The Round Brilliant cut diamond will always be the most desired and classic cut for engagement rings. It is loved 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. During the Edwardian, Victorian and Art Deco era’s, the round shaped diamond cut was known as the Old European cut; it wasn’t until 1919 that the Round Brilliant cut was invented by Marcel Tolkowsky and from there, the brilliance of the Round Brilliant cut has been refined more and more.
The Round Brilliant cut is the most expensive cut, not only due to their popularity but because they have more facets than any other cut, which requires more precision work. Cutters also have to discard more of the rough diamond, so you pay for a bigger diamond than you end up with.
The Round Brilliant cut diamond is by far the most popular and most researched stone cut available today, making up for over two thirds of all diamonds sold. For almost 100 years, diamond cutters have been using advanced theories of light behaviour and precise mathematical calculations to optimise the fire and brilliance of the Round Brilliant cut. The crème de le crème cut for this beloved shape is known as Hearts and Arrows, which is our standard cut grade for our Ethica Diamonds, and also known as “Ideal”.
We have a collection of Round Brilliant engagement rings,  as well as the option to purchase a loose Round Brilliant Cut Ethica Diamond or sustainably grown Round Brilliant Cut lab grown diamond.
