Posted on Mar 14, 2013 in Diamond Carat, Diamond Clarity, Diamond Color, Diamond Cut, The Diamond 4Cs,

The prospect of purchasing a diamond may seem daunting, but through GIA, an unbiased authority on diamonds, you have several handy resources to help you select the highest quality diamond. First up, an overview of the 4Cs: Color, Clarity, Cut, and Carat Weight.

GIA created the 4Cs (Color, Clarity, Cut and Carat Weight) as a universal method for establishing the quality of any diamond, anywhere in the world. The 4Cs means two very important things: diamond quality can be communicated in a universal language, and diamond-buying consumers can know exactly what they are about to purchase.

All diamond images and diagrams are for reference only and may not reflect true diamond quality grade. Images are not for color or clarity diamond grading.
