What Is the Most Expensive Diamond Cut?

If you're in the market for a luxurious diamond, you may be wondering which diamond cut is the most expensive. While there are various factors that contribute to the price of a diamond, the cut is one of the most significant. In this article, we'll explore different diamond cuts and uncover which one holds the title for the most expensive. So, let's dive into the glittering world of diamonds and discover the price of luxury.

Overview of Diamond Cuts

Diamonds come in a variety of cuts, each with its own unique characteristics and brilliance. The most popular diamond cut, known for its unparalleled sparkle, is the round brilliant cut. This cut features 58 facets that maximize the reflective properties of the diamond.

Another popular diamond cut is the princess cut. This square-shaped cut is known for its sharp corners and exceptional brilliance. The princess cut is a popular choice for engagement rings, offering a modern and sophisticated look.

The cushion cut, as the name suggests, resembles a cushion and is characterized by its rounded corners and large facets. This cut creates a romantic and vintage feel, making it a popular choice for those seeking a unique and elegant diamond.

The emerald cut is a rectangular-shaped cut that emphasizes clarity over sparkle. This cut features step-cut facets that create a hall-of-mirrors effect, giving the diamond a sophisticated and timeless appeal.

Lastly, the oval cut is an elongated version of the round brilliant cut. This cut offers a modern and elegant look while still maintaining the brilliance of a round diamond. The oval cut is a popular choice for those looking for a unique and eye-catching diamond.

Factors Influencing Diamond Prices

Before we delve into the most expensive diamond cut, it's essential to understand the factors that influence diamond prices. These factors include carat weight, clarity grade, color grade, cut grade, and overall quality.

Carat weight refers to the size of the diamond and is one of the most significant factors impacting its price. Generally, the larger the diamond, the higher the price.

The clarity grade assesses the presence of any flaws or inclusions within the diamond. Diamonds with fewer imperfections are rarer and, therefore, more valuable.

Color grade measures the presence of any color in the diamond. The less color a diamond has, the higher its value. Colorless diamonds are highly sought after and command higher prices.

The cut grade determines how well a diamond has been cut and shaped. A well-cut diamond reflects light beautifully and appears more brilliant and dazzling.

Overall quality takes into account all of these factors, along with additional characteristics such as symmetry and polish. The higher the overall quality, the higher the price of the diamond.

The Most Expensive Diamond Cut

Now, let's uncover the most expensive diamond cut. While it's challenging to pinpoint an absolute winner, there are a few diamond cuts that command higher prices due to their rarity and desirability.

The heart-shaped cut is a classic and romantic choice, representing love and affection. This unique cut requires exceptional craftsmanship and precision, making it one of the most expensive diamond cuts on the market.

The Asscher cut, often referred to as the "square emerald cut," is a step-cut diamond with cropped corners. It offers a vintage and elegant look and is highly sought after by collectors and jewelry enthusiasts.

The radiant cut combines the elegance of the emerald cut with the brilliance of the round brilliant cut. This cut creates a dazzling display of facets and is especially popular for engagement rings.

The marquise cut, with its distinctive elongated shape and pointed ends, is another expensive diamond cut. It creates a striking and dramatic look, making it a favorite choice for those who want to make a statement.

Examples of Expensive Diamond Cuts

Now that we know the most expensive diamond cuts let's take a look at some notable examples.

The Pink Star diamond, a stunning fancy vivid pink diamond, holds the record for the most expensive diamond ever sold at auction. This rare and radiant gem fetched a staggering price, highlighting the value associated with exceptional diamond cuts.

The Moussaieff Red diamond, known for its vibrant red color, is another prime example of an expensive diamond. This unique and rare gem is valued for its exceptional color and exquisite craftsmanship.

The Cullinan diamond, the largest rough diamond ever discovered, produced several exquisite diamonds, including the Cullinan I and II, also known as the Great Star of Africa and the Lesser Star of Africa, respectively. These diamonds showcase the craftsmanship and beauty that can be achieved with the right diamond cut.

Pricing of Luxury Diamond Cuts

So, how much do these luxurious diamond cuts actually cost? The prices of diamonds can vary significantly based on factors such as auction prices, retail prices, and overall market demand.

At auction, rare and unique diamond cuts can fetch astronomical prices due to their desirability and exclusivity. However, it's important to note that these prices may not always reflect the true market value of a diamond.

Retail prices, on the other hand, are typically more stable and predictable. Jewelers determine the price based on the diamond's characteristics, market demand, and other factors. While retail prices may not reach the heights of auction prices, they still reflect the value and quality of the diamond.

It's also worth noting that the price of a diamond can vary depending on the market conditions and fluctuations in the industry. Factors such as supply and demand, economic conditions, and consumer preferences can all impact diamond prices.


In conclusion, the most expensive diamond cut is subjective and depends on various factors such as rarity, craftsmanship, and market demand. The heart-shaped cut, Asscher cut, radiant cut, and marquise cut are all considered luxurious and command higher prices. However, it's important to remember that diamonds are a unique and individual choice, and the most valuable diamond cut is ultimately determined by personal preference. So, whether you prefer the timeless beauty of a round brilliant cut or the elegance of an emerald cut, choose a diamond that speaks to your heart and makes you feel truly special.
