Cut

Cut measures how well-proportioned a diamond’s dimensions are, including its balance and brilliance. This influences how well a diamond interacts with light, impacting its brilliance, fire and scintillation. A well-cut diamond will look its very best with optimal light performance. Diamond cut is considered the most important of the four Cs. No matter which diamond jewelry style you choose, you’ll always want to prioritize cut.

Color

Diamond color refers to how colorless a diamond is. Color is the second most important of the 4Cs of diamonds. Colorlessness is a desirable feature in most diamonds and the more colorless
diamonds are rarer. The less color a diamond has, the higher the diamond color grade. Certain jewelry metals can complement faint color diamonds, so diamond color is a flexible 4C that can vary depending on preferences and jewelry settings.

Clarity

Clarity assesses small imperfections within a diamond. Inclusions can occur naturally during the diamond forming process for both natural and lab diamonds. Clarity is used to quantify and specify any inclusions. When it comes to the four C’s of diamonds, clarity is typically not the most important, as many blemishes are too small to be seen without magnification. But some larger blemishes can be visible. Review a diamond’s clarity plot to see its inclusions.

Carat Weight

Carat measures a diamond’s weight, not its size . This 4C of diamonds dates back to the 1500s when carob seeds were used to measure diamonds and gemstones. Today, carat refers to an exact weight of 200 milligrams. Carat weight choice is a matter of preference, one weight is not necessarily better than another. Typically, heavier high-quality diamonds are rarer than ones with lower carat weights and diamond prices can reflect this.
