A Glimpse into History

The Round Brilliant Cut's journey began in the early 20th century, a culmination of years of experimentation and refinement in diamond cutting. Marcel Tolkowsky, a Belgian engineer and diamond cutter, is credited with developing the cut in 1919.
His groundbreaking work, "Diamond Design," laid out the mathematical formulas that defined the ideal proportions and angles for maximizing a diamond's brilliance and fire. Tolkowsky's design set the standard for what would become the most popular diamond cut in the world.

Defining Characteristics

The Round Brilliant Cut is renowned for its ability to maximize light reflection, creating unparalleled sparkle and brilliance. 

The cut features 58 facets (or 57 if the culet is excluded), strategically arranged to reflect as much light as possible through the top of the diamond. 

This intricate facet pattern is divided into three main parts: the crown (top), the girdle (widest part), and the pavilion (bottom).
