What Determines a Diamond’s Value?
When it comes to diamonds, it is often said that “it’s all about the 4 C’s.” The “Four C’s” of diamonds stand for Carat, Cut, Clarity, and Color.
Together, these characteristics determine a diamond’s value. Here is a quick explanation about the 4 C’s:
The weight of a diamond is measured in carats. The higher the carat weight, the more valuable the diamond.
Cut refers to the diamond’s proportions, symmetry, and polish. A well-cut diamond will emit light evenly and have a brilliance that really catches the eye.
Clarity has to do with how many blemishes or inclusions are present on the surface of or inside the stone. A flawless diamond is very rare and pricey.
Colored diamonds are rarer than colorless diamonds and are graded on a scale from D (no hue) to Z (a yellow hued diamond). Fancy colored diamonds such as red, blue or green are extremely rare and can be worth more than colorless diamonds.
