A Cut Above: The Evolution of the Round Brilliant Cut Diamond

Diamonds have long been symbols of beauty, love, and prestige, but the way they’re cut has evolved significantly over the centuries. Among the myriad of diamond cuts, the round brilliant cut stands out as the most celebrated, thanks to its unparalleled ability to capture and reflect light. This blog delves into the rich history of the round brilliant cut diamond, tracing its journey from the early, less-refined cuts to the pinnacle of modern diamond artistry.

Early Innovations: Old Mine and Rose Cuts

The story of the round brilliant cut begins with its predecessors—the old mine cut and the rose cut. The old mine cut, popular in the 18th and 19th centuries, was the go-to shape for diamonds at the time. Its cushion-like form, combined with a high crown and deep pavilion, gave it a unique, antique charm, even though it lacked the brilliance of modern cuts.

The rose cut, another early innovation, was characterized by its flat base and domed top adorned with triangular facets. Named for its resemblance to the petals of a rose, this cut was prized for its romantic appeal, though it was more about subtle beauty than the dazzling light show we expect from diamonds today.

The Revolution: Marcel Tolkowsky and the Round Brilliant Cut

The transformative moment in diamond cutting came in 1919 when mathematician and gemologist Marcel Tolkowsky introduced his groundbreaking work on diamond proportions. Tolkowsky’s calculations on how to maximize light reflection and refraction led to the development of the round brilliant cut—an innovation that forever changed the diamond industry.

With 58 meticulously calculated facets, the round brilliant cut was designed to achieve maximum brilliance and fire, setting a new standard for what a diamond could be. This cut’s symmetrical shape and precision allowed it to reflect light in a way that no other cut could, making it the most popular diamond shape in the world.
