Conventional wisdom says that when buying diamonds, one should focus on the 4Cs - Carat, Cut, Clarity and Colour. However, if you only had to focus on one, it should definitely be the cut. 

It is not the colour, but the cut that determines the “fire” and sparkle of a diamond. When a cut is right, a half carat diamond can stand out more than a bigger sized carat. 

Read on to find out why we say cut is the king of the 4Cs of a diamond! 

What is Diamond Cut?

Many may mistake this for a diamond’s shape. However, these are actually two separate aspects. Diamond shape only refers to the outline shape of a diamond when you look at it from the top down (i.e. round, oval, princess, cushion, etc).

On the other hand, diamond cut specifically refers to the quality of a diamond’s proportion, symmetry and polish. With a good blend of all three, this combination will determine how well the facets of a diamond can create sparkle and brilliance when they interact with light. 

Below is a comparison of a well cut diamond and a substandard cut diamond. As shown, the diamond on the left faces up whiter and reflects more light while the one on the right looks much duller in comparison and displays a rather disorderly contrast.

How to Use Cut to Pull Off a ‘Bigger’ Ring

Perhaps your budget may not allow for a 1 carat ring or higher, don’t be disheartened as there is another way to get a ‘bigger’ ring. A well-proportioned cut can make any diamond (of any size) look bigger than it actually is and enhance its surface colour. Additionally, the remaining 3Cs (carat, colour, clarity) will be uplifted in the process.

Essentially, in a well-cut diamond, a large percentage of light gets reflected back from the diamond and into the viewer’s eyes. This results in the diamond looking bright and lustrous.
