£420.00£8,000.00

The Round Brilliant cut diamond will always be the most popular and classic shape. It is beloved for its unmatched brilliance and beauty and it returns the most amount of light due to its ideal facet pattern. It resembles a simple circle, which makes it extremely versatile.

All Round Brilliant stones are consistently cut by hand to the coveted ‘Hearts and Arrows’ cut, the best you can get for sparkle and light play.
