Diamond Cut

According to gemologists, cut is the main aspect of a diamond. A cut of a diamond forms it’s facets, brings evenness and verifies the brilliance of a diamond. A well cut diamond allows light to penetrate and pass through it thereby reflecting much light and making it more sparkling.The more the cut is brilliant the more luminous is the diamond.The beauty of a diamond is solely dependent on the cut. In order to understand the cut of a diamond, first the concept of brilliance, fire and scintillation should be clear.

What is Brilliance, Fire and Scintillation?
Brilliance, fire and scintillation are the sole attributes of the cut of a diamond that contributes to its fiery sparkle. The primary factors makes a vast difference altogether in a diamond.

Brilliance - The brilliance factor affects the brightness of the diamond. The white light that enters into the diamond and reflects or bounces back from the outer surface of the diamond is called the brilliance.

Fire - The vibrant spectral color of a diamond when exposed to light is the fire factor of a diamond. When the white light reflects back from the inner surface of the diamond towards the center of the diamond the fire factor (rainbow color) settles on the top surface of the diamond.

Scintillation - The flashes of light which occurs when a diamond is moved or tilted sideways. When light passes through the diamond and reflects from the inner surface towards the center, the light which bounces back is scintillation.

 

According to G.I.A. Grading scale, cut of a diamond is categorized under Excellent, Very Good, Good, Fair & Poor. 

Excellent- Maximum fire and brilliance. Reflects nearly all of the light that enters the diamond, creating exceptional sparkle and life.

Very Good - Properly reflects most of the light that enters the diamond, producing superior fire and brilliance. Under normal lighting conditions, appears very similar to Excellent Cut.

Good - Reflects a majority of the light that enters the diamond, for an above average appearance.

Fair - Allows much of the light entering the diamond to escape from the sides or bottom, reducing perceived fire and brilliance.

Poor - Allows most of the light entering the diamond to escape from the sides or bottom. The diamond may appear noticeably dull and lifeless, even to an untrained eye.

The luminescent factor of diamond is also based on the three different types of cuts.

The three types of cut are -

Shallow cut- Fairly transparent but with a noticeable lack of sparkle.

Deep cut- The cut is excellent and emits the highest level of brilliance.

Ideal cut- The brilliance level is a bit dull.
