What is an Elongated Diamond? | Buyer’s Guide and FAQs

Choosing a diamond for your bespoke engagement ring can feel overwhelming. One of our favourite styles that we recommend to couples is an elongated diamond – especially if you’re looking for a ring that sparkles without breaking the bank. Elongated diamonds are the perfect option if you want a vintage-inspired stone that still feels contemporary.

This timeless diamond shape boasts a distinctive look and is less common than mainstream silhouettes, such as the round cut diamond. The unique cutting technique used to create elongated diamonds can help them appear larger than their carat weight, making them an elegant choice for an alternative but timeless engagement ring. 

At DG & Co. Jewellery, we’ll help you create a bespoke engagement ring with a stone chosen from our collection of lab-grown and natural diamonds. In this post, we’re sharing an in-depth buyer’s guide on everything to know about elongated diamonds, including answering the most common questions from our community. 

A diamond is elongated when it has a length-to-width ratio greater than 1.15. For example, an elongated cushion-cut diamond typically has a ratio up to 1.30, while an elongated pear diamond usually has a ratio above 1.50. This ratio gives the diamond a longer silhouette than you’ll see with round and square-cut diamonds. The cutting technique can be used for a variety of shapes, including marquise, pear, emerald, cushion, and oval diamonds. 

Elongated diamonds are rising in popularity as their shape is universally flattering, giving your fingers a slimmer appearance. If you want the illusion of a larger carat size without paying for a larger stone, choosing an elongated cut is a great alternative.

There are several things to consider when choosing an elongated diamond. You’ll want to choose a length-to-width ratio that suits your personal style, while selecting the cut that maximises the brilliance of your stone. At DG & Co. Jewellery, we’ll help you find a lab-grown or natural diamond that delivers the best colour and clarity for your budget. Beyond the 4Cs, one of the most important design choices is having a setting that complements your elongated diamond.

Q. How is an elongated diamond different from a round diamond?

Elongated diamonds are longer than they are wide, giving them the appearance of having a larger carat weight as they cover a greater surface area. While round diamonds have a circular and symmetrical look, elongated diamonds focus on length.

Q. What are the most popular shapes for elongated diamonds?

Some of the most popular shapes for elongated diamonds include cushion cut, oval, and emerald diamonds. These shapes are ideal if you want a diamond that’s guaranteed to sparkle.

Q. Do elongated diamonds look bigger than circular diamonds of the same carat weight?

Elongated diamonds appear larger than other diamond shapes as they cover a larger surface area and have greater length-to-width proportions, usually with a ratio of at least 1.15 to 1.50+. We recommend this diamond shape if you want to maximise the value of your chosen lab-grown or natural diamond.

Q. What is the ideal length-to-width ratio for an elongate diamond?

There are no set rules for a ‘perfect’ length-to-width ratio, as this usually comes down to personal preference and your chosen diamond style. A higher ratio will give your diamond a longer look, while a lower ratio can make the diamond appear more balanced. Emerald and radiant cuts typically have a ratio of at least 1.30, while oval diamonds have a higher ratio closer to 1.50. 

Q. What setting should I choose for my elongated diamond?

Once you’ve chosen your diamond shape, our team will help you select the perfect setting for your custom engagement ring. East-west settings are one of the major trends for 2025 and beyond, while a bezel setting can help protect your elongated diamond. 

Q. How should I choose an elongated diamond to suit my finger size?

Whether you’re designing your own engagement ring or getting ready to propose to your partner, there are a few styling tips to consider when selecting the best diamond for different finger sizes. 

Emerald cuts are ideal for wider fingers as they have a structured silhouette, while oval cuts give the illusion of naturally slimmer fingers. If you’re designing your own engagement ring, our team will help you choose the best elongated diamond to suit your fingers and hand shape.
