These qualities of a diamond all depend on one essential characteristic - its cut. Cut refers to a proportion and the quality of its polish and symmetry.



Diamonds are never created equal, whether it's created by nature or made synthetically in a lab.

A diamond cutter can make or break a diamond's worth; it takes a lot of skill and precision to make an ideally cut and well-proportioned stone, that can exude brilliance, fire, and scintillation.

For this reason, the diamond cut is often considered the most important characteristic, more so that its' naturally occurring counterparts, the clarity and color of the stone.

Light plays a big role when it comes to a diamond's appearance, given that one of its well-known properties is a high light dispersion and refraction, along with hardness and durability.

When the cut is poorly done, it can limit the amount of light that enters and exits the gem. The light properties are affected by its proportions, which is determined by the diamond's cut.

This is the most important factor because it can direct and affect the flow of light more than other quality factors.

If the proportions are done correctly, it can exude the maximum brilliance, fire and scintillation.

Diamond brilliance is the amount of light reflected back to your eye, and is essential in making a it beautiful.

It has two components - brightness and contract. The better proportion the diamond has, the more light is returned to your eye, and the brighter the stone will appear.

But in order to brilliant, it also needs contrast to make the light returning to your eye appear even brighter.

Fire or dispersed light refers to the flashes of color due to prismatic separation into the colors of the rainbow.

Diamonds experts have found out a long time ago that more fire is produced when a diamond's crown is steeper and its table is smaller, which is how old diamonds are cut.

But that proportion also makes it return less light, as less brightness makes it easier to see a diamond's flashes of fire. That is why a well-proportioned diamond strikes a balance between these two attributes.

Lastly, scintillation refers the intense sparkle of light as a diamond moves. These sparks of black and white can show well in good lighting environments.

Ideally, a diamond should have many pleasing sparks spread across its surface, with few dull dead patches.

Expert diamond cutters have studied the stone's properties and proportions over the last 100 years and have made improvements to increase its brilliance, scintillation and fire in order to dazzle the human eye.

There are already approximate proportions for round diamonds to achieve its best cut, and similar guidelines for other cuts are also being researched upon.

Many details must be in exact order and must be executed and managed flawlessly to create a truly beautiful diamond of excellent make.
