Round

When we think of love, marriage and proposals, it’s the round brilliant diamond that first comes to mind. The round brilliant is the most popular diamond shape, representing almost 75% of diamonds sold.

Best known for its brilliance, this cut has 58 angular facets, which cause light to bounce from the bottom of the diamond back through the top, giving it unbelievable sparkle. Because of this, it’s become a time-honored engagement tradition. It’s versatile shape suits all styles and metals.

The popularity of the round brilliant paired with the amount of waste produced during cutting, means that these diamonds carry the highest premium.
