Often referred to as brilliant or round brilliant cut. Round diamonds are the most popular diamond shape for engagement rings, accounting for more than 85 percent of all diamonds sold. Devised by Marcel Tolkowsky in 1919, round diamonds have 58 facets, allowing light to refract for unbelievable sparkle. The shape is extremely versatile and timeless, looking clean and modern in simple settings, yet equally as good in more elaborate styles. A well-set round diamond will give you the most sparkle.
