Getting to know the 4Cs


Diamond cut specifically refers to the quality of a diamond’s angles, proportions, symmetrical facets, brilliance, fire, scintillation and finishing details. We believe these factors hold the most influence on a diamond’s ability to sparkle, along with its overall beauty.


The colour of a diamond is measured by how white or colourless a diamond is. Depending on the diamond’s cut, carat weight and shape, the colour may vary among diamonds. An important aspect with colour is to determine whether it appears colourless in relation to its setting.


A Diamond’s Clarity grade evaluates how clean a diamond is from both inclusions and blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone.


The carat is a unit of weight, which measures how much a diamond weighs. This allows very precise measurements to the hundredth decimal place. We believe the importance of considering all these factors when deciding on your diamond.

Diamond Shapes

Which diamond shape to choose?
Diamonds come in a variety of different shapes, sizes and settings, so we want to be certain you’ll find one that’s perfectly suited to you.

Round Brilliant Cut

One of the most popular choices for engagement rings, this shape creates a stunning sparkle from just the slightest movement. The round brilliant diamond shape has 57 facets comprising 33 facets on the crown and 25 on the pavilion. Each angle of every facet is precisely calculated to reflect the most light, creating a dramatic sparkle.

Oval Cut

Oval cut diamonds are a beautiful modification on the classic round brilliant cut. This means oval cuts have a similar sparkle to the round cut diamond but become distinct through the ovals unique shape. The Oval shape elongates the finger to appear longer and thinner, complimenting a wide range of different hand shapes and sizes. Whilst oval cuts are a more recent cut from the 1900’s, it has proven to be a lasting and beloved style symbolising the longevity of your relationship.

Emerald Cut

The Emerald Cut Diamond flaunts an elongated, rectangular shape and chiselled step cuts, with straight linear facets arranged parallel to one another. To add stability and prevention of fractures, the corners of the Emerald diamond are usually cropped. These diamonds are a popular choice for those whom love a larger stone.

Marquise Cut

Also known as ‘boat-shaped’, the elongated shape of the Marquise diamond gives you a visually larger diamond, similar to the Oval shape, this can make the finger appear longer and thinner. Most Marquise rings feature a vertical placement, set in the more traditional north-south setting for a more traditional style.

Pear Shaped Cut

The pear diamond—often referred to as the teardrop or pendeloque cut—is unique to any other diamond cut. Combining the Marquise and oval cuts with one rounded end and a point on the other, its signature silhouette is instantly recognised for its breath-taking sparkle.

Princess Cut

A princess cut diamond has a square shape from the view above offering excellent brilliance and a contemporary feel. Princess cuts are amongst the highest carat diamonds and are a very popular engagement ring choice. If you prefer a maximum sparkle in a modern design, this is the ring cut for you.
