Diamond grading Course

Diamond grading is a core study of diamond about its 4c’s, by which we can identify its price and quality

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. The criteria for diamond grading, most respected internationally,

Color

The color of a diamond refers to the relative amount of yellow, brown or gray body color that a stone possesses. The G.I.A. scale starts at “D” and goes through “Z”, with “D” being void of anybody color, and “Z” having a light yellow, brown or gray color.

Clarity

Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a stone’s clarity grade and affect its cost. Clarity is determined using 10X magnification. By definition, if something is not visible at 10X, it does not effect the clarity.

Carat Weight

Carat is a unit of weight, not size. There are 5 carats in a gram. The weight of a diamond is measured in carats.

Cut

At the turn of the last century, it was mathematically determined, what the optimal proportions for a diamond should be to assure maximum brilliance and dispersion.
