What is the round brilliant cut?
The round brilliant is a circular gemstone cut featuring 57 or 58 facets, designed to maximize brilliance and light return.
Why is this cut so popular?
This shape is considered the standard of perfection in modern jewelry. It has been mathematically calibrated to optimize light return, creating what is known as the diamond's "fire." When light enters the stone, it reflects from one facet to another before exiting through the top, providing spectacular brilliance.
It is this unrivaled ability to sparkle that makes it the number one choice for engagement rings. Whether you opt for a natural stone or a lab-grown diamond, this cut ensures that the stone will capture attention with its intense play of light.

How to wear and set a round diamond?
The advantage of the round brilliant cut lies in its versatility. Its symmetrical geometric shape adapts to all styles, from the most classic to the most avant-garde, and pairs easily with most metals. It is often set with prongs to allow maximum light in and enhance its sparkle.
That said, it is just as stunning in a bezel setting, which frames the stone with a metal border for a more contemporary look, very secure for everyday wear, and ideal if you are looking for a sleek line. Depending on the desired effect, it can also be surrounded by smaller stones for a "halo" effect that enhances its presence and style.
