Round Shaped Diamonds

The first round diamond cut, known as the "old mine cut," emerged in the late 17th century, but it was not until the early 20th century that the modern round brilliant cut was developed and perfected. This transformation is largely credited to Marcel Tolkowsky, a mathematician and gemologist who, in 1919, published his seminal work on the optimal proportions for maximizing a diamond's brilliance and fire. Tolkowsky's calculations laid the foundation for the round brilliant cut, which features 58 facets strategically arranged to enhance the stone's light performance. This cut quickly gained popularity throughout the 20th century due to its unparalleled sparkle and timeless appeal. By the mid-20th century, advancements in cutting technology and increased consumer demand solidified the round brilliant cut as the most popular and sought-after diamond shape, a status it continues to hold today.

Its symmetrical, circular shape makes it a versatile choice for various types of jewellery, particularly engagement rings. The precise proportions and angles of a well-cut round brilliant diamond ensure optimal light performance, making it appear bright and lively from every angle. This timeless and classic cut remains a favourite among consumers for its unmatched radiance and elegant appearance.
