Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, 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 creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.
Cut
Of all the 4Cs, cut has the greatest effect on a diamond’s beauty. In determining the quality of the cut, the grader evaluates the cutter’s skill in the fashioning of the diamond; technology. The more precise the cut, the more captivating the diamond is to the eye.Color
Gem-quality diamonds occur in many hues. In the range from colorless to light yellow or light brown. Colorless diamonds are the rarest. Other natural colors (Blue, Red, Pink for example) are known as fancy – their color grading is different than from white diamonds.- See more at: http://www.americangemsociety.org/4cs-diamonds#sthash.Ggk80v5p.dpuf

Clarity
Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes. Diamonds without inclusions or blemishes are rare; however, most characteristics can only be seen with magnification.
Carat
The carat is the diamond’s physical weight measured in metric carats. One carat equals 1/5 gram and is subdivided into 100 points. Carat weight is the most objective of the 4Cs. It involves no estimates, comparisons or judgments.

to light yellow or light brown. Colorless diamonds are the rarest. Other
natural colors (Blue, Red, Pink for example) are known as fancy – their
