Each diamond is unique. GIA created the first, and now globally accepted standard for describing diamonds: "Colour", "Clarity", "Cut", and "Carat Weight". Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The value of a diamond is based upon 4Cs as well.
