4C OF A DIAMOND
CUT
As a diamond’s brilliance is largely determined by its cut, it is the most important category of the 4Cs. Cut does not refer to a diamond’s shape but to the diamond’s proportions, symmetry and polish, so even if a diamond has perfect clarity and color, it can appear dark with a poor cut. Highly skilled craftsmanship is required in order to cut a diamond with perfect proportions so that the maximum amount of light is returned from the top of the diamond.
Grunberger Diamonds applies further expertise in order to consistently cut all melee size diamonds (every size ranging from 0.70mm ~ 3.70mm) with perfect proportions and symmetry.

CLARITY
Clarity assesses internal defects or inclusions, and surface blemishes of a diamond. As diamonds are created under high heat and pressure deep within the earth, this process organically leads to diamonds containing natural inclusions.
Diamonds with the fewer and smallest number of these characteristics receive a higher clarity grades ranging from FL, or Flawless, to I, which have a number of inclusions that is visible to the naked eye.

COLOR
Color is the second most important characteristic of a diamond after diamond cut. White or colorless diamonds exist on a scale of many different shades, ranging from the highest quality colorless white (D) to light yellow (Z).

CARAT
Carat of a diamond refers to the weight of a diamond, not necessarily its size. The carat and the cut of a diamond go hand in hand as the two categories affect each other.
For example, a diamond with a high carat and a poor cut can result to a deep cut diamond that appears smaller in size from the top, as all of the weight is at the lower half of the diamond. Meanwhile, a diamond with a smaller carat and an excellent cut can appear larger in size to the eye.
