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