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.









I needed a ring to wear every day to protect my wonderful wedding set and this is perfect
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.
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.
Gorgeous ring, so happy with it. Matches my white gold engagement ring perfectly but with a much nicer price tag!!
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
