When it comes to buying a diamond, the first thing you should consider is the "4 Cs." The "Four Cs" of diamonds stand for Carat, Cut, Clarity, and Color. Here are more details on each: Carat weight is how a diamond is measured and is the size of the diamond. Cut is how well the diamond has been cut and includes the height, depth, angles, and other factors. It affects the diamond's symmetry, brightness, fire, and how sparkly the diamond appears. Clarity is how many blemishes or inclusions and is judged on a 6 point scale from included to flawless. Color is judged on a scale from D (no hue) to Z (a yellow hued diamond). Keep in mind that these are only guidelines and that each individual diamond is unique. When shopping for a diamond, it is important to find a reputable dealer that you can trust.
