Diamond Shapes

The shape of the main diamond can change the entire look of a ring, creating an effect that’s vintage or modern, subtle or extravagant. Diamond cuts also affect the way light moves through the stone, meaning there’s a lot more to consider than first meets the eye – if you’ve chosen a raw diamond, it’s worth familiarising yourself with how its clarity and colour will work in conjunction with your favourite shape before committing.

Round Diamond Engagement Rings

As the oldest and most popular of all the diamond shapes, the Round diamond cut has been intensively researched over many years as cutters strive to achieve the most brilliant play of light possible in the stone.

Radiant Diamond Engagement Rings

The Radiant cut combines the rectangular or square shape of an Emerald cut with the brilliance of the classic Round cut. There are 53-70 facets in a Radiant cut, which create sparkle and highlight the colour of the stone. This makes it a popular choice for fancy coloured diamonds. Shop Radiant

Emerald

The base or pavilion of an Emerald cut diamond is cut with rectangular facets to create an unusual and elegant appearance. Because this shape is so open, the clarity of the stone takes on even greater importance than it does with most other shapes. Emerald cut diamonds are always rectangular, with diagonally-cut corners.
