Our most asked questions about diamond shapes

Generally, diamond shapes with more facets tend to reflect more light and appear brighter, but the quality of the cut grade and proportions have the diamond play a large role.
Round brilliant cut diamonds are often considered the brightest diamond shape due to their 58 facets and symmetrical cut, which allows for maximum light reflection and dispersion. Princess cut diamonds, with their sharp corners and large number of facets, can also appear very bright and sparkly.
Other diamond shapes, such as cushion cut and oval cut diamonds, can also be very bright and brilliant when well-cut and well-proportioned. However, the brightness and sparkle of a diamond also depend on its clarity, color, and the quality of the diamond's cut. A well-cut diamond with good clarity and color will appear brighter and more sparkly than a poorly cut diamond, regardless of the diamond shape.

Diamond shapes are cut using advanced machinery that is specifically designed for cutting and shaping diamonds. The diamond cutting process is a highly specialized and skilled craft that requires precision and attention to detail.
The first step in cutting a diamond is to cleave, or split, the rough diamond into smaller pieces that can be shaped into the desired diamond shape. This is done using a specialized saw that is fitted with a blade made of diamond grit.
After the diamond has been cleaved, it is typically shaped using a process known as bruting. In this process, the diamond is shaped into a round shape using a rotating grinding wheel that is also covered in diamond grit. This process helps to shape the diamond and create a flat surface known as the girdle.
Once the diamond has been bruted, it is then faceted to create the desired diamond shape. This is done by using a series of grinding and polishing wheels, which are also covered in diamond grit. The diamond is held in a special holder, known as a dop, which allows the cutter to hold and rotate the diamond while shaping and polishing it.
During the faceting process, the diamond cutter carefully determines the number, size, and placement of the diamond's facets, which will determine the diamond's overall brilliance and fire. The diamond is cut and polished at precise angles to create the desired diamond shape and to maximize its beauty and value.

The popularity of diamond shapes can vary over time and is largely influenced by fashion trends and personal preferences. However, the round brilliant cut diamond has been the most popular diamond shape for many decades and continues to be the most popular today.
According to industry data, round brilliant cut diamonds make up over 75% of all diamond sales worldwide. This diamond shape is highly versatile and can be used in a variety of jewelry styles, from classic solitaire engagement rings to more elaborate designs.
Other diamond shapes, such as princess cut, cushion cut, and oval cut diamonds, have also grown in popularity in recent years, but none have surpassed the round brilliant cut diamond in terms of overall popularity.

The cost of a diamond is influenced by several factors, including the 4Cs (cut, color, clarity, and carat weight), as well as the demand for a particular diamond shape or cut. Generally speaking, the round brilliant cut diamond is the most expensive diamond cut.
Round brilliant cut diamonds are typically the most expensive diamond cut because they require more time and skill to cut than other diamond shapes. The round shape is designed to maximize the diamond's brilliance and fire, which means that the diamond cutter must remove more material from the rough diamond to create the desired shape and angles. This results in more waste and higher labor costs, which can drive up the price of the finished diamond.
In addition to the higher cost of production, round brilliant cut diamonds are also the most popular diamond shape, which can further drive up their price. However, it's important to note that the price of a diamond is also influenced by the quality of the stone, and a poorly cut round diamond may be less expensive than a well-cut diamond of another shape.

The "best" diamond shape is largely a matter of personal preference and what you value most in a diamond. However, the round brilliant cut diamond is considered by many to be the most classic and timeless diamond cut, and it is known for its exceptional brilliance and fire.
When choosing a diamond, it's important to consider the overall quality and characteristics of the stone, including the 4Cs (cut, color, clarity, and carat weight), as well as personal preferences and budget. A well-cut diamond of any shape can be beautiful and valuable, so it's important to choose the diamond that best suits your style and budget.
