Round Diamond Engagement Rings

Compared to other diamond cuts, round cut diamonds are known for their rarity, level of craftsmanship and elevated brilliance. However, oval diamonds, which are more affordable, also offer a flattering silhouette with both modern and timeless appeal. Choosing between the two will vary depending on your preferences, lifestyle and your budget.

Most gem experts consider a 3-carat round diamond to be relatively large. However, choosing the ideal carat size is based on personal choice and what would best suit the design of your ring. If you feel unsure about which carat size to choose consider your partner's style and taste in jewellery or consult with one of our expert designers to help you choose. They will be delighted to assist.

A good size for a round diamond usually ranges above 0.75ct or 5.8mm. Ideally, the best size you choose for your round cut diamond engagement ring is the one that suits you and your partner's preferences as well as your budget.

Round diamonds are usually more expensive than other diamonds for several reasons. They are the most popular shape, especially for engagement rings, which means demand for them is high. The cutting process also requires removing more of the rough diamond to achieve a round shape, leading to more waste. In addition, round diamonds are cut to maximise their sparkle and brilliance, which adds to their appeal and also to cost.

When crafted, round cut diamonds have the potential to look larger than other shapes. When a cut is too deep, the diamond will have less shine, making it appear smaller than other stones of the same carat weight. Expert jewellers determine the ideal depth based on the stone’s shape, ensuring the round diamond allows light to bounce around the facets, creating the eye-catching brilliance for which the stone is known.

Traditionally it’s suggested couples spend around two to three months' salary on an engagement ring. However, this is very much an individual choice and some couples may choose alternative options that better suit their financial goals and priorities. At DX Diamonds we’ll ensure you get value for money without compromising on quality and craftsmanship.
