In order to select your perfect diamond engagement ring, it can be helpful to understand the difference between diamond shape and diamond cut: two properties which are often confused.


The diamond shape refers to the outline shape of the diamond as you look at it from the top down. Round, Oval, Princess, Emerald, Cushion, Heart, Marquise, Asscher, Pear, Trapeze and Baguette are all shapes, and are often referred to as ‘fancy shapes’. When selecting the perfect shape for your diamond engagement ring several factors can guide you: The ring style you covet, your partner's ring size, or simply the design that captures your heart. 


The cut of a diamond is one of the 4Cs of diamond quality, along with Clarity, Color and Carat. It does not refer to the diamond’s shape, but rather its proportions, symmetry and how well it has been cut and polished. In turn, these affect how much light the diamond emits, which will determine the degree to which it sparkles. These different types of light reflection are referred to as brilliance, fire (flashes of color), and scintillation (how light reflects with movement).
