Diamond Cut

What is Diamond Cut?

The term "cut" in the context of diamonds refers to how a diamond's facets and angles interact to reflect light. Its worth and beauty stem from its various facets' ability to reflect the most light.

White light is reflected to create brilliance.

Light disperses into the rainbow's colors like fire.

Scintillation is the sparkle created by the interaction of dark and light areas.

A great cut makes it easier to let in the most light, which reflects conscious brilliance, fire, and scintillation. Cut is important. A diamond of a higher carat weight with a poor cut may appear smaller than a diamond of a lower carat weight with a superior cut.

It is essential to comprehend the 4Cs because it enables one to assess their wants appropriately. To locate the ideal diamond, especially for an engagement ring, can be stressful. These 4Cs will serve as a guide for you when you select a conscious STEFEE diamond.

Diamond Cut Defined

The four c's of a diamond are carat, cut, clarity, and color. Cut and shape are sometimes confused. The arrangement of a diamond's facets is referred to as its cut. It has an impact on how light interacts with and is captured by the diamond's surface.

This "C," which is the sole mark involving human touch and skill, is what produces a diamond's much-desired brilliance. It is a delicate balance of proportion, symmetry, and polish.

What Are Diamond Facets?

The facets of a diamond are a little flat surface on the interior of the diamond's geometric design; however they are exceedingly complicated and unable to describe the shape of the diamond. Each diamond has many facets that allow it to reflect and absorb light.

Diamond Cut vs Diamond Shape

The most distinguishing characteristic of a diamond is typically its shape, which relates to its external, physical form. A diamond's shape can be thought of as expressing its personality; it is frequently symbolic and self-expressive.

Asscher, Cushion, Emerald, Marquise, Oval, Pear, Princess, Radiant, and Round are some of the diamond shapes available in STEFEE engagement rings. diamonds with brilliant cuts.

Angles, dimensions, symmetrical facets, brightness, fire, scintillation, and finishing touches are all considered to be part of a diamond's cut. A diamond's beauty is typically well hidden when it is in its original state, but after it is cut, its brightness is revealed. Its worth and beauty stem from its various facets' ability to reflect as much light as possible. The facets of a well-cut diamond bounce light off one another and scatter it upward. Light bounces out sideways or through the bottom of a diamond that has been cut too deeply or too shallowly. All our stones have IGI certification. Because their proportions have been optimized by empirical and quantitative data and have the strictest cut, only Round Brilliants can be graded as Ideal

Consider Emerald and Radiant shaped diamonds, for instance, and it becomes evident how form and cut differ from one another. They are both rectangular, just like the Emerald and Radiant. However, they have various cuts. The Emerald is step-cut, and when it reflects light, its long, linear facets produce a phenomenon called a "hall of mirrors." When reflecting light, a radiant will have a beautiful cut and will resemble broken ice more closely.

What Is Diamond Cut Grading?

A gemologist evaluates the cut to see if it has attained the desired quality of reflecting the maximum light and exiting in a dazzling manner.

How Is Diamond Cut Quality Determined?

The cut's quality is determined by how well light enters and leaves the table; this light should reflect brilliance, fire, and scintillation, according to gemologists. The light cannot be reflected successfully if the diamonds are cut too deeply or shallowly because it will escape from the bottom or surface, giving the object a dull appearance.

Higher cut grade diamonds will have more proportionate, symmetrical, and polished depth, culet, table, and girdle features.

The following elements can determine a cut's quality:


White light is reflected to create brilliance.

Light disperses into the rainbow's colors like fire.

Scintillation is the sparkle created by the interaction of dark and light areas.

  • Table:This is the diamond's top, flat surface.
  • Culet:¬†Pronounced cue-let, this is the tiny point where the facets of a diamond meet at the base of the pavilion.
  • Depth:This describes how "tall" your diamond is, or the distance between the "table" (the top of the diamond) and culet (the diamond's point).

Girdle: The point at which the top and bottom of a diamond meet is known as the girdle.

Precision of cut: This is the relationship between the sizes and angles of the various portions of the stone.

  • Symmetry: This is how a diamond's facets properly align and intersect.
  • Polish:Refers to the diamond's outside finish as well as the specifics and positioning of the facet shapes.

What Are Diamond Cut Grades?


Only a round brilliant cut may produce this excellent ideal cut. It is a perfectly symmetrical cut that, when viewed from the table's down and up sides, shows patterns in the form of hearts and arrows. Compared to other cuts, this cut's polishing requires a lot of time. Less than 1% of all diamonds possess this unique property.

Your budget will determine the cut of the engagement ring you wish to purchase as well as other preferences. STEFEE's recommended cut grade will be extremely good, graded, optimally attractive, and exclusive in consideration of the pricing, but another crucial aspect is that the ring cost (gold weight) should also be taken into account. one of the deciding criteria for budget cuts.

What Are Different Diamond Cuts?

The three types of diamond cuts are as follows. Remember that the quality of the cut is not determined by the type of cut.

Brilliant Cut

The triangular and kite-shaped facets that make up the brilliant cut radiate outward from the center of the diamond. Round shapes are most frequently combined with it, particularly Round Brilliant cut diamonds. However, it is also employed to create fancy diamond shapes including Cushion, Marquise, Oval, Pear, and Trillion diamonds. When reflecting light, brilliant cuts resemble broken ice or a prism in some way.

Step Cut

The step cut consists of rectangular facets that get larger outside and smaller inside the diamond. Each facet is long and linear, and when the light reflects off of it, it is said to provide the "hall of mirrors" appearance. Step cuts are frequently matched with diamonds in the Emerald, Asscher, and Baguette shapes.

Mixed Cut

True to its name, the mixed cut has both brilliant and step cut facets. When the light reflects, these cuts most closely resemble broken ice. They are typically found in "newer" diamond shapes including Princess, Cushion, and Radiant cut diamonds.

Diamond Cut FAQs

CUT and SHAPE of the diamond can be confusing sometimes, here are some FAQ’s that might help understand CUT.

How Are Diamonds Cut?

The final size of a diamond is determined by its shape. 1-carat The appearance of a marquise-shaped diamond is typically larger than that of a 1-carat Round Brilliant diamond. Cut, however, only accounts for a small portion of perceived size. A diamond will always appear smaller than its real carat weight when it has a poor cut. As a result, cut is arguably the most significant of the 4Cs; purchasing a 2-carat flawless, colorless diamond, for instance, is only worthwhile if its cut enhances its brilliance and enables it to shine brightly.

What Is The Most Expensive Diamond Cut?

The most expensive diamond is a Round Brilliant cut due to its popularity and great demand. Depending on the cut quality, brilliant cuts are typically more expensive than step diamonds. Higher demand as well as variations in the cutting process are to blame for this.

Ideal vs. Excellent Diamond Cut

Can Lab-Grown Diamonds Be Graded On Cut?

They can and should be certified after receiving a grade across the board. Buying any diamond without diamond certification is not advised.

Like their mined counterparts, lab-grown diamonds are cut and polished.
