When shopping for a loose diamond, or diamond jewelry it is important to know how they are evaluated. There are four different characteristics to consider when comparing and evaluating diamonds: Carat Weight, Cut, Clarity, and Color, also known as the 4 C ’s. A diamond’s shape is also an important factor when choosing a diamond and we have outlined below the characteristics that determine quality for each of the shapes. Read this guide before buying a diamond, in order to make a more informed decision.

Carat:

This term refers to the weight of the diamond, and not necessarily the size, as many might assume. Learn more about Diamond Carat

Color:
