Cut - 4Cs of Diamonds

Cut Grade - The 4Cs of Diamonds - Soha Diamond Co.

What is cut grade? 

Think of cut as the architectural blueprint of the diamond, not to be confused with the shape. There are many factors that make up the cut of a diamond. But the essence of a diamond is literally measured by its interaction with light, specifically retention and reflection of light. 

How it is graded?  

Grading is done "face-up" and takes place on a scale from Excellent to Poor. Each grade reflects a defined range of proportions sets and appearances.

What is brightness, fire, & scintillation?

The appearance of a diamond depends more on its cut than anything else.

Brightness is commonly referred to as "brilliance" and is the effect of light from the diamonds external and internal reflections. 

Fire is the dispersion of light into the colors of the spectrum.

Scintillation is the pattern and flashes of light and dark areas

As a general rule, the higher the cut grade, the brighter the diamond. 

Can I tell a difference? 

Generally, yes. Cut grades ranging from Good, Fair, and Poor will inhibit the interaction with light and therefore negatively affect the overall attractiveness.

A beautifully finished diamond is dazzling, with every facet displaying the craftsman’s skill and care. When a diamond interacts with light, every angle and every facet affects the amount of light returned to the eye.

Pricing Dynamics 

Large diamonds are more rare than small diamonds. The more scarce something is, the more it is worth. So a larger stone doesn’t just cost more. It also costs more per carat. A 1-carat diamond weighs the same as four 0.25-carat diamonds. But even if all the other quality factors are equal, the larger diamond is worth much more than the sum of the four smaller diamonds.
Increasing cut grade makes a diamond rare and affects the value

Subtle differences in cut grade can dramatically af­fect diamond value. Two diamonds of the same carat weight, color, and clarity can differ in value based on cut grade alone
