The 4 C’s of Diamonds
The quality of a diamond is determined by the 4C’s: Cut, Color, Clarity and Carat. These four parameters for Diamond’s Quality are the main components, but only should be used as a guide. Gradings of the 4 C’s help determine the value of a diamond and indicate its quality.
Clarity
FL diamonds are Flawless
IF diamonds are Internally Flawless
VVS diamonds (1 and 2) are Very, Very Slightly Included
VS diamonds (1 and 2) are Very Slightly Included
SI diamonds (1 and 2) are Slightly Included
I diamonds (1, 2 and 3) are Imperfect
FL diamonds are Flawless
IF diamonds are Internally Flawless
VVS diamonds (1 and 2) are Very, Very Slightly Included
VS diamonds (1 and 2) are Very Slightly Included
SI diamonds (1 and 2) are Slightly Included
I diamonds (1, 2 and 3) are Imperfect
Colour
Colour refers to the natural tint inherent in white diamonds. In nature, most white diamonds have a slight tint of yellow. The closer to being “colourless” a diamond is, the rarer it is. The industry standard for grading colour is to evaluate each stone against a master set and assign a letter grade from “D” (colourless) to “Z” (light yellow).
Carat
Carat denotes the weight of a diamond, not the size. A 1 Carat Diamond equals 200 milligrams, or 0.2 grams. Smaller diamonds are often measured in carat points. There are 100 points in every carat. A 10-point diamond weighs one-tenth of a carat, or 0.02 grams. While Carat weight is an element to consider when buying a diamond, the overall appearance and brilliance should carry more importance.
Cut
The GIA grades Diamond Cut on the scale of Ideal, Excellent, Very Good, Good, Fair and Poor. The Ideal and Excellent grades, depending on Diamond Shape, signify proportions and angles cut for maximum brilliance and fire.
