While considering the cut of a diamond as the most important factor for its beauty, the cut determines the brilliance of the diamond. This is based on reflection, dispersion, and scintillation of the light. Unlike color and clarity, there is not a single grade that defines it.
The cut is the most complicated of the 4Cs. Carat weight, color, and clarity, with their value and rarity, result in a diamond’s formation. Cut precision is the result of human decision and diamond-cutting skills. Nowadays, it’s possible to have a better cut with the use of high technology in the diamond industry.
The difference between a dull lump of rock and a dazzling diamond comes down to the cut, which gives the sparkle to the stone. There are no limits to the different shapes a diamond can be cut, including round, princess, cushion, oval, marquise, pear, emerald, and heart.
Diamond cuts are rated as excellent, very good, good, fair, or poor depending on how they measure up to the following:
How does the diamond look from above and what is its face-up appearance? Is it bright? Does it have a fire?
How the Diamond Cut is Designed?
Has it been well crafted? This usually takes into consideration the polish and symmetry of the cut. Good symmetry will make a diamond bright and scintillating. The craftsmanship affects how the light passes through the diamond and reflects out of it. A good polish ensures a smooth surface to the rock.
Expert tip: Round brilliant cut diamond are perennially the most popular shape of a diamond – but they’re also the priciest. Carat for carat, you may be able to get a larger diamond for the same price, if it’s a different shape.
FACTORS FOR DETERMINING DIAMOND CUT QUALITY:
Proportions: the relative sizes and angles of the diamond’s parts and facets
Symmetry: the precision of the cut design, especially the facets
Polish: the smoothness and luster of the diamond’s surface
Raw diamonds need to be cut and polished into polished diamonds in order to be ready for sale.
The quality of a diamond’s cut is determined by various proportions. Major is How its been Faceted with reference to different proportion that Reflect best light and evenness. According to the grading scale, the cut can be poor, fair, good, very good, and excellent.
Diamond cutters are aware of how certain proportion combinations enable the diamond to capture light as well as possible and also maximize its brilliance and sparkle.
However, when faceting the rough diamond, the proportions are not the only thing that should be taken care of, as the cut influences the other features of a diamond.
Many times it is impossible to cut a diamond that is quite big and clear to exact excellent proportions. Because faceting them in an exact manner might lose much weight and we lose the even size parameters. This will not only reduce the size but subsequently also reduce its overall value. So many times in order to achieve a higher Yield out of rough the optimal and most desired result
Although these are the crucial or basic factors that determine the value and price of a diamond, there are many different factors that determine the Basic quality and value of a polished diamond.
Henceforth, you can see the reference of cut grades on a diamond certificate. Often using the GIA standards of Excellent, Very Good, Good, Fair, and Poor. For the most part, the actual measurements are found on the laboratory reports.

QUALITY ALWAYS SPEAKS FOR ITSELF.
A cut is the Diamond's Important characteristic. It has the greatest influence on Diamonds beauty and it determines what we generally think of as sparkle
As a Gemologist, I will recommend you to select the highest cut grade that fits your budget. The reason is simple: because of the Four Cs, no other character has a greater influence on a diamond’s appearance.
A diamond’s cut grade is an aim measure of a diamond’s light performance, or, what we generally think of as sparkle. When the cut of a diamond is in proper proportion the light reflects out of the diamond. Gemologists prefer this as the table. (Learn more about Diamond Depth & Table ) If the cut is too shallow light leaks out of the bottom too deep and it escapes out of the side.
