Diamond Cuts

Diamond cut refers to how a diamond has been shaped and faceted, and it plays the most important role in determining a diamond’s brilliance, sparkle and overall appearance. A well-cut diamond reflects light beautifully, creating fire and scintillation, while a poorly cut diamond may appear dull even if it has high colour and clarity grades.

The quality of a diamond cut is determined by its proportions, symmetry and polish. When these elements are precisely balanced, light enters the diamond, reflects internally and returns through the top of the stone, producing maximum brilliance. For this reason, cut is often considered the most important of the 4Cs when choosing diamond jewellery.

The most popular diamond cut is the round brilliant cut, valued for its exceptional sparkle and timeless appeal. Designed with carefully calculated facets, the round brilliant cut maximises light performance and remains the most sought-after choice for engagement rings and fine diamond jewellery.

Fancy diamond cuts offer distinctive style and individuality. Popular fancy cuts include princess, oval, emerald, pear, cushion, marquise and radiant. Each diamond cut has its own visual character, from the clean lines of an emerald cut to the soft curves of an oval or cushion cut. Certain diamond cuts can also create the illusion of greater size, making them a popular choice for those looking to maximise visual impact.

Different diamond cuts suit different jewellery styles and settings. While round brilliant and princess cuts are ideal for solitaires and classic designs, elongated cuts such as oval, pear and marquise are often chosen for their elegant proportions and flattering appearance on the hand.

Choosing the right diamond cut is a balance of personal style, desired brilliance and overall design. A well-chosen diamond cut enhances the beauty of the stone and ensures diamond jewellery that sparkles with lasting elegance and timeless appeal.
