Diamond Cuts

The cut refers not to the shape of the diamond, but to the actual quality and precision of the stone. Factors like symmetry, proportion and polish are crucial in assigning a grade to a diamond's cut. A diamond with high-quality cut will appear more brilliant and luminous, while a poorly cut diamond may appear dull. Many different cuts exist, including the Princess, the Emerald, and the popular Round Brilliant, which contains 58 individual facets and is the most valuable cut.


To break it down a bit more, the dimensions and symmetry of a diamond largely define the cut. When a diamond's facets are in proper alignment, light is more effectively refracted through the top of the diamond. This causes the entire stone to sparkle brilliantly. Most gemologists agree that the cut is the most important characteristic in determining the quality of a diamond, because even if the weight, color and clarity have high grades, a poorly cut diamond will still appear dull, undermining the other characteristics.


When assessing the dimensions of a diamond and how they play a role in defining the cut, it's important to understand how the wrong dimensions can have an adverse effect on quality. If the stone is too shallow, it loses light through the bottom. If the stone is too deep, it loses light through the sides. Finding the right balance ensures the maximum sparkle.


Diamond Shapes


The shape of the diamond can impact the value, but it's also a matter of personal taste. Some prefer a Princess cut, while others are fond of a smooth Oval. Other popular shapes include Round, Trilliant, Marquise, Heart, Pear, Radiant, Cushion, Emerald and Asscher. Some cuts are more rounded in their contours, while others are more straight and uniform. When it comes to diamond cuts, beauty truly is in the eye of the beholder.

Diamond Cut Styles


The style of the cut determines the crown height, depth, diameter, thickness and angles of the stone. It's an extremely delicate process, and cuts are graded on a scale of Ideal, Premium, Excellent, Very Good, Good, Fair, and Poor. The cut grade is one of the most important factors to consider when buying a diamond, because a good cut means the difference between a stunning stone and a dull rock.


Styles of Diamond Cuts


The Ideal cut grade was mathematically designed to reflect and refract light in the most thorough and effective way possible, and the grade is especially useful for Round and Princess diamonds. When purchasing a diamond, you want to ensure that your cut grade will allow for as much brilliance as possible.
