What is diamond cutting? How a shape appreciates the quality of the diamond ring?

If you need to determine the quality of a diamond, you must understand the 4 C – color, clarity, cut and carat weight. The most important of the 4 C is the cut. It refers to how the facets of the diamond interact with light. Polish, symmetry, and proportion determine the cut. A proper cut represents the beauty of the diamond. Diamonds from the Alexander Sparks, from the smallest to the largest, are cut to exacting standards.

Why is diamond cutting important?

If a diamond is poorly cut, it will appear opaque even if it has high purity and color ratings. If a diamond is well cut, it will reflect and refract light, producing maximum brilliance. At Alexander Sparks, they are committed to crafting diamonds with the most specialized proportions. In their workshops, world's most talented artisans design diamonds to exacting standards. This precision is what sets Alexander Sparks diamonds apart.

Diamond cut quality importance

Cutting is the only one of the four Cs that is affected by human hands. Two diamonds can have the same purity, color and carat weight, but the cut is what determines the superiority of each other. Simply put, cutting is responsible for the quality and degree of brilliance of a diamond.

Three factors determine the cut of a diamond – cutting precision, symmetry, and polishing. The highest degree of cut in the industry, called “triple excellent”, is given to diamonds that are excellently graded for cutting precision, symmetry and polishing. All individually registered brilliant-cut colorless diamonds used in lab grown diamond wedding rings.

Diamond cutting table

While most jewelry stores accept “excellent”, “very good”, “good”, “fair” and “bad” cuts, Alexander Sparks refuses to compromise and only accepts that the cut of their diamonds meets exceptional standards. Diamonds from other jewelry stores sometimes have cuts that are too deep or too shallow, allowing light to escape from the sides and bottom. They can also have misaligned facets, which stop the light from moving.

What is the shape of a diamond?

Diamond shape refers to its geometric appearance. Shapes are classified into two groups – round diamonds and fancy shape diamonds. Round diamonds, also known as brilliant cut, are the most traditional shape of diamonds. Fancy shape diamonds refer to any diamond that does not have a brilliant cut. Alexander Sparks offers a wide variety of diamond shapes and cuts to ensure each ring is as extraordinary as the love it represents.

Difference between cut and diamond shape

It is important to emphasize that cut and diamond shape is not the same thing. A diamond's cut is determined by how its facets interact with light. The geometric appearance of the diamond is determined by the shape. Cutting defines the shape of the rough diamond, not the other way around. The cut of a diamond's shape determines how it will shine. It is because cutting determines the number of facets in a diamond and how light passes through the stone.

Facets are the flat, polished surfaces of diamonds. They are like tiny mirrors. Each of them is precise, and proportionate to maximize the ability of the diamonds to reflect the lights. While the quality of the cut is the most important factor behind a diamond's brilliance, color and purity ratings are also important.


However, which diamond shapes shine the most? Each diamond shape has its facet and cut style, which produces varying levels of brilliance. At Alexander Sparks, they reject any diamonds with impurities visible to the naked eye. While some say that elongated shapes such as ovals, pears and emeralds look larger on the finger, others believe that the brilliance of a brilliant-cut diamond is what makes it stand out from a distance.
