0.50-CARAT ENGAGEMENT RINGS

The Delicate Choice

Ever wondered what a diamond under 1-carat might look like on a ring? The popular expression may be to ‘go big or go home’, but that isn’t necessarily true. In fact, many actually prefer a more delicate style to wear day-to-day, with a clear focus on quality and craft.

0.50-carat engagement rings are the epitome of quality over quantity, especially if you are looking for a great stone that fits your price range. Weighing around 0.1g, these diamonds make for the most delicate rings, while still being fairly visible. In the end, less is always more.

— Miren Chovatiya, Diamond Specialist at 77 Diamonds

Frequently Asked Questions

The average price of a 0.50-carat diamond engagement ring largely depends on the quality of your centre stone and the overall ring design. For a classic 0.50 solitaire in white gold set with a good quality natural diamond, please expect between £1400 to £1800, excluding VAT.

If you choose a platinum ring with accent diamonds, such as a trilogy or a halo engagement ring, this may drive up the total cost of your design. However, it’s important to note the key element that will affect the price of your ring is, you guessed it: the diamond itself. 

Diamonds of a similar carat weight can vary in price depending on their quality, shape, and type. For example, an F coloured 0.50-carat round diamond can be around £100 less expensive than a D coloured diamond of the same size, cut and clarity. This is only two colour grades lower and still makes for a diamond of excellent quality.

Ultimately, it’s worth comparing different stone and ring combinations until you arrive at a final design that suits both your taste and chosen price range. At 77 Diamonds, our online diamond selection means you can fine tune your stone’s quality down to 0.01 of a carat, if you so wish. This allows you to pinpoint the one diamond that is perfect for you. 

The size of a diamond is a personal choice that reflects your style. Some actually like the delicate look of a small diamond placed on a solitaire ring. 0.50-carat diamond engagement rings are also a good choice for those looking to purchase a diamond at a fair price, and therefore tend to maximise on quality for this reason. 

If you like the look of a slightly larger diamond, you can also choose a halo engagement ring to give the illusion of a larger centre diamond. In the end, your diamond choice should be a compromise between your partner’s expectations, personal style and preferred price range.

Depending on the diamond shape, a 0.50-carat diamond may look roughly half the size of a 1-carat diamond. This is not a steadfast rule, however, as many diamond shapes are cut deeper and therefore hide a lot of carat weight. You can compare diamond sizes yourself with our helpful carat sizer.

A range of engagement ring styles will complement a 0.50-carat diamond. Our jewellery specialists recommend a classic solitaire for a delicate and minimalist touch, or a halo engagement ring if you are looking for your diamond to seem larger.

At 77 Diamonds, we offer one of the world’s largest and most detailed selection of diamonds, whether you prefer a natural, coloured or laboratory-grown stone. This obviously gives you a lot of choice when it comes to selecting your ideal stone, but we do also understand this may be a little overwhelming if you’re just getting started.

That is why our jewellery and diamond experts are always on hand to help, and guide you to the choice that suits your preferred price range, style and partner’s expectations. Contact us today for a chat, or book a tailored consultation in one of our showrooms. 

Yes, 0.50-carat diamonds can indeed look larger depending on their cut or shape. For example, elongated shapes such as the emerald, oval or marquise have larger surfaces that maximise carat weight and help make your diamond seem bigger. Our diamond specialists recommend you avoid deeper cut diamonds such as the asscher if you are looking to extend the visible carat weight of your stone.

Yes, of course. When making an engagement ring purchase online, it’s so important to know how it might look on a hand, especially if you are planning a surprise proposal. For this reason, a lot of our engagement rings are shown worn on a hand with either a 0.50-carat or 1-carat round diamond, giving you a good understanding of how it might look on your special day.

If you need to go further, you can also test diamond sizes and shapes on a hand, even selecting your favourite precious metal and preferred skin tone. Finally, you can come visit us in one of our showrooms to see a selection of rings and diamonds up close.
