4C for diamonds
Until the middle of the twentieth century, there was no standard by which diamonds could be judged. GIA created the first globally accepted standard for describing diamonds called Diamond 4C.
4C stands for 4 criteria: Color, Clarity, Cut and Carat weight. Gradings of the 4C’s helped to determine the value of a diamond and estimate its quality. Now customers can know exactly what they are paying for.
– Cut refers to the quality of a diamond’s angles, proportions and symmetrical facets. All these factors directly impact a diamond’s ability to sparkle, along with its overall aesthetic appearance.
– Color is graded in terms of how colorless a diamond is. The GIA grades diamonds from D to Z, with D being the most colorless ones, and Z containing noticeable brown or yellow tint.
– Clarity evaluates the lack of inclusions and blemishes.
– Carat’s grade is the last but not least criteria. Carat refers to the weight of the diamond (not how large the stone is). Each of the 4C elements make every diamond unique – and extremely beautiful.
