When it comes to diamond cuts, two of the most popular types are the brilliant cut and the step cut. Both styles have unique characteristics and qualities and can have a significant impact on the overall appearance of a diamond. Brilliant cut vs step cut diamonds, let’s explore the differences between the two.
What Is a Brilliant Cut Diamond?

A brilliant cut diamond is a diamond that has been cut in a way that maximizes its brilliance and fire. This is achieved by creating a pattern of triangular facets on the diamond’s surface that allows light to enter and reflect back out in a way that creates a beautiful display of light and sparkle.
The history of the brilliant diamond cut can be traced back to the early 17th century. At the time, diamonds were primarily used for their value as a currency, and their cut was not a major consideration. Diamonds were typically cut into simple shapes, such as table or point cuts, designed to maximize their weight rather than beauty.
It was not until the 17th century that diamond cutting began to evolve into an art form. A Venetian diamond cutter named Vincenzo Peruzzi is credited with creating the first true brilliant cut. Peruzzi realized that by cutting a diamond in a way that reflected more light, he could enhance its beauty and value. He experimented with various cuts, eventually developing a style that incorporated a series of triangular facets that allowed light to enter the diamond and reflect back out, creating a beautiful display of light and sparkle.
The brilliant cut gained popularity throughout the 18th and 19th centuries, as diamond-cutting techniques continued to evolve. In 1919, Marcel Tolkowsky, a Belgian mathematician and diamond cutter, published a thesis on diamond cutting that revolutionized the industry. Tolkowsky’s research revealed the optimal proportions for a brilliant cut diamond, including the number of facets and their angles, which have since become the standard for modern diamond cutting.
The most popular type of brilliant cut diamond is the round brilliant cut. Other popular types of brilliant cuts include the oval cut, the pear cut, the cushion cut, the princess cut, the radiant cut, the marquise and the heart cuts.
Today, the brilliant cut is one of the most popular diamond cuts and is used in a wide variety of jewellery, including engagement rings, necklaces, bracelets, and earrings. Its ability to maximize a diamond’s beauty and sparkle has made it a timeless classic, a symbol of enduring love and commitment.
What Is a Step Cut Diamond?

A step cut diamond is a diamond that has been cut in a way that emphasizes its clarity and lustre. This is achieved by creating long, rectangular facets on the diamond’s surface arranged in parallel lines, creating a hall-of-mirrors effect and giving the diamond a clean and sophisticated look. This type of diamond cut is characterized by its clean lines, straight edges, and truncated corners.
The first step cut diamonds were developed in the 16th century, and they quickly gained popularity due to their clean lines and symmetrical shape. The early step cut diamonds were not as precise as modern cuts, but they still had a unique appeal and were often used in jewellery worn by royalty and aristocrats.
In the 18th and 19th centuries, diamond-cutting techniques continued to evolve, and the step cut became increasingly popular. The emerald cut, now the most popular type of step cut diamond, was originally developed for emeralds but was soon adapted for use with diamonds as well. Other types of step cuts include the baguette cut, the trapezoid cut, and the Asscher cut.
Today, step cut diamonds are still highly prized for their understated elegance and sophisticated beauty. While they may not have the same level of sparkle as brilliant cut diamonds, their unique hall-of-mirrors effect and ability to showcase a diamond’s natural beauty and clarity make them a popular choice for engagement rings and other fine jewellery.
Brilliant Cut vs Step Cut Diamonds

A brilliant cut diamond is designed to maximize its brilliance, fire, and sparkle. It is the most popular diamond cut and features many facets that reflect light in a way that creates a brilliant and dazzling effect. The facets are typically arranged in a circular pattern, which allows the light to bounce around and create a kaleidoscope of colour and sparkle.
One of the key benefits of a brilliant cut diamond is that it can hide any flaws or inclusions in the diamond, making it appear flawless. The many facets of the cut can also create the illusion of a larger diamond, as the light reflecting off the facets makes the diamond appear bigger.
A step cut diamond is designed to showcase the diamond’s clarity and lustre rather than its sparkle. It usually features a rectangular or square shape with large, flat planes or facets that are arranged in parallel lines. The step cut is known for its elegant and refined appearance, with a more understated sparkle than the brilliant cut.
One of the main advantages of the step cut is its ability to showcase a diamond’s clarity. The flat planes of the cut make it easier to see any inclusions or flaws in the diamond, and this also means that a diamond with higher clarity is needed to make the most of the cut.
When choosing between a brilliant cut and a step cut diamond, there are several factors to consider. Brilliant cut diamonds are often more expensive than step cut diamonds because they require more precise cutting and waste more rough diamond material. However, they are also more popular and have a more classic and timeless appeal. Step cut diamonds, on the other hand, are often more affordable than brilliant cut diamonds because they waste less rough diamond material.
When choosing between a brilliant cut and a step cut diamond, it ultimately comes down to personal preference. If you are looking for a diamond with maximum sparkle and brilliance, a brilliant cut diamond may be the best choice. However, if you prefer a more understated and elegant look that emphasizes clarity, a step cut diamond may be the way to go.
It is important to keep in mind that no matter which cut you choose, be sure to work with a reputable jeweller and carefully evaluate the quality of the diamond you are considering to ensure that it meets your expectations and desires.
