The 4 Cs of diamonds are cut, color, clarity and carat weight. These factors are all originally determined by nature and contribute to the rarity and value of a diamond. Cut, color and clarity are three factors that diamonds are graded on; however, at Hearts On Fire, we focus on the cut of the diamond above all else. Cut is the only attribute of a diamond that man controls and contributes more to the beauty (sparkle) and value of a diamond than any of the other Cs. The industry actually states that cut can affect the value of a diamond by as much as 50% or more, even if the other three attributes remain consistent.
