The cut of the Diamond is probably the single most important factor of the 4 C's. By cut, we mean the proportions and dimensions of the Diamond as opposed to the shape (round, princess, cushion, etc). The reason it is the most important is that it holds the key to the diamond’s beauty. No matter what the color, clarity, shape or carat weight of a diamond- if it is well cut it will have life and sparkle. If it is poorly cut, it will not. Even the most colorless, flawless, largest Diamond will not be as beautiful if it is poorly cut. If you see a Diamond that seems too good to be true in specs and price, it most likely is poorly cut, so beware.
The precision with which a diamond is cut is the most critical factor in releasing its “fire” and “brilliance”. Since it is the only factor that humans can control, it may be the most important of the 4 C’s. During the cutting process, fifty percent of rough diamond material is usually lost. The facets, or planes, of the diamond should be placed in exact geometric relation to each other, the culet or “point” should be in the exact center of the bottom of the diamond and the diamond needs to be well polished. This symmetry is crucial for light entering the diamond to be reflected back to the eye as “fire”. Once these geometric proportions are compromised, the beauty and brilliance of the diamond are sacrificed for size. To achieve a diamond’s truly dazzling radiance, it must be cut precisely. At Colonial Jewelers, we make no compromise in this area of diamond quality.
