Product Description

The 4mm Polished Court Cobalt Ring is a traditional design made for those who prefer a slightly wider band without it feeling heavy. At 4mm in width and 2.0mm in depth, it has enough presence to stand out while still being slim enough for everyday wear.

This ring follows the court style, which is one of the oldest and most recognised shapes for wedding bands. The outside of the ring is softly rounded, while the inside has a gentle curve that makes it easy to wear for long periods of time. The comfort fit is often chosen by people who are not used to jewellery, as the rounded interior helps the ring feel smooth on the finger.

Finished to a high polish, the surface reflects the naturally bright colour of cobalt. The shade is close to white gold, which is one reason cobalt has become such a popular alternative. Many choose this design to sit neatly alongside an engagement ring, as the 4mm width pairs well with a variety of settings. It is also a good option for those who want a single band that feels noticeable without being too wide.

Cobalt has become well established in jewellery for its strength and modern appearance. It is much harder to bend than softer metals, giving the band a reassuring feel of solidity. Another advantage is that cobalt is hypoallergenic, so it can be worn safely by anyone with sensitive skin. These features make it a sensible choice for a wedding ring while also keeping the look clean and simple.

This ladies cobalt wedding ring is available in UK sizes J to S. The range covers many of the most requested women’s sizes. As cobalt is an extremely strong material, the rings cannot be resized, so it is important to order the correct size.

With its polished finish, rounded court profile and balanced 4mm width, the 4mm Polished Court Cobalt Ring offers a straightforward and elegant design in a modern metal that is both practical and attractive.

Scratch Resistance
We do not sell any ring as scratch proof, as all rings will eventually scratch with wear. How easy or hard this happens depends on their Mohs hardness. The higher the number, the harder it is to scratch, and the more resistant it is. You can compare this 4mm Polished Court Cobalt Ring with other rings on our Mohs hardness page. Scratches are a natural part of wear. The first mark often feels the worst, but over time the ring will develop its own patina.

Density
This 4mm Polished Court Cobalt Ring includes a density value to help you understand how heavy or light it will feel. Some people prefer a lighter ring, while others enjoy the weight of a solid metal. Density makes it easy to compare between materials. The higher the number, the heavier the ring. For example, titanium is one of the lightest at 4.5, while tantalum is around 16.6, making it nearly four times heavier.

Inside Engraving

Why not make this ring personal by adding an inside engraving? We can engrave up to 35 characters for an additional £35.00.

Need more than 35 characters? Because of ring size, font style, and certain characters, we set a safe limit. If you would like a longer message, please contact us. It may still be possible depending on the ring size and font.

You have other ideas? Contact us and we will do our best to accommodate your request.

Please note: once engraved, items cannot be returned for refund, exchange, or resizing. If you are unsure, you can order the item first and send it back later for engraving.

Engraving on this Ladies Cobalt Wedding Ring

This 4mm polished cobalt ring can be engraved on the inside to personalise it with a message, date or initials. At this width, clear fonts such as Arial, Calibri, Times New Roman and Verdana are recommended, as they remain sharp and easy to read once engraved.

Bold engraving is not available on this design. On a 4mm band, bold lettering can cause fine details to fill in, particularly with smaller characters like the dot on an i. To avoid this and keep the engraving legible, standard font weights are used.

Decorative or ornate fonts are also not suitable on a ring of this size. Their finer details do not reproduce clearly at 4mm, which can make the engraving difficult to read. Choosing one of the recommended fonts ensures the wording is neat, consistent and well-balanced within the polished interior.

    Great ring, great price!

    My husband and I both have quite active jobs where our platinum wedding rings would get badly scuffed. We opted for cobalt rings because they are so durable and still look great years down the line. This is my second cobalt ring owing to weight loss, it’s so comfortable and still looks new.

    Great little ring

    I love my new ring. It’s shiny, it’s hard wearing and most of all comfortable. It looks like a white gold or platinum ring in my opinion. I couldn’t decide what size I wanted and Titan Jewellery were really accommodating and sent out both sizes for me to try.

    Very Happy!!

    Bought for my husband as he is an electrician and wanted a ring that could withstand use at work. Free ring sizer was greatly appreciated when we did an exchange for size. Comparing the colour to my white gold ring this ring came up the same, arrived in a small box which is great for us. Very happy
