What Are The Four C's?

Diamonds are one of the most coveted gems. To determine a diamond's value experts use the Four C's - Cut, Color, Clarity, and Carat Weight. But lets not forget, cut, color and clarity depend on the quality of the rough diamond.



A diamond’s overall proportions, as well as the size and position of its facets, make up the cut. The consistency and balance of these can greatly affect how the stone captures light and reflects it back to the eye.



A diamond’s clarity is measured by the existence or absence of visible flaws. Tiny surface blemishes or internal inclusions, even those seen only under magnification, can alter the brilliance of the diamond and thus affect its value.



One factor that determines the value of a diamond is its color. With the exception of fancy-colored diamonds, the most valuable diamonds are those with the least color. Although many people think of gem-quality diamonds as colorless, completely colorless diamonds are very rare.

Each letter grade represents a range of color.



Carat refers to the diamond’s weight. You may also hear the weight of a diamond referred to in points. One carat is equivalent to 100 points, so a 75-point diamond is equal to 0.75 carats. Because they are rarer, larger diamonds have greater value per carat. Therefore, the price of a diamond rises exponentially in regards to its size.


All gem quality diamonds take billions of years for nature to form them, making them rare. The four C's can help inform you to identify the quality of the diamond you are purchasing, it is the combination of these four characteristics (cut, clarity, color, carat) which determine a diamonds rarity and value.
