Round Cut Lab Grown Diamonds
The round cut of a lab-grown diamond is considered the best by many due to its symmetry and ability to maximize light reflection and refraction. The round shape has 57 or 58 facets, which allows for the greatest number of reflective surfaces, resulting in a diamond that is extremely brilliant and sparkly.
Additionally, the round shape is the most versatile and can be set in a variety of different jewelry styles, making it suitable for any occasion. The round shape is also the most popular lab-created diamond shape, and has been for several decades, which means that it holds its value well and is more likely to be resold in the future.

The origins of the round diamond shape can be traced back to the late 19th and early 20th centuries, as a result of advancements in cutting and polishing methods. Prior to this, diamonds were typically cut into more primitive shapes, such as the "old mine" or "old European" cuts. These early diamond cuts had a smaller table, higher crown, and a deeper pavilion than modern round diamonds, resulting in a less brilliant stone.
In 1919, Marcel Tolkowsky, a Belgian diamond cutter, published a treatise on the ideal proportions for a round diamond, which is known as the Tolkowsky Cut or the American Ideal Cut. Tolkowsky's calculations were based on mathematical principles of light reflection and refraction, and his ideal cut maximized the diamond's brilliance and fire. This cut became the standard for round lab-created diamonds too and is still used today as a benchmark for diamond cutting and grading.
The round diamond shape quickly gained popularity in the 1920s and 1930s, and has remained the most popular diamond shape to this day. The round shape became more popular because of its symmetry, which allowed for the maximum reflection of light, creating a sparkling and brilliant stone.
So, the round shape of diamond came from the process of cutting and polishing, the Tolkowsky Cut is considered as the standard for round lab-grown diamonds, and its popularity is due to its symmetry which maximize the reflection of light and creates a sparkling and brilliant diamond.
