As cutters became more knowledgeable over the centuries, they learned how to subtly change the angles of each facet and their facet shape. Even a slight modification can impart a huge impact on how the diamond sparkles.

This shape is called a round brilliant, and it lives up to its name. The masterful facet arrangements optimize light performance in the stone, returning all the light back to the viewer’s eye for a jaw dropping sparkle.
