When it comes to diamonds, few cuts are as iconic and beloved as the round brilliant cut. Its unmatched sparkle and timeless elegance have made it the preferred choice for engagement rings and fine jewellery around the world. But this brilliant cut didn’t appear overnight; it’s the result of centuries of craftsmanship, innovation, and a relentless pursuit of perfection. Let’s take a journey through the history of the round brilliant cut diamond and discover how it became the epitome of brilliance.

The Roots: From Old Mine to Rose Cut

Before the round brilliant cut, diamond cutters worked with more rudimentary shapes that, while beautiful, didn’t quite capture the light in the same way. In the 18th and 19th centuries, the old mine cut was a popular style, with its cushion-like shape, high crown, and small table. It was a rough yet charming cut that laid the groundwork for future innovations.

Around the same time, the rose cut emerged, offering a different aesthetic. With its flat base and domed top covered in triangular facets, the rose cut was designed to resemble a blooming flower. Although it didn’t have the brilliance of today’s diamonds, it was cherished for its romantic and antique charm.

The Birth of Brilliance: The Modern Round Brilliant Cut

The leap from these early cuts to the modern round brilliant cut happened in the early 20th century, thanks to the pioneering work of Marcel Tolkowsky. In 1919, Tolkowsky’s thesis on diamond cutting revolutionized the industry. He meticulously calculated the ideal proportions and angles needed to maximize a diamond’s brilliance and fire, leading to the creation of the 58-facet round brilliant cut.

This new cut was a game-changer. It transformed the way diamonds were valued, placing a premium on brilliance and light performance. The round brilliant cut’s perfect symmetry and precise angles allowed it to reflect and refract light in ways that earlier cuts could not, resulting in the dazzling sparkle we associate with diamonds today.
