Oval Cut vs. Round Cut Diamond: Choosing the Best Cut for Your Personal Style

Diamond cuts, such as the oval cut and round cut, play a significant role in enhancing the aesthetics and personal style of the wearer. The right diamond cut can elevate the overall beauty and elegance of the diamond. With so many diamond cuts to choose from, including the oval cut vs. round cut diamond, making a decision can be challenging. In this article, we will discuss these two popular diamond cuts and help you choose the best one for your personal style.

With a reputation built on integrity, knowledge, and professionalism, A.A. Rachminov has become a trusted source for discerning diamond buyers worldwide.  Whether it's an elegant oval cut or a radiant round cut, A.A. Rachminov's collection offers a diverse range of diamonds to suit a variety of personal styles.

Characteristics of Round Cut Diamonds

  • Round cut diamonds, also known as Brilliant cut, are the most popular diamond shape, accounting for more than half of all diamonds sold globally. Their symmetrical shape allows for maximum reflection of light, contributing to their exceptional brilliance.
  • The round cut diamond typically has 57 or 58 facets. This high number of facets increases the diamond's ability to reflect light, making it appear more radiant and sparkling.
  • Because of their proportion and symmetry, round cut diamonds are highly versatile and can suit multiple settings and styles, from classic solitaire rings to more contemporary designs.
  • Round cut diamonds are known for their excellent fire and brilliance. "Fire" refers to the dispersion of light into the colors of the spectrum, and "brilliance" refers to the brightness of the diamond when viewed under light.
  • Due to their popularity and the amount of rough diamond waste in the cutting process, round cut diamonds are typically more expensive than other cuts. However, their timeless appeal and shine often justify the higher price point.

Characteristics of Oval Cut Diamonds

  • Oval cut diamonds, introduced by Lazare Kaplan in the 1960s, are a unique and distinctive choice. These cuts retain much of the brilliance of round cut diamonds but offer a larger surface area, giving the illusion of a bigger diamond.
  • The typical oval cut diamond has 56 to 58 facets, allowing for excellent light reflection and a significant amount of sparkle. The elongated shape can also make the diamond appear larger than other cuts of the same carat weight.
  • Oval cut diamonds are flattering on the hand as the elongated shape can create the impression of longer, more slender fingers.
  • Due to their elongated shape, oval cut diamonds may exhibit a "bowtie effect," a slight dark area across the width of the diamond. However, this can be minimized with skilled cutting and does not necessarily detract from the diamond's beauty.
  • Compared to round cut diamonds, oval cuts are usually less expensive per carat, making them an attractive option for buyers on a budget without sacrificing sparkle or visual impact.

Comparative Analysis: Oval Cut vs. Round Cut Diamonds

  • Brilliance: Both oval and round cut diamonds are known for their exceptional brilliance due to their high number of facets. However, round cuts typically exhibit more fire and sparkle because of their perfect symmetry.
  • Size Appearance: Oval cut diamonds often appear larger than round cut diamonds of the same carat weight because of their elongated shape, which offers a larger surface area.
  • Price: Round cut diamonds are generally more expensive than oval cuts, primarily due to their popularity and the amount of rough diamond waste in the cutting process.
  • Flattering Effect: Oval cut diamonds can create the illusion of longer, more slender fingers due to their elongated shape, which is a unique aspect not found in round cut diamonds.
  • Versatility: Both cuts are versatile and can suit multiple settings and styles. However, round cut diamonds are often seen as more traditional, while oval cut diamonds offer a more contemporary and unique look.
  • Visual Characteristics: Oval cut diamonds may exhibit a "bowtie effect," a slight dark area across the width of the diamond. This characteristic is not typically seen in round cut diamonds.
Ultimately, the choice between an oval and round cut diamond comes down to personal preference. Those seeking a classic, timeless design might prefer a round cut, while those desiring a larger-looking, unique, and slightly less expensive diamond might lean toward an oval cut.


When it comes to choosing oval cut vs. round cut diamond, it is essential to consider the unique qualities of both diamonds. For those who prioritize maximum brilliance and fire, a round cut diamond may be the perfect choice. For others who want a larger-looking diamond within their budget and appreciate the unique bow-tie effect and a distinctive fire, an oval cut diamond is the way to go.

Why is the round cut often associated with maximum brilliance in diamonds?

Answer: The round cut is designed with 57 or 58 facets that optimize light reflection, contributing to its exceptional brilliance. The symmetrical shape allows for maximum dispersion of light, making the round cut diamond appear more radiant and sparkling compared to other cuts.
