less for a high quality diamond if it is smaller and has a lower carat weight.

Know What's Important to You

If you're shopping for a diamond, it's easy to get caught up in buying the highest quality stone you can afford. However, the style and metal color of the setting can make some of these characteristics more important than others. Know which aspects of diamond quality are most important to you, so you can choose the diamond that best fits your own needs.
