Round Cut Diamonds

The round cut diamond was first introduced in the 17th century. Prior to this, diamonds were primarily cut into various shapes, such as table cuts and rose cuts. The round cut was a significant innovation in diamond cutting because it allowed for maximum light reflection and brilliance. Over time, advancements in technology have made it possible to create even more precise and symmetrical round cut diamonds.

Characteristics of the Round Cut Diamond:

The round cut diamond is a brilliant-cut diamond, which means that it is designed to maximize the amount of light that enters and exits the diamond. The round cut diamond has a circular shape and typically has 58 facets, which are arranged in a specific pattern to optimize light performance. This pattern includes a table (the top flat surface), a crown (the top of the diamond between the table and the girdle), a girdle (the widest part of the diamond), and a pavilion (the bottom of the diamond between the girdle and the culet). The precise arrangement and size of these facets determine the diamond's brilliance, fire, and scintillation.

Quality Factors of the Round Cut Diamond:

When evaluating a round cut diamond, there are several quality factors to consider. The most important are known as the 4Cs: carat weight, color, clarity, and cut.


Carat Weight:

The carat weight of a round cut diamond refers to its weight, not its size or diameter. One carat is equal to 0.2 grams, and diamonds are typically sold in fractions of a carat (e.g., 0.5 carats, 1.0 carat, 1.5 carats, etc.).


The color of a round cut diamond refers to how much color is present in the diamond. The Gemological Institute of America (GIA) grades diamond color on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the higher its value.


The clarity of a round cut diamond refers to how many inclusions (internal flaws) and blemishes (external flaws) are present in the diamond. The GIA grades diamond clarity on a scale from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and blemishes visible to the naked eye).


The cut of a round cut diamond refers to how well it has been cut and polished. The GIA grades diamond cut on a scale from Excellent to Poor. A well-cut diamond will have optimal light performance and will be more valuable than a poorly cut diamond.

Pros of Round Cut Diamonds:

  1. Timeless and Classic appeal.

  2. Excellent sparkle and brilliance.
