The round brilliant cut is the most popular diamond shape: more than half of all diamonds sold today are cut accordingly.
With 58 facets divided amongst its crown, girdle and pavilion and a typical ratio between 1.00 and 1.02, it yields maximum shine as the cut naturally follows the rough diamond crystal.
The round brilliant is the most researched cut in the industry; for more than a hundred years, diamond cutters have used advanced scientific theories of light reflection and precise mathematical calculations to optimize its fire and brilliance.
