In this guide, we’ll walk you through some of the most popular diamond cuts and their unique qualities to help you find the ring that feels just right.

Round Brilliant Cut

The round brilliant cut is arguably the most iconic and popular diamond shape. Its meticulous faceting pattern is specifically designed to maximise light return, resulting in unparalleled brilliance and fire. If you desire a classic, elegant look with exceptional sparkle, the round brilliant is an excellent choice.

Princess Cut

For those who appreciate clean lines and a modern aesthetic, the princess cut is a captivating alternative. This square or slightly rectangular shape boasts sharp, defined corners and a brilliant sparkle. Its faceting differs from the round brilliant, resulting in a different kind of light performance and the stone often appearing larger than round brilliants of the same weight.

Oval Cut

The oval cut offers a beautiful blend of brilliance and a flattering elongated shape. Its rounded edges and extended silhouette can make the finger appear longer and more slender. Oval diamonds possess a similar fire and brilliance to round brilliants and offer a touch of vintage charm and sophisticated elegance suitable for both classic and modern settings.

Emerald Cut

Characterised by its step-cut facets and rectangular shape with cut corners, the emerald cut exudes elegance and sophistication. Unlike brilliant cuts that maximise sparkle, emerald cuts highlight the diamond's clarity and colour. Their clean lines and elongated shape create a dramatic and refined look, often favoured by those with a discerning eye for classic style.

Marquise Cut

With its elongated shape and pointed ends, the marquise cut is a truly distinctive and glamorous choice. Its shape is said to have been inspired by the smile of the Marquise de Pompadour. The marquise cut can also create the illusion of greater size and can make the finger appear longer. Its unique silhouette makes it a captivating centre stone for rings and a striking element in pendants and earrings.

Pear Cut

Also known as a teardrop, the pear cut is a romantic and distinctive choice that combines the brilliance of the round cut with the elongated elegance of the marquise. The pointed end should ideally point towards the wearer's fingertips. Pear-shaped diamonds offer a sense of individuality and grace, making them a beautiful option for those seeking something a little different.

Cushion Cut

The cushion cut, with its rounded corners and brilliant-style faceting, offers a softer, more romantic take on the square or rectangular shape. Its vintage appeal and exceptional sparkle have made it increasingly popular in recent years. Cushion cuts come in various proportions, from more square to more elongated, offering a range of aesthetic possibilities.
