What is an Elongated Cushion Cut?

An elongated cushion cut diamond combines the soft, rounded edges of a cushion cut with the elegant, lengthened shape of an elongated diamond. This unique cut offers a sophisticated blend of vintage charm and modern appeal, making it a popular choice for engagement ring shoppers and fashion lovers alike.

The elongated cushion cut features a rectangular silhouette with gently rounded corners, creating a timeless appearance that maximises the diamond’s brilliance while showcasing an extended shape. Known for their distinctive look, these diamonds provide an ideal balance between a traditional cushion cut and a more contemporary elongated diamond.

Elongated Cushion Cut Diamonds Pros & Cons

Elongated Cushion Cut diamond pros cons


1. Unique Appearance: The elongated cushion cut combines vintage charm with a modern twist, resulting in a distinctive and elegant look.

2. Larger Face-Up Appearance: Due to their elongated shape, these diamonds appear larger than their carat weight suggests, offering excellent value for money.

3. Versatility: Elongated cushion cut diamonds complement various ring settings and styles, making them a versatile choice for engagement rings.

4. Brilliance: The unique cut maximises the diamond’s brilliance, ensuring a stunning sparkle that catches the eye.

5. Flattering Shape: The elongated shape can create a slimming effect on the finger, making it an ideal choice for those with shorter or wider fingers.


1. Rarity: Elongated cushion cut diamonds are less common, which can make them more challenging to find.

2. Bow-Tie Effect: Some elongated cushion cut diamonds may exhibit a bow-tie effect, where a dark area appears across the centre of the diamond. Careful selection and expert cutting can minimise this issue.

3. Durability: The rounded corners of the cushion cut make these diamonds more resistant to chipping than sharp-edged cuts, but they may still be more vulnerable than round diamonds.

Are Elongated Cushion Cut Diamonds Rare?

Elongated cushion cut diamonds are less common than traditional cushion or round cuts, which adds to their unique appeal. Their rarity results from the specific cutting techniques required to achieve the perfect balance between elongation and brilliance. These diamonds offer a distinctive and sophisticated choice for engagement rings, appealing to those who appreciate individuality and elegance.

Are Elongated Cushion Cut Diamonds More Expensive?

While elongated cushion cut diamonds are not necessarily more expensive than other diamond cuts, their rarity and unique appearance can influence their price. Factors such as carat weight, clarity, colour, and the quality of the cut will also affect the overall cost. 

In general, elongated cushion cut diamonds offer excellent value for money, providing a larger appearance per carat compared to round or square-shaped diamonds. This makes them an attractive option for those seeking a stunning and impressive engagement ring without beyond the budget.

What is the Ideal Ratio for an Elongated Cushion Cut?

The ratio of an elongated cushion cut diamond is crucial in determining its overall appearance. The most popular length-to-width ratio for elongated cushion cut diamonds typically ranges between 1.15 to 1.30. A ratio closer to 1.15 offers a more subtle elongation, whereas a ratio closer to 1.30 provides a more pronounced rectangular shape.

When selecting an elongated cushion cut diamond, consider your personal preferences and how the diamond will complement your chosen setting. A lower ratio may suit those who prefer a more classic, cushion-like appearance, while a higher ratio is ideal for those seeking a modern, elongated look.

Elongated Cushion Cut vs Other Cuts

Elongated Cushion Cut vs Oval

Both elongated cushion cut and oval diamonds offer an elegant, elongated shape. However, the key differences lie in their overall appearance:

  • Shape: An elongated cushion cut has rounded corners and a more vintage appeal, whereas an oval diamond has smooth, continuous curves and a modern look.
  • Brilliance: Both cuts are known for their brilliance, but the faceting pattern of the cushion cut may result in a slightly different light performance compared to the oval.
  • Style: Elongated cushion cuts are often preferred for their unique, antique appearance, while oval cuts are more contemporary and versatile.

Elongated Cushion Cut vs Radiant

Radiant cut diamonds share a similar rectangular shape with the elongated cushion cut, but they differ in their faceting and overall style:

  • Facets: Radiant cuts have more facets and a distinctive crushed-ice appearance, while cushion cuts feature larger facets that create a chunky sparkle.
  • Corners: Radiant cuts have straight edges and cropped corners, giving them a more angular look compared to the soft, rounded corners of the cushion cut.
  • Brilliance: Both cuts offer excellent brilliance, but the radiant cut’s faceting pattern may result in a slightly more intense sparkle.

Elongated Cushion Cut vs Emerald

Emerald cut diamonds are known for their step-cut facets and sleek, geometric appearance. Here’s how they compare to elongated cushion cuts:

  • Faceting: Emerald cuts have long, linear facets that create a hall-of-mirrors effect, while cushion cuts have a brilliant-cut faceting pattern that maximises sparkle.
  • Style: Emerald cuts offer a sophisticated, Art Deco-inspired look, whereas elongated cushion cuts blend vintage charm with modern elegance.
  • Appearance: The elongated shape of both cuts enhances the finger's appearance, but the cushion cut’s rounded corners provide a softer, more romantic look.

How to Choose an Elongated Cushion Cut Engagement Ring

When selecting an elongated cushion cut engagement ring, consider the following factors:

  • Ratio: Choose a length-to-width ratio that suits your personal style and preferences.
  • Cut Quality: Ensure the diamond has been expertly cut to maximize brilliance and minimize the bow-tie effect.
  • Clarity and Colour: Select a diamond with good clarity and colour grades to ensure a beautiful appearance.
  • Setting: Choose a setting that complements the diamond’s shape and enhances its unique features.
