The 4 C’s is the basics of determining the value of what a diamond is worth and it’s rarity.
We use the GIA scale which has now been adopted as the international standard for grading diamonds.
Below are some brief descriptions of the 4 C’s and GIA’s official chart for reference.
Color – The color of a diamond is important for the diamonds rarity. The GIA scale uses a D-Z scale to determine how colorless a diamond is with D being completely colorless and Z being a light yellow. Any diamond that is considered to have more color then a Z is considered a fancy colored diamond. These diamonds range in several colors but the most common are yellow, blue, black, and brown diamonds.
Clarity – Clarity is the cleanness of a diamond or how many blemishes it has. The GIA scale ranges from flawless to an I3 which is considered to be heavy included. Clarity plays a big role when it comes to a diamonds value, the better the clarity the more rare they are.
Cut – Cut is the only C where humans are involved and is the most important C when it comes to a diamonds beauty. The cut of a diamond determines how light goes in and out and how much brilliance a diamond has. The GIA scale grades the cut of a diamond from Excellent to poor. The best grading for the cut of a diamond is called triple X which is where all three cuts of the diamond are graded excellent
Carat – Carat is defined as the weight of a diamond, the higher the weight the rarer a diamond is. Diamonds can weigh any certain amount of carats but the higher the carat the price of a diamond drastically sky rockets. A .25 carat is not a forth of what the same diamond would be at 1 carat. A 1 carat is more valuable then a .25 carat. This is due to the rarity of bigger diamonds not being as plentiful as there smaller counter parts.
