Excellent Cut Diamonds
The cut of a certified diamond measures its proportions, craftsmanship, quality of polish, and light reflecting properties. An excellent cut diamond boasts a high-quality polish and symmetry and will reflect all light as brilliance and fire. Excellent cut diamonds are a great value because they are considered very high quality but will not be as costly as Ideal cut diamonds.

Diamond Cut
One of the most defining characteristics of a diamond is its cut. While high grades of color, clarity, and carat weight also contribute to a diamond's appeal, it's the cut that determines the symmetry of the stone's facets, its overall proportions, and its ability to reflect light. An expertly cut loose diamond will achieve high levels of brilliance, sparkle, and durability. Even if a certified diamond is graded well in other areas, a poor cut can result in a dull, muted effect.
Light & Cut
There are many factors that determine a diamond's brilliance, the most important of which is its ability to reflect light. When light enters the surface of a diamond, a portion of it is reflected back out of the top. The remaining rays of light travel into the center of the diamond and bounce off its internal walls, an effect known as refraction. As light exits the diamond, dispersion causes the white light to be separated into multiple colors. Some light will escape out the bottom and sides, and some will reflect out of the top of the stone. The light that is reflected is referred to as the 'fire' of the diamond.
As a diamond is moved through a light source, tiny flashes will be visible within the stone. Commonly known as sparkle, this is also referred to as scintillation, an effect of the stone's reflection and refraction of light.
It's the diamond cut that determines how much light is reflected back to the wearer, directly impacting its brilliance and fire. Diamonds are generally categorized into three main types of cuts:
- Shallow cut: Although a shallow cut diamond will create the illusion of a larger stone, it allows light to escape out the sides instead of reflecting off the top, creating a lack of brilliance and sparkle.
- Deep cut: This type of cut poorly reflects light, resulting in a dull, muted appearance.
- Ideal cut: This premier cut style is well-proportioned and carefully angled to achieve a luminous appearance.
Polish, Symmetry, Cut Grade
A certified loose diamond's polish and symmetry are critical to the quality of its cut. For maximum brilliance, every facet of a diamond should be professionally polished after the cutting process. A high-quality polish will leave little to no scratches and marks, while a poor polish can result in imperfections on the surface of the diamond, which detract from its value.
A symmetrical diamond will have well-balanced, properly aligned facets, resulting in a high level of fire and brilliance. If the facets are not symmetrical or are not optimally shaped, they'll display less sparkle.
A gemologist assigns a cut grade as a means of measuring a diamond's proportions, craftsmanship, quality of polish, and light reflecting properties. A diamond with a high quality cut grade will exude a large amount of brilliance and fire.
A diamond's ratings for polish, symmetry, and cut grade may vary based on which Gemological Laboratory is evaluating it, as each agency uses a different scale.
Cut & Value
The quality of a diamond's cut has a significant impact on its value. A well-cut stone sacrifices more of the rough diamond during the cutting process, resulting in a higher market value. It will also exhibit better light reflecting properties, exuding greater fire and brilliance. Improperly cut loose diamonds will have less visual appeal and a decreased value. To ensure the best value, look for a certified diamond with polish and symmetry ratings of 'Good' or better.
