The 4Cs Overview

The 4Cs of Diamond Quality is the universal method for assessing the quality and value of any diamond, anywhere in the world based on their Cut, Colour, Clarity and Carat

Cut                                                         

                   

Cut has the greatest impact on a diamonds sparkle therefore is the most important of the 4C's                          
                                               
Colour

Colour grading is the second most important of the 4Cs due to its ability to dull its beauty. The less colour, the higher the grade. 

Carat         
               
         

The most commonly known of the 4Cs refers to the weight of the diamond, however focusing purely on this can leave you with a large yet un-charming diamond.         
            
Clarity

Clarity is the least important of the 4C's because the flaws it refers to are often unnoticeable to the naked eye.
