Diamond Shapes

When looking for an engagement ring, you’ll particularly want to consider the different types of diamond cuts available. Despite not being one of the key 4 C’s of diamond quality, the diamond shape will have the most influence on the style of your ring.

More correctly labeled as diamond shapes, so as not to be confused with the diamond cut scale which measures how well a diamond has been cut  as opposed to the way the stone is cut into different diamond shapes.


Round Brilliant

Round diamonds offer the perfect balance between size, brilliance and versatility, while being a ‘safe’ choice when choosing for your partner. 

Aim for at least ‘Very Good’ cut, polish and symmetry grades to ensure a high brilliance diamond.


Emerald shaped diamonds are elongated straight edged diamonds with cut corners and a ‘step’ cut. The step cut means there are fewer but larger facets that act as mirrors for reflecting light.

Emerald cuts should be purchased with high clarity to ensure they are eye clean. The recommended choice of diamond color grade will depend on the jewelry metal.


There are many ways to cut a cushion cut diamond and the facets may appear similar to a brilliant cut round, have a vintage ‘old mine’ look or an appearance of crushed ice. Seeing the exact stone before buying is recommended. 

We offer square ratio brilliant cushion cuts as standard.


Ovals are simply an elongated version of the round brilliant cut. High brilliance, rounded edges but with a subtle twist.

Oval cuts are one of the more popular of the fancy shapes with the ideal combination of price, size and brilliance, together with the soft rounded edges.

Oval cut diamonds are also an excellent choice for elongating the appearance of the finger.

Marquise cut diamonds have the largest surface area per carat and offer excellent value for money in that respect as you can opt for a lower carat weight and save, compared to other shapes.

They’re considered a more vintage or alternative choice of diamond shape.

Teardrop Shaped


Pear shaped diamonds, also known as teardrop diamonds have a rounded edge on one side and a point at the other. Similar to ovals these too are excellent for accentuating the slender appearance of fingers when worn.

Lower colored pears (J-K) are less recommended as the color tint can concentrate in the narrow area of the stone.

For the diehard romantics, there’s nothing that beats the heart shape. Hearts, however, aren’t the most popular engagement ring styles and so design options are relatively limited when compared to some of the different diamond cuts.

Square Princess

To get a square diamond, you'll want to look for a width-length ratio of 1-1.05.

Princess cut diamonds are not graded for cut by the GIA as there are no 'ideal' measurements, but do have a polish and symmetry grading. 

Aim to avoid very deep cut princess cuts as your diamond will appear significantly smaller.

Other shapes include...

While our currently collections don't include these shapes, we do love them! Each one has its unique character and style and we hope to play with these in the future.

Radiants are very similar in shape to emeralds, but are brilliant cuts. They therefore have more facets and more sparkle to them. Radiants come in elongated and square radiant form. With radiant cut diamonds you can comfortably purchase SI quality for an eye clean stone.

Asscher cut diamonds are equal ratio square shaped emerald cuts. They too have a step cut and should be carefully selected with high clarity. While a typically sophisticated choice, asscher cuts do appear smaller than other shapes with the same carat weight.

Baguettes are rectangular cut diamonds, usually made in smaller sizes that are rarely set as the centerpiece. Baguettes look very similar to step cut emeralds but without the cut corners. The length width ratio has the most significant effect on the appearance and price of baguette cut diamonds.

Trillion diamonds are triangles that typically are cut with slightly rounded edges for a more appealing aesthetic. These too are relatively uncommon and supply of both diamonds and designs is limited.

Which diamond cuts (shapes) do you carry?

Our collections are designed with rounds, square princess, ovals, emerald, pear shaped, heart and marquise.

Does the shape affect size?

For each carat weight, you'll get a smaller or larger surface depending on the shape. Our carat weight chart shows popular shapes and their average sizes.

Does the shape change the value?

Different shapes use a different amount and shape of raw diamond, therefore their raw cost can differ. However, the main influence on price and value is supply and demand for each shape.
