1.5 Carat Diamond Engagement Rings

The price of a diamond can be difficult to pinpoint, as so much depends on the quality of the centre stone and the type of ring setting you choose. On average, a very good quality 1.50-carat diamond engagement ring can cost anywhere between £8000 to £15 000, excluding VAT. Prices can be even higher if you choose a rare diamond, or match your centre stone with a bespoke ring design. 

Although weighing only 0.1g more than a classic 1-carat diamond, 1.50-carat are considered to be larger, and they are visually quite different to smaller stones. However, they are not considered to be excessively large or overbearing. Their size still allows for delicate and chic engagement ring designs that can easily be worn day-to-day.

Set with a slightly larger stone, the 1.50-carat diamond engagement ring offers a lot of versatility when it comes to ring styles. A classic solitaire will always complement a 1.50-carat diamond and offer that delicate, more minimalist touch so fashionable today. Alternatively, a halo engagement ring will offer eye-catching sparkle, and make your centre diamond seem even larger. 

A 1-carat round diamond will be around 6.4 mm in diameter, while a 1.50-carat will be roughly 7.3 mm to 7.4 mm. This slight difference is visible, while still allowing you to keep the chic look of a 1-carat ring.

Please note that a diamond's perceived size can change from one diamond shape to another. For example, a shallow-cut diamond such as the oval has an elongated and more visible surface compared to an asscher diamond, which holds a lot of ‘invisible’ carat weight due to its deeper cut pavilion. As such, a 1-carat oval diamond may appear roughly the same size as a 1.50-carat asscher diamond. 

When searching for a 1.50-carat engagement ring, please take care in selecting a shape you are happy with, and try to understand what is most important to you: whether that is diamond size, quality, or the overall look. Understanding where your expectations lie early on will help you select the ideal piece while still keeping within your budget.

This entirely depends on your diamond’s overall quality. Usually, diamond rings are easier to resell if they are in a classic shape and size, such as round or oval. However, the quality usually has to be very high, making the diamond rarer and thus more valuable. Ultimately, 1.50-carat diamond engagement rings can be worth the investment, however, this would be only under certain conditions.
