1 Carat Diamond Engagement Rings

The average price of a 1-carat diamond engagement ring depends on a range of factors, from the type of diamond you choose, to the quality of its cut or colour. If you select a ring that has accent diamonds, such as a halo or trilogy, this will also drive up the price of your design.

For a classic 1-carat solitaire in white gold set with a good quality natural diamond, please expect between £2700 to £3500, excluding VAT. 

1-carat diamonds are considered a good size for any first-time client, or if you’re looking for a ring that is both bright and ideal to wear day-to-day. If you are planning a surprise proposal, know that 1-carat diamonds are a classic choice that fit a range of designs. It’s the definition of not too big, not too small the perfect (and sparkling) middle ground.

And if you are concerned about your diamond seeming a little small, you can also look into diamond shapes that maximise visible carat weight, such as the oval or pear. You can also push the carat weight up slightly by small 0.05-carat increments and see how that affects your overall price, or select a ring setting that will make your diamond seem larger, such as the halo engagement ring.  

As 1-carat diamonds are known to be a classic when it comes to engagement ring designs, practically all diamond cuts will look beautiful, the round, pear and oval being the most popular choice among our clients.

Deep cut diamonds such as the asscher may look a little smaller when compared to other shapes of the same carat weight, simply because a good portion of the diamond isn’t visible when looked at from above. However, even a 1-carat asscher diamond will look amazing when set in the ring of your choice, as it offers a unique vintage look. 

Through our diamond selection, you have access to one of the world’s largest diamond databases, meaning the choice is all yours! This, of course, is useful when you’re starting to look for the ideal diamond, but we can understand it might also be overwhelming, especially if you are preparing for a surprise proposal and you want it to be perfect.

We highly recommend you contact a specialist at 77 to guide you through the process, from selecting a ring to matching it with the diamond of your choice. No question is too small: we’re here to help.

Alternatively, you can start by learning more about diamond quality and the 4Cs, and understanding how these influence the final cost of a diamond. From there, you can play around with our diamond selection tool, comparing stones depending on a range of factors, and establishing a list of your own requirements that are important to you.

Lab-grown diamonds can be a good option for those looking to have a higher quality or larger stone, while still keeping within their budget. Lab-grown diamonds have the same visual and chemical properties as natural stones, however they are less rare and therefore their price is significantly lower. 

Before completing your purchase, we recommend you learn more about how lab-grown diamonds are made, and whether they would be a good option for you. 

1-carat diamonds suit a range of engagement ring styles, from the classic solitaire to the bright and brilliant halo. The most popular choice is a round diamond set on a simple solitaire ring. 

When you purchase a diamond, you should always make sure it is certified from a well-respected laboratory. At 77 Diamonds, we offer a range of certified diamonds by leading labs such as the GIA or IGI. The GIA (Gemological Institute of America) sets the standard for diamond quality, and as such, will provide the most accurate diamond appraisals.

Of course! Choosing the right diamond is an important step, and we understand you’d want it to be perfect. There are many rings on our website that offer real-time view of a 1-carat ring worn on a hand.

You can also use our helpful carat sizing tool (accessible via our product image gallery) to check the size and look of your chosen diamond as worn on a hand. Finally, our specialists would be happy to welcome you to a one-to-one tailored consultation, during which you’ll be able to see (and wear) a range of diamonds and ring styles.
