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 man can control, it may very well be the most important of the four Cs in determining the beauty and value of a diamond.

During the cutting process, 50 percent of the rough diamond material is usually lost. An exact mathematical formula is used to align the facets, which are small polished planes. All the facets should be in exact geometric relation to each other. One side of the diamond should match the other and the point, or "culet", should be in the exact center of the diamond. And then the diamond should be well-polished. In order to maximize brilliance, the diamond cutter must proportion the diamond to precise dimensions. Once these proportions go beyond the ideal, the diamond is considered to be "spread", or compromised. Beauty and brilliance are sacrificed for size.

This symmetry plays a crucial role in the degree of brilliance, or light, reflected back to the eye. When this reflected light ray emerges from the top of the diamond and is refracted, or bent, it separates into the colors of the spectrum and is called "dispersion" or "fire".


We make no compromise in this critical area of diamond quality.

1. When a diamond is cut to good proportions, light is reflected from one facet to another and then disperses through the top of the stone.

2. If the cut of the diamond is too deep, some light escapes through the opposite side of the pavilion.

3. If the cut is too shallow, light escapes through the pavilion before it can be reflected.
