There’s More to a Diamond Than Meets the Eye

There’s no doubt that diamonds are an object of fancy and a woman’s best friend. While an experienced buyer will understand how diamonds are categorized and what makes them unique, a novice may appear completely lost. Fortunately, if you’re looking to gain an in-depth understanding of diamonds, the team at Voski Jewelers has put together some useful information that we believe will guide you while making a purchase.

Diamond Cut

The cut of a diamond refers not to its shape, but the balance of proportion, symmetry, and polish achieved by the diamond cutter. The extent of how well the diamond is cut is directly related to the diamond’s overall beauty. When a diamond has been correctly cut, the diamond’s ability to reflect and refract light is greatly enhanced. By understanding the way that light moves through diamond crystals, modern diamond cutters have established a specific set of proportions and angles that are known to harness the diamond’s internal brilliance and to show it in its best light.

Cut is considered to be the most important of all of the diamond characteristics, as a well-cut diamond will often appear larger than a poorly cut diamond of the same carat weight, and have the appearance of enhanced color and clarity.

Reflections Make a Diamond's Cut Grade

The best cut diamonds have proportions that are within tried and true ranges known for maximizing brilliance, fire, and scintillation.

Brilliance

Brilliance, or brightness, refers to the white light that is reflected back to the eye from the diamond. Light enters through the top of the diamond - the table is broken down into a rainbow of spectral colors and is reflected back and forth in the interior of the gem by bouncing off the mirror-like facets. Light exits through the table, recombining as white light.

Dispersion (Fire)

Dispersion is the rainbow of colors that is reflected back to the eye from the diamond. Light enters through the top of the diamond, is broken down into a rainbow of spectral colors, and is reflected back and forth in the interior of the gem by bouncing off the mirror-like facets. When it leaves through the crown, it stays separated and reaches the eye in flashes of color.

Scintillation

Scintillation is the play of light you see with movement of the diamond, demonstrated by sparkling on the diamond’s surface. A diamond is evaluated on its ability to reflect and refract light in all directions.
Diamond Characteristics

The top portion of the diamond, from the girdle to the table.

The lower portion of a diamond, from the girdle to the culet.

The facet or point on the bottom of the diamond’s pavilion.

The narrow rim around the widest part of a diamond, separating the crown from the pavilion. Also referred to as the setting edge, where a diamond is held when set in jewelry.

The height of a gemstone, from the culet to the table. Determined as a percentage of the overall diameter of the gem.

The Cut Grading Scale

Several proportion factors have the most immediate impact on a diamond’s ability to reflect light correctly. A well-cut diamond is proportioned so that most of the light entering the gem exits back through the top of the stone, perfectly balancing the white light (brilliance) with intense flashes of fire (dispersion). A poorly cut diamond, with facets cut only a few degrees out of alignment, can result in light exiting through the bottom of the diamond, known as light leakage, instead of from the top where it is visible. This creates a diamond with dulled brilliance from poor light performance within the gem, making the center of the gem look dark.
