What determines the price of a diamond?

Looking to purchase a diamond? There are four main factors that play into the value of your diamond. These “4 Cs” of diamond quality are the universal method to assess the quality and cost of diamonds throughout the world.

The 4Cs


Did you know that diamonds can come in a variety of colors? Every diamond is placed on a color scale ranging from absolutely colorless (D) to naturally yellow (Z). The less color (less yellow) a diamond is, the more valuable it is.
Of course, it is important to note that there are also rare and expensive diamonds that come in blue, pink and even red!


Not every diamond is perfect. Some diamonds have what are known as “inclusions” inside. These inclusions can consist of scratches, trace minerals, or other small defects that change the way that light bounces off of the diamond. A flawless diamond with no inclusions will cost more than a diamond with obvious inclusions under 10X magnification.


Diamonds are often sought after for their sparkle. Diamonds that are cut with precision and care will reflect light off of every angle and facet, leaving you with a beautiful, bright diamond. The brightness of a diamond, or the precision in which it was cut to reflect light, will play a role in the cost of the diamond. Brighter diamonds that are well-cut will be more expensive than darker diamonds that allow light to pass through.


Last, but not least, the carat weight will affect the cost of a diamond. Diamond carat weight is how much your diamond physically weighs. The larger the diamond, the more expensive it will be. Of course, remember that although a diamond’s size is the most popular cost-factor, it is not the only factor that plays a role in how much a diamond costs.
