Before GIA universalized the D-to-Z Color Grading Scale, a variety of other systems were used loosely, from A, B, and C , to Arabic (0, 1, 2, 3) and Roman

GIA created the 4Cs (Color, Clarity, Cut and Carat Weight) as a universal method for establishing the quality of any diamond, anywhere in the world. The 4Cs means two very important things: diamond quality can be communicated in a universal language, and diamond-buying consumers can know exactly what they are about to purchase. Diamond Grading: The 4 C's. The 4 C's, when referring to diamond value, are color, clarity, carat weight and cut. All four factors are equally important in determining the final cost of a diamond.

Each system had different approach in terms of usage of grading scale, like - Roman (I, II, III onwards), numeric (1, 2 and 3 onwards) or alphabets (A, B and C). Among all these systems, GIA grading system is the most popular and widely used. GIA International Diamond Grading System was developed in around 1950's. In this system, diamonds are Fortunately, during the middle of the twentieth century GIA (Gemological Institute of America) developed an official diamond grading system called the 4Cs of Diamond Quality: Colour, Clarity, Cut and Carat Weight. Today, the 4Cs are used globally to establish the value of each unique diamond. DIAMOND GRADING CHART Every diamond certified by the GIA undergoes a thorough, independent evaluation.

DIAMOND GRADING CHART. Every diamond certified by the GIA undergoes a thorough, independent evaluation.

Each of the four C's (Carat Weight, Cut, Color, Clarity) is accompanied by a diamond chart illustrating the differences between grades.

Diamond professionals use the grading system developed by GIA in the 1950s, which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight. Diamonds can be fashioned into a variety of shapes and still be beautiful. These are known as the 4Cs. Like the color scale, GIA’s clarity grading system developed because jewelers were using terms that could be misinterpreted, “loupe clean” or “piqué.” Today, even if you buy a diamond somewhere else in the world, the jeweler will most likely use terms like VVS 1 or SI 2 to indicate the clarity of a diamond, even if his or her Diamond grading is a complex process, part science and part art. The contemporary diamond grading system is a standardized, global way for jewelers, laboratories, and consumers to establish the characteristics of a given diamond.

The exclusive grading system, the branded diamonds, and the prestigious title that an Argyle stone carries is all the ingenious doing of the Argyle Company. The natural build of an Argyle pink diamond versus another pink diamond can include a unique bubble gum pink hue, an unusual hardness, and even a unique fluorescent blue coloring when held under an ultra violet light.

In 1953, GIA formally created its diamond grading system, known as the 4 C’s. The 4 Cs of diamond quality are the universally recognized diamond grading system still in use today. In 1955, GIA presented its first diamond grading reports, which became the hallmark of grading reports in the diamond industry.

Natural diamonds having less color are rarer; therefore, they may cost more. When writing the grades of a diamond using the AGS Scale, diamond Cut grade is first, then diamond Color, Clarity, then Carat Weight—in that order. A Diamond Grading Report details the particular characteristics of a diamond (Cut, Clarity, Carat, Color). These reports are provided by the Gemological Institute of America (GIA), one of the most well-known institutions in the diamond industry, as well as by others (AGS, EGL, or IGI).
