CUT
Cut is a diamond's most important characteristic. It has the greatest overall influence on a diamond's beauty. It determines what we generally think of as sparkle.
A diamond's cut grade is an objective measure of a diamond's light performance, or, what we generally think of as sparkle. When a diamond is cut with the proper proportions, light is reflected back to the top of the diamond. If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.

EX |
Excellent: Reflects nearly all light that enters the diamond. An exquisite and rare cut. All the dimensions are perfectly maintained in the described mathematical proportions in order to get the most sparkle. |
|
VG |
Very good cut: Reflects almost the same light as an Excellent cut, with slightly broader proportions. |
|
GD |
Good cut: Reflects most light that enters. In this case , cutter might have chosen to get bigger size to make it more economical. |
|
FR |
Fair cut: Reflects lower proportion of light due to weaker proportion that cutter has chosen to get maximum size or yield . These cuts are heavily discounted in price. |
