Shape

Most commonly confused with cut, diamond shape refers to the shape in which it has been cut into and influences the complete look and feel of a given design. Choosing the shape of the diamond should be based on personal preference, although it is good to note there are some advantages to certain shapes.

Top Tips

To help you choose the perfect diamond Shape, we have collated a few top tips


It is important to select the shape of the diamond based on your personal preferences as this has an overriding effect on the look of the design. Most have a shape in mind before beginning their search, whilst others may consider shapes which they deem most flattering.
The round diamond is deemed the most popular, possibly due to its timeless appeal and tendency to generate more of sparkle when compared to other shapes.
