Diamonds are one of the most popular and sought-after gemstones in the world, with their value determined by various factors such as clarity, color, carat weight, and cut. Among the different diamond cuts available in the market, the round cut is the most popular and commonly used in engagement rings and other jewelry. 

However, the question that often arises is whether round-cut diamonds are more expensive than other diamond shapes.

Introduction to Diamond Shapes: What Is a Round-Cut Diamond?

Diamonds come in a variety of shapes, each with its own unique characteristics and appeal. The round cut diamond is the most popular and well-known of all the diamond shapes. It is a classic and timeless shape that has been around for centuries and is often used in engagement rings, wedding bands, and other types of jewelry. 

The modern day lab grown round cut diamond is one of the most dazzling artificially made diamonds that fully resemble the natural diamonds. If you’re looking for ethical engagement rings then the lab grown diamond rings is your go-to alternative.

They are characterized by their circular shape, which features 58 facets, or flat surfaces that reflect light and create a dazzling sparkle. The round cut is also one of the most brilliant of all diamond shapes, meaning it has the ability to reflect the lightest and create the most fire. 

While other diamond shapes, such as the princess or cushion cut, have become more popular in recent years, the round cut remains a popular choice due to its beauty and versatility.

How Round-Cut Diamonds Are Priced

Diamond prices are determined by several factors, commonly referred to as the “4Cs”: carat weight, color, clarity, and cut. These factors work together to determine the overall quality of the diamond, which in turn affects its price. 

Here’s how each of these factors influences the price of a round-cut diamond:

Carat Weight:

When purchasing diamonds, the first thing buyers frequently take into account is the diamond’s carat weight, which is its actual weight. Because it takes more rough diamond material to cut a round-shaped diamond, they are typically more expensive per carat than other diamond shapes. The price of a diamond increases because it becomes rarer and more expensive as it grows in size.


A color scale from D (colorless) to Z is used to grade diamonds (light yellow or brown). A diamond usually costs higher the more colorless it is. Yet, a round-cut diamond’s brilliance and fire can make it simpler to spot color flaws, necessitating a higher color grade.


The diamond’s clarity is determined by the presence or absence of inclusions, or internal imperfections. A diamond will cost higher and become more valuable with fewer inclusions. Round-cut diamonds exhibit inclusions more readily than other diamond shapes. So, a higher clarity grade may be necessary to preserve their value and brightness.


Often regarded as the most crucial element in determining a diamond’s beauty and value, cut refers to the stone’s dimensions, symmetry, and polish. A well-cut round diamond will reflect the lightest, resulting in the most brilliance and fire. The weight of the diamond is also impacted by the cut; a poorly cut diamond loses weight and subsequent value.

Overall, round-cut diamonds tend to be more expensive due to their popularity and the amount of rough diamond material needed to cut them into a round shape. However, it’s important to remember that price should not be the only consideration when buying a diamond. Often, you should also take into account the beauty and quality of the stone.

Factors That Affect the Price of Round-Cut Diamonds

Round-cut diamonds are one of the most popular and sought-after diamond shapes. Usually, their price is determined by several factors that affect their quality and value. 

Here are some of the key factors that can impact the price of a round-cut diamond:

  • Material and size: Round-cut diamonds require more rough diamond material to be cut into their round shape, which means that they tend to be more expensive per carat than other diamond shapes. Additionally, the larger the diamond, the rarer it is, which also drives up the price.
  • The level of brilliance and cut: In a round-cut diamond, the brilliance, and fire can make it easier to see any color imperfections, which can impact the diamond’s value. A well-cut round diamond will reflect the lightest, creating maximum brilliance and fire, which enhances its beauty and value. On the other hand, a poorly cut diamond will not reflect light as well and may appear dull, making it less valuable.
  • The presence or absence of inclusions or blemishes in a diamond. The fewer inclusions a diamond has, the more valuable it is. However, in a round-cut diamond, inclusions can be more visible due to the way light reflects off the multiple facets, so a higher clarity grade may be necessary to maintain its value.
  • Fluorescence: Fluorescence is a visible reaction to ultraviolet light that some diamonds exhibit. While fluorescence can enhance the beauty of some diamonds, it can also reduce the value of others. The impact of fluorescence on a diamond’s price depends on its intensity, color, and how it affects the diamond’s appearance.
  • Certification: Diamonds that are certified by reputable organizations like the Gemological Institute of America (GIA) or the American Gem Society (AGS) are generally more valuable. Certification assures buyers that the diamond has been accurately graded and can be trusted to meet industry standards.
  • Market demand: Finally, market demand can also affect the price of a round-cut diamond. If a particular diamond shape or style is in high demand, the price may increase due to supply and demand dynamics.

Comparing Round-Cut Diamonds to Other Diamond Shapes in Terms of Price

The following are some key differences between round-cut diamonds and other diamond shapes in terms of price:

  • Round-cut diamonds tend to be more expensive per carat than many other diamond shapes, including princess, cushion, and pear shapes. This is because more rough diamond material is lost during the cutting process to create a round shape.
  • Some diamond shapes, such as marquise, oval, and pear shapes, may appear larger than a round diamond of the same carat weight due to their elongated shape. This can make them a more cost-effective option for buyers who want a larger-looking diamond without paying for the additional carat weight.
  • Fancy-shaped diamonds, such as heart, emerald, and Asscher shapes, may have a lower price per carat than round diamonds due to lower demand. However, they may also require a higher clarity grade to maintain their value due to their more open and transparent cut.
  • Princess-cut diamonds are a popular alternative to round diamonds and can offer a similar level of brilliance and fire. While they may be slightly less expensive per carat than round diamonds, they may require a higher color grade to maintain their value due to how their cut can make color imperfections more visible.

The Popularity of Round Cut Diamonds: Why They May Be More Expensive

Due to their popularity, round-cut diamonds tend to be more expensive than other diamond shapes, even when compared with diamonds of the same carat weight, color, and clarity. 

The following are some reasons why round cut diamonds may be more expensive:

  1. High demand: As mentioned, round cut diamonds are the most popular diamond shape, which creates a higher demand for them. Higher demand can drive up the price of any product, including diamonds.
  2. Loss of rough diamond material: During the cutting process, more rough diamond material is lost to create a round diamond shape compared to other diamond shapes, such as princess or cushion cuts. This results in a higher cost per carat for round-cut diamonds.
  3. Superior light performance: Round-cut diamonds are designed to maximize the reflection and refraction of light. This creates superior brilliance and fire compared to other diamond shapes. The same requires precise cutting and polishing, which can increase the cost of production.
  4. Diamond cutting technology: To achieve the perfect symmetry and proportions required for a round diamond’s ideal light performance, diamond cutters need to use advanced technology and techniques, such as computer-aided design and high-precision laser cutting. These additional steps increase the cost of production.
